E4PA-N ultrasonic displacement sensor 1 ultrasonic displacement sensor E4PA-N now, more advanced with a new mutual interference prevention function. application examples features high-precision detection with a wide range of measurements. four types of sensors are available with max- imum sensing distances of 0.5 m, 2 m, 4 m, and 6 m. with the 0.5-m type, a repeat accu- racy of 1 mm or better has been achieved. a setting plug with a temperature compensation function makes it easy to set the sensing range. the sensing range can be set by the setting plug, which is included with the sensor. no special con- troller is required. the setting plug?s built-in tem- perature sensor provides superior temperature characteristics of 1% fs. the sensor is ultrasonic, so it is not affected by the color of objects. a variety of materials can be measured, including transparent and reflective objects. measurements ar e performed with no contact, so even highly-viscous li quids are no problem. the mutual interference prevention function allows up to five sensors to be used in close proximity. detecting slackness in sheet materials detecting liquid levels remotely detecting lcd wafers detecting dies setting plug ok transparent objects ok black objects reflective ob j ects ok ok highly viscous liquids

4 E4PA-N ultrasonic displacement sensor nomenclature setting plug the E4PA-N is set up by aligning the notch on the sensor with one of the triangular marks on the setting plug and inserting the setting plug into the sensor. note: 1. analog output characteristics when setting plug is inserted at e2/ e3 position: the analog output characteristics will change from (1) to (2) to (3), in that order, each time the setting plug is inserted with the e2/e3 position aligned with the notch on the sensor. 2. the analog output value can be compensated so that the sensing surface (0 mm) of the sensor is 4 ma/0 v regardless of the nearest sensing point setting. this function is useful when using controllers without a scaling function. sensing is not possibl e, however, for characteristics within the dead band distance and current/voltage output values may not be stable. indicator display and anal og output characteristics note: 1. lit: the sensing object is within the sensing range. not lit: the sensing object is not within the sensing range. 2. output indicator just prior to occurrence of malfunction. mutual interference prevention the E4PA-N provides a sync input to prevent mutual interference. when the fifth pin of the sensor i/o connec tor?s m12 connector is interconnected, mutual interference can be prevented for up t o five units. the sensors will mutually oscillate, however, ca using a delay in measurement time by the mutual interference cycle time per sensor number of units + response time. when the sync inputs are not connected, the mutual interference prev ention function is disabled. (for example, if three e4pa-ls200-m1-n are connec ted, the response time for one sensor is 34 ms 3 sensors + 195 ms = 297 ms. sensor setting plug triangular mark on setting plug notch on sensor setting plug connector m12 connector for sensor i/o (5 poles) notch on sensor run indicator (yellow) power indicator (g reen ) run indicator (yellow) error indicator (red) position function a1 nearest sensing point a1 a2 farthest sensing point a2 e2/e3 (see note 1.) analog output characteristics 1. increase: as the distance increases, the output in- creases.

E4PA-N ultrasonic displacement sensor 5 operation setup and operating procedure the E4PA-N is factory-set for the decrease mode for analog out put characteristics and for the maximum sensing range. these sett ings enable scaling with the connected device (e.g., the k3 nx). in this case, only step 4 is required. to change the analog output range, follow steps 1 to 4 below. 1. preparation for setup note: do not insert the setting plug yet. it must be inserted within five minutes after the power is turned on, however, or the set- up will not be possible. if that happens, power up again and start over. 2. setting sensing range 3. setting analog output characteristics mode 4. setting temperature compensation mode note: if the reflection from the sensor is extremely weak, or if t he sensing object is set outside of the sensing range, the error in dicator (red) will flash to show that the sensing range is not accurately set. if the setting plug is left removed for five minutes or longer, tem perature com- pensation will be disabled (status before setting). if it becomes necessary to change the settings for step 2 (sensing range) or step 3 (analog output characteristics mode) after steps 1 through 4 have been completed, the contents of all the previous settings will be remembered, so only the items to be changed need to be reset. go through the steps in order, from 1 to 4, and reset only the items to be changed. step setting/operation 1 remove the setting plug. 2 turn on the power. (see note.) 3 proceed to step 2 setting sensing range. step setting/operation 1 place the sensing object at the nearest point within the sensing range. 2 insert the setting plug at the a1 position. (align the notch on the sensor with the a1 triangular mark on the setting plug.) the power indicator (green) and the a1 run indicator (yellow) with flash, showing that the near dis- tance has been correctly set. 3 remove the setting plug. (in this state, the setting is confirmed and recorded.) 4 place the sensing object at the farthest point within the sensing range. 5 insert the setting plug at the a2 position. (align the notch on the sensor with the a2 triangular mark on the setting plug.) the power indicator (green) and the a2 run indicator (yellow) will flash, showing that the far distance has been correctly set. 6 remove the setting plug. (in this state, the setting is confirmed and recorded.) 7 proceed to step 3 setting analog output characteristics mode. 50 mm (for e4pa-ls50-m1-n) sensing object a1 a2 e3 e2 a1 position 500 mm (for e4pa-ls50-m1-n) sensing object a2 position a1 a2 e3 e2 step setting/operation 1 insert the setting plug at the e2/e3 position.

