ee-sx91 6 safety precautions refer to warranty and limitations of liability . this product is not designed or rated for ensuring safety of persons either dir ectly or indirectly. do not use it for such purposes. power supply voltage do not exceed the voltage range indicated in the specifications. applying a voltage exceeding the specifications or using an ac power supply may result in rupture or burning. faulty wiring do not reverse the power supply polarity. doing so may result in rupture or burning. do not short-circuit the load. (do not connect to the power supply.) doing so may result in rupture or burning. dispose of this product as industrial waste. installation it is assumed that ee-sx91 sensor s will be built into a device. these sensors use non-modulated li ght and are not equipped to deal with interference from an exte rnal light source. when they are used in locations subject to external light interference, such as near a window or under an incandescent li ght, install them to minimize the effects of external light interference. mount the sensors securely on a flat surface. use m3 or m2.0 screws to secure the photomicrosensor. (the stronger m3 screws are recomm ended. in addition, use flat washers and spring washers to prev ent the screws from loosening.) refer to the following table fo r the correct tightening torque. if the sensor is to be used on a moving part, secure the cable connection point so that it is not directly subjected to stress. wiring unused output lines be sure to isolate output lines that are not going to be used. connecting to devi ces with voltage i nput specifications a sensor with an open-collector out put can be connected to a counter with a voltage input by connecti ng a resistor between the power source and output. select a resistor with reference to the following example. the resistance of the resistor is generally 4.7 k ? and its wattage is 1/2 w for a supply voltage of 24 v and 1/4 w for 12 v. example: ee-sx91 series load resistance of 4.7 k ? connected in a counter counter specifications the high and low levels are found using the following formulas. the input device specifications must satisfy both formulas. high level: low level: input voltage v l 1.0 v (residual voltage for 100-ma load current) note: refer to the ratings of the sensor for the residual voltage of the load current. warning precautions for safe use sensor brown blue load load black white sensor brown blue black white ? + load load + + ? black white load d short-circuit) (loa load ck ( precautions for correct use screw diameter tightening torque m2.0 0.15 nm max. m3 0.54 nm max. input impedance 5.6 k ? voltage judged as high level (input on) 4.5 to 30 vdc voltage judged as low level (input off) 0 to 2 vdc sw main circuit tr +vcc ee-sx91 series counter (voltage input type) insert a resistor output 0 v 0 v r 24 v power supply z input terminal (cp) (input impedance: approx. 5.6 k ? ) input voltage v h = r+z z vcc = 4.7 k+5.6 k 5.6 k 24 v = 13 v load current ic = r vcc = = 5.1 ma 100 ma r 24 v
ee-sx91 7 other precautions do not disconnect the connector fr om the sensor when power is supplied to the sensor, or sensor damage could result. do not install the sensor in the following places to prevent malfunction or trouble: 1. places exposed to dust or oil mist 2. places exposed to corrosive gas 3. places directly or indirectly ex posed to water, oil, or chemicals 4. outdoor or places exposed to intensive light, such as direct sunlight be sure to use the sensor under the rated ambient temperature. the sensor may be dissolved by exposure to organic solvents, acids, alkali, or aromatic hy drocarbons, aliphatic chloride hydrocarbons causing det erioration in charac teristics. do not expose the sensor to such chemicals. make sure the total length of the power cable connected to the product is less than 10 m.
