Product Description
The PA18CSP.. is a family of
inexpensive general purpose
Polarized Retro-reflective
sensors in industrial standard 18 mm cylindrical
PBTP housing. They are
useful for simple applications where a basic sensor
provides adequate sensing
performance. The sensors
are simple to use and no
adjustment are necessary.
The output is a 4-wire complementary (NO and NC)
output in NPN (current sinking) or PNP (current souring).
