1. Attach the distance adjustment scale as shown in the figure and set it where the * mark is equal to the sensing distance. 

2. Turn the distance adjuster until the red spot is at point A (center of the distance adjustment scale). 

3. Remove the distance adjustment scale once the distance has been adjusted. Put a sensing object in place, and then adjust the sensitivity. 

## ● **Adjusting the E3S-LS20XE4 Convergent-reflective Sensor**

Use this method if the sensing object is more reflective than the background.

1. Set the sensitivity adjuster to the center as shown in the figure. 

2. Turn the distance adjuster counterclockwise until it is fully turned (L to S). 

3. Position the sensing object. 

4. Slowly turn the distance adjuster clockwise (S to L). 

5. Eventually the LIGHT (red) indicator will light. Turning the adjuster further will light the STABILITY (green) indicator. Leave the distance adjuster at this level. 

6. Adjust the sensitivity in this state.

Use this method if the background is more reflective than the sensing object.

## **Safety Precautions** 

## **WARNING** 

**This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes.** 

## **Precautions for Correct Use** 

Do not use the product in atmospheres or environments that exceed product ratings. 

If the sensing object has a metallic or shiny surface, the E3SR may not detect it properly. To avoid this situation, place the sensing object so that it is not at right angles to the Photoelectric Sensor.

- **Attaching the E39-S Slit** 

- The Slit can be fitted vertically or horizontally as indicated by the dotted line. Make sure that Slits for the Emitter and the Receiver are fitted in the same orientation. 

- Place the packing in the supporter and hook the claws on the indentations in the Sensor head. 

- If the supporter is contacting the mounting surface, insert a spacer to separate it. (Refer to _Slit Dimensions_ .) 

- An operating position accuracy of 0.1 mm max. can be achieved for a Through-beam Sensor without Slits.

Note 1. Only C42 models with die-cast cases are available. 

2. The Emitter for a Through-beam C4-type Sensor is the same as the Emitter for an E4-type Sensor. (E.g., E3S-5LE4) 

3. When a C- or B- type Sensor experiences a load short-circuit or overload, the output transistor will be turned OFF. Check the load conditions before turning the power back ON.

Note: Models numbers for Through-beam Sensors (E3S-@E4, E3S-@E41) are for sets that include both the Emitter and Receiver. 

The model number of the Emitter is expressed by adding "L" to the set model number (example: E3S-2LE4), the model number of the Receiver, by adding "D" (example: E3S-2DE4.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