(align the notch on the sensor with the t triangular mark on the set- ting plug.) 2 leave the setting plug inserted where it is. (this completes the set- up.) note: to maintain the temperature compensation, leave the setting plug inserted during operation. if it is re- moved from the e4pa, the temperature compensa- tion will be disabled. e2/e3 position a1 a2 e3 e2 a1 a2 e3 e2 a1 a2 e3 e2 a2 run indicator (yellow) flashing: analog output characteristics: decrease mode in this mode, the analog output decreases (20 to 4 ma/10 to 0 v) as the sensing object nears the e4pa within the sensing range. a1 run indicator (yellow) flashing: analog output characteristics: increase mode a1 and a2 run indicators (yellow) flashing at the same time: analog output characteristics: output from 0 mm in this mode, the analog output increases (4 to 20 ma/0 to 10 v) as the sensing object nears the e4pa within the sensing range. in this mode, the analog output decreases (20 to 4 ma/10 to 0 v) as the sensing object nears the e4pa between the farthest sensing point and 0 mm . the mode changes when the setting plug is reinserted at the e2/e3 position. the mode changes when the setting plug is reinserted at the e2/e3 position. t position
6 E4PA-N ultrasonic displacement sensor safety precautions precautions for safe use design power supply if possible, use a power supply without overcurrent detection. this sensor uses a dc-dc converter in the power supply circuit. if the power supply has overcurrent detecti on, the protective circuit may be activated by the inrush current. recommended power supply: omron s82-series power supply (capacity: 15 w min.) wiring power supply voltage do not exceed the operating voltage range. using a higher voltage or using an ac power supply (100 vac or more) for a dc sensor can cause explosion or burning. faulty wiring be careful not to make wiring mistakes such as reversing the power supply polarity. faulty wiring can cause explosion or burning. operating environment do not use the sensor in an environment where inflammable or explosive gas is present. others do not attempt to disassemble, repair, or modify any units. any at- tempt to do so may result in malf unction, fire, or electric shock. dispose of sensors as industrial waste. precautions for correct use design sensor ambient temperature and humidity the acoustic velocity generally fl uctuates approximately 0.17% with each 1 c of temperature change. for example, if the ambient tem- perature increases from 20 to 40 c, then the acoustic velocity will increase by 3.5%. moreover, the acoustic velocity will increase by 2% in dry air compared with air with 100% humidity. test the environ- mental conditions where the sensor will actually be used. mutual interference separate the sensors as specified in the following table when using two or more sensors in close proximity to one another. the mutual interference prevention function c an be used with up to five sensors. parallel arrangement note: the values shown in the following table are examples for ref- erence only. the actual values will vary depending on the sur- face conditions of the sens ing object, and on the ultrasonic waves that are reflected. moreov er, if the sensing object is in- clined, the y value in the t able will be increased further. facing arrangement sensing object the sensing object may be solid, liquid, or powder, and the detec- tion capability of the sensor wi ll vary depending on the surface con- ditions of the object. if the surface irregularities are no more than 0.2 mm, then the specified sensing dist ance will apply. materials such as fine powder, felt, cotton, and ot her materials that absorb sound should be tested before using the sensor. if the surface temperature of the sensing object is over 100 c, there will be very little ultrasonic reflec tion. conduct tests before using the sensor. influence of sensing angle ultrasonic displacement sensors can detect solid, liquid, or powder sensing objects, but the surface of the sensing object will affect the measurement. dented surfaces or sensing objects with an angled surface require a tilt angle within 3 max. to achieve accurate sens- ing. installation mounting the sensor the sensor must be mounted using the nuts provided, and tightened to a torque of 15 nm max. if the sensor malfunctions due to noise, insert insulation between the sensor and the mounting base (metal). atmosphere to ensure reliability and long servic e life, do not use the sensor out- doors or in places that exceed the rated temperature. ultrasonic sensors use air as t he transmission medium, so if there are local temperature differences there may be malfunctioning due to reflection and refraction at the boundaries, and the detection dis- tances change where wind blows. therefore, the sensor should not be used near equipment such as forced-air ventilators. jets from air nozzles include various frequencies, so they can affect the sensor and should not be used nearby. water drops on the sensor surf ace shorten the sensing distance. wiring considerations cable length the cable must be no longer than 10 m. high-voltage lines do not lay power supply cable for the E4PA-N ultrasonic displace- ment sensor together with high-vol tage lines or power lines. placing them in the same conduit or duct may result in interference, damage, or malfunction. model y e4pa-ls50-m1-n 0.3 m min. e4pa-ls200-m1-n 1 m min. e4pa-ls400-m1-n 2 m min. e4pa-ls600-m1-n 2.5 m min. y E4PA-N E4PA-N sensing object sensing object model y e4pa-ls50-m1-n 2 m min. e4pa-ls200-m1-n 8 m min. e4pa-ls400-m1-n 16 m min. e4pa-ls600-m1-n 25 m min. x E4PA-N E4PA-N 3 3 E4PA-N sensing object
