button can be connected.
- BH 5910 multifunctional safety module.
Max. 2 x 10 NE 5021 and 1 E-stop button can be
connected.

Function

The magnetic switch consists of an transmitter and a receiver. The trans-
mitter is magnetic coded. The contacts of the receiver switch when it de-
tects the coding of the transmitter.
Manipulation with a standard magnet will not make the contact switching.
The contacts are protected against short circuit currents by series resi-
stors, so they cannot weld.
