Photoelectrics
Diffuse-reflective
Type PA18CLD0.T, AC, PBTP-housing
The PA18CLD.. is a family of
inexpensive general purpose
Diffuse-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 ne cessary (except 400 mm diffuse adjustable type). The
output is a 2-wire NO or NC
thyristor (SCR) output.

Installation Hints
Relief of cable strain
Protection of the sensing face Switch mounted on mobile carrierTo avoid interference from inductive voltage/
current peaks, separate the prox. switch power cables from any other power cables, e.g.
motor, contactor or solenoid cables
Incorrect
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided
