Code
The magnetic switch NE 5020 includes a magnetic coded transmitter and
a receiver as decoder. The semiconductor outputs close, when the recei-
ver recognises the right code from the transmitter. The control unit detects
cross faults on the lines 14 and 24. The control unit is switched off when
a fault is detected and inhibits a new start. The switch is protected against
short circuits and peak voltages.
The NE 5020 is connected to the control unit BG 5925/920 or LG 5925/920
according to the application example below.
The magnetic switch NE 5020 is suitable to detect the closed state of sa-
fety gates, sliding gates and removable covers also under rough ambient
conditions or for hygienic requirements. The corresponding control unit is
BG 5925/920 or LG 5925/920.

The code of transmitter and receiver are identically on delivery. This can
be verified by a mark on the test sticker.
