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.

Sensors with Different Orientations
The E3S-5, E3S-DS30, and E3S-R2 that sense in different
directions can be made.
