Distance adjustment scale Distance adjuster Sensing object Distance adjuster * Align the distance adjustment scale with the groove on the Sensor. 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. Center Background object 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. Adjustment Method 2 Use this method if the background is more reflective than the sensing object. Distance adjuster Sensing object Center Background object 1. Set the sensitivity adjuster to the center as shown in the figure. 2. Turn the distance adjuster clockwise until it is fully turned (S to L). 3. Remove the sensing object. 4. Slowly turn the distance adjuster counterclockwise (L to S). 5. Eventually the LIGHT (red) indicator will light. Turning the adjuster further will light the STABILITY (green) indicator. 6. Adjust the sensitivity in this state. 7 E3S Safety Precautions ● Sensors with Open-collector Outputs Sensors with Open-collector Outputs WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes. Type 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.

Load (relay) ● 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.

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.
