Pin
Description
Pin 1
GND
Brown (BN)
Low-resistance GND connection of the cylinder.
Depending on the current, the GND potential is approx. 0.2 to 0.6V higher than the negative potential at the
M12power connector. Only use this pin if you want to connect an interface that is galvanically isolated from
M12power.
Do not connect to the supply voltage!
Not connected – Signal GND
Pin 2
Blue (BU)
Leave unconnected
Pin 3
Potential free switch at a middle position
White (WH)
The linear drive contains a central signal switch S3, which is designed as a normally closed (NC) contact. The
two contacts of the switch are led out to the M12 con-
Pin 4
nector and have no electrical connection to other po-
Green (GN)
tentials within the linear drive.
The position PS3 of the pushbutton is defined on the
specification drawing of the linear
drive.
The switch is triggered when the
linear drive is at a standstill or in
motion. It is independent of the
electrical supply to the linear
drive.
