Safety Precautions

This product is not designed or rated for

ensuring safety of persons.

Do not use it for such purposes.

Do not use the product in atmospheres or environments that

exceed product ratings.

If the sensing object has a metallic or shiny surface, the E3S-

R 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.

Sensor with Slits

● Sensors with Open-collector Outputs

Sensors with Open-collector Outputs

The model numbers are as follows:

Example:

E3S-DS10E4 (E type)

E3S-DS1C4 (C type)

E3S-DS1B4 (B type)

C4 (C41, C42) Sensors

C4 (B41, B42) Sensors

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.
