E3S-CL1 5M

## Distance setting photoelectric sensor in metal housing **E3S-CL** 

- High water, oil and detergent resistance 

- Minimal black/white error for highest reliability detecting different colored objects (E3S-CL1) 

## Eliminates Background Influences with a 

## Hysteresis of Only 2% max. (E3S-CL1) 

The hysteresis is the industry's minimum 2% max. (E3S-CL1). As a triangulation measuring is used, objects behind the setting distance cannot be detected. The sensor is insensitive to the influence of background objects of high reflectivity, and stable detects works on a conveyor from above. The hysteresis of the E3S-CL2 is 10% max. of the detecting distance (5% max. for white paper).

## Output selection switch 

- A When using the sensor with NPN output, move the switch to the NPN position. 

- B When using the sensor with PNP output, move the switch to the PNP position. 

- Mode selection switch 

- A When using the sensor with Light-ON, move the switch to the position. 

- B When using the sensor with Dark-ON, move the switch to the position. 

- Distance Adjuster 

- A Turning the distance setting adjuster clockwise (to the Max position) increases the detecting distance, and turning it counterclockwise (to the Min position) decreases the distance. 

- B The distance setting adjuster is a 6-turn endless adjuster ranging from the Min position to the Max position, and its number of turns is displayed on the setting distance indicator according to the rotation of the adjuster.

## Precautions 

## Correct Use 

Design Cable 

The oil-resistant cable is used  to ensure oil resistance. (E3S-CL2) 

## Installation 

Sensor installation 

Mounting orientation 

• Install the photoelectric sensor in such manner that its detection surface and the object surface are parallel (without inclination Sensing surface relative to the sensing object). Sensing object surface If the sensing object has a glossy surface, incline the Sensor by 5° to 10° as shown on the right. In this case, ensure that the Sensor is not influenced by Glossy object any background objects. 

- If there is a mirror-smooth object under the photoelectric sensor, operation may become instable. Therefore, incline the photoelectric sensor as shown below or move it away from the object.

- Install the photoelectric sensor in either of the following orientations, being careful of the direction in which the sensing object will move.

- Also, when the color/material of the sensing object varies extremely, install the photoelectric sensor in either of the following orientations.

Movement direction<br>Movement direction<br>**----- End of picture text -----**<br>


- Install the photoelectric sensor so that the sun, fluorescent lamp, incandescent lamp or any other strong light will not enter the directional angle range of the sensor. 

## Mounting Precautions 

- Do not strike the Photoelectric Sensor with a hammer or any other tool during the installation of the Sensor, or the Sensor will loose its water-resistive properties. 

- Use M4 screws. 

- Tighten the screws to the torque of 1.2 Nm max.

Oil resistance/chemical resistance (E3S-CL2) 

For the oil resistance ofE3S-CL2, the Sensor has passed tests on the oils given in the following table. Refer to the table for examining the oil to be used. Depending on the oil type, however, the Sensor may not be able to exhibit its performance.

|Note: 1 .E3S-C was submerged in the oils in the above table at 50°C for 240|||||



hours, and passed the test of 100-M or more insulation resistance. 2 .For use in the environment where E3S-C is exposed to the oil other than those in the above table, use the dynamic viscosity and PH in the above table. Pre-check the oils since the sensor may be affected by additives etc. in the oils.
