Photoelectric Sensor

E3S–R

High Performance, Retroreflective

Photoelectric Sensor Incorporates

Polarised Lenses to give Reliable

Detection of Transparent or Shiny

Objects

Both NPN and PNP outputs are wire configurable for

Light-ON or Dark-ON operation.

Small die-cast metal housing (IP67) offers reliable

performance in aggressive environments.

Mutual
