Ordering Key
The PA18CSP.. is a family of
inexpensive general purpose
Polarized Retro-reflective
sensors in industrial stan-
dard 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 4-wire com-
plementary (NO and NC)
output in NPN (current sink-
ing) or PNP (current sour-
ing).
