Product Description
The PA12BNT. is a through
beam sensor set special-
ly designed for elevators,
escalators, entrance control
to meet the requirements in
the door market. The hous-
ing is very robust and is
known for its high long-term
reliability. The emitter has
a mute input to turn it off
for evaluation of the sensor
function.
Available in 10-30 VDC
version.

Installation Hints
To 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
