Product Description

The PA18CLP.. is a family of
inexpensive general purpose
Polarized Retro-reflective
sensors in industrial stan­dard 18 mm cylindrical
PBTP housing. They are
useful for simple applica-

tions where a basic sensor
provides adequate sensing
performance. The sensors
are simple to use and no
adjustment are necessary.
The output is a 2-wire NO or
NC thyristor (SCR) output.
