* The operation mode depends on the wiring of the
brown and blue lines.
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.
