Fine Tuning Fiber Photoelectric Sensor
High-precision Sensing with Auto- and Manual-tuning
Solves All the Problems of Conventional Models Suitable for high-precision positioning using the fine sensitivity adjustment function. Manual-tuning allows threshold adjustments while sensing objects are moving. Operation conditions can be seen at a glance through the incident level indicators and threshold indicators. Auto-tuning feature incorporates an automatic sensitivity compensation function ensuring an optimum margin for changes in sensing objects or ambient environments. Offers the longest sensing distance. Newly added mark-sensing models (blue LED).

Sensing Slight Differences
Application Examples Detection of slight differences in reflection. Detection of translucent objects. Detection of object surface irregularities. Color discrimination. Detecting IC Chips on Film Sheet
Sensitivity Setting Without Objects
Application Examples Detection of minute passing objects. Detection of lead wires. High-precision positioning.

E3X-NH Sensitivity Setting (Teaching)
Note:
E3X-NH
The sensitivity of the E3X-NH/NHB is factory-set to maximum. When resetting the sensitivity of the E3X-NH to maximum after with/ without-object teaching or positioning/no-object teaching, follow the steps described below.
1. Maximum Sensitivity Setting
1. Set the mode selector to TEACH. Press the SET button for three seconds minimum. Be sure that all the threshold indicators (red) are ON. The built-in buzzer beeps once when the threshold indicators are ON.
2. With/Without-object Teaching
1. Set the mode selector to TEACH. Locate the sensing object in the sensing area and press the SET button once. Be sure that all the threshold indicators (red) are ON. The built-in buzzer beeps once when the threshold indicators are ON.
Press for 3 s min.
Press once for 0.5 to 2.5 s
2. The sensitivity will be set when the built-in buzzer beeps continuously and all the incident level indicators (green) are ON.

E3X-NH Sensitivity Adjustment (Tuning)
A. Manual-tuning (Fine Sensitivity Adjustment)
Note: The auto-tuning function will be disabled if manual-tuning is executed. 1. After setting the sensitivity of the E3X-NH, select the adjustment direction with the UP/DOWN selector in the ADJ mode.

B. Auto-tuning (Automatic Sensitivity Compensation)
1. Set the mode selector to TEACH. Press the SET button once without a sensing object in the sensing area. Be sure that all the threshold indicators (red) are ON. The built-in buzzer beeps once when the threshold indicators are ON.
(2) (1) Press for 0.5 to 2.5 s
2. Press the SET button in ADJ mode. Be sure that the threshold changes whenever the SET button is pressed. If two threshold indicators are ON, the threshold will be set to the middle value between the values corresponding to these indicators.
2. Set the mode selector to ADJ and press the SET button for three seconds minimum. Be sure that the threshold indicator (red) flashes. The built-in buzzer beeps continuously.
(2) Press for 3 s min. Press for 0.5 to 2.5 s (1)
3. Set the mode selector to RUN.
3. Set the mode selector to RUN. The threshold indicator (red) will continue to flash while the the auto-tuning function is enabled.

Remove the protective cover, insert the fiber into the Amplifier, and lower the lock button until a click is heard. After cutting the fiber using the E39-F4 Fiber Cutter, put an insertion mark on the fiber as a guide for correct insertion into the Amplifier, and then insert the fiber up to this mark. 2. Disconnection Remove the protective cover and raise the lock lever to pull off the fiber. (Before removing the fiber, be sure to confirm that the lock is released so as to maintain the fiber properties.)

Cutting Fiber
Insert a fiber into the Fiber Cutter and determine the length of the fiber to be cut. Press down the Fiber Cutter in a single stroke to cut the fiber. An insertion mark can be placed on the fiber to serve as a reference when inserting the fiber into the Amplifier. Use the following procedure. Confirm through the Cutter hole that the fiber is inserted beyond the insertion mark hole so that the insertion mark is properly indicated, and then press firmly down on the Cutter.
(2) 20 mm min.
Note:
Insert the fiber in the direction indicated by the arrow.
Connection
Do not pull or press the Fiber Units. The Fiber Units have a withstand force of 9.8 N (1 kgf) or 29.4 N (3 kgf) (pay utmost attention because the fibers are thin). Do not bend the Fiber Units beyond the permissible bending radius. Do not bend the edge of the Fiber Units (excluding the E32-TjR and E32-DjR).

Insert the fiber into the Amplifier up to the insertion mark. Proper fiber performance will not be achieved unless the fiber is inserted all the way to the insertion mark. (This method is applicable to standard, 2.2-mm-diameter fibers only.)

Mounting
Mounting 1. Mount the front part on the mounting bracket (attachment) or a DIN track. 2. Press the back part onto the mounting bracket or the DIN track. Note: Do not mount the back part onto the mounting bracket or the DIN track first and then mount the front part on the mounting bracket or the DIN track, or the mounting strength of the Amplifier Unit may decrease. Dismounting By pressing the Amplifier Unit in direction (3) and lifting the fiber insertion part in direction "4" as shown in the following, the Amplifier can be dismounted with ease.

E3X-NH
Turning the Power ON After the E3X-NH/NHB is turned ON, the E3X-NH/NHB will be ready to operate in 100 ms maximum. If power is supplied to the E3X-NH and the load is connected to the E3X-NH/NHB independently, be sure to turn ON the power supply connected to the E3X-NH/NHB first. When the power is turned ON, the operation indicator will be ON momentarily. Note that this will not have an effect on performance since no control output will be generated. Mutual Interference Protection Function Perform two-point teaching if two to three Fiber Units are closely mounted together, at which time supply power only to the Unit in teaching operation in turn or block the emitters of the Fiber Units not in teaching operation. EEPROM Writing Error Write errors may result at the time of teaching due to power failure or static noise, in which case the Unit beeps and the operation indicators flash. If any of these occur, re-input teaching using the teaching button on the Amplifier. Minute Sensing Object This datasheet shows typical examples for detecting minute objects. These typical examples are for reference use only, because these example operations were tested on Units sampled at random from a lot and the values described are average values. Do not assume that all Units ensure such operations.
E3X-NH
Others When the power is OFF: The moment power is turned OFF, the E3X-NH/NHB may output a pulse signal which could affect the operation of the devices connected to it. This will occur more often if power is supplied to the E3X-NH from an external power supply, thus affecting the connected timer and counter. Use a built-in power supply as much as possible to avoid this. In a case where the cord is extended, use a wire with 0.3 mm2 min. The total length of the cord should be 100 m max. Power supply: If a standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal must be grounded, or otherwise the E3X-NH can malfunction influenced by the switching noise of the power supply. The supplied voltage must be within the rated voltage range. Unregulated full- or half-wave rectifiers must not be used as power supplies. Do not lay wiring to the Optical Sensor together with power lines in the same piping or ducts. Doing so will cause induction between the lines, possibly resulting in faulty operation or destruction. Always lay wiring to the Optical Sensor in separate or dedicated piping.

Applications
E39-F10 Fiber Connector Use the following procedure (refer to the figure) to connect fibers via the Fiber Connector.
Splice Retention unit Retention unit Protective spiral tube Fiber Unit
Protective Spiral Tube Insert a fiber to the Protective Spiral Tube from the head connector side (screwed) of the tube.
Push the fiber into the Protective Spiral Tube. The tube should be straight so that the fiber is not twisted when inserted. Then turn the end cap of the spiral tube.
Fiber Unit
Each Fiber Unit should be as close as possible before they are connected. Sensing distance will be reduced by approximately 25% when fibers are connected. Only fibers with a 2.2-mm dia. can be connected. (Refer to page 9 for applicable Fiber Units.)
