Installation
Mounting
1)
When installing the sensors, make sure that the maxi
mum range is not exceeded and if two separate sys
tems are mounted close to each other place the sen
sors so crosstalk is avoided.
2)
3)
To protect the receiver and the transmitter from dam
age, proper fittings must be used in the installation.
Connect the receiver and the emitter to the dedicated
terminals on the S142... system.
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
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
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
