6 Electrical connection

The electrical connection of the FMG90 is via the 4-pin plug M12x1 at the top.

The corresponding connection cables with moulded coupling socket are available in various lengths.

CAUTION! Electric current!

The electrical connection should only be carried out by a fully qualified electrician.

ªDe-energize the electrical system before connecting the FMG90.

Connection and wiring:

ªScrew the coupling socket of the connection cable to the plug of the FMG90.

ªTighten the knurled nut of the coupling socket with a maximum torque of 1 Nm.

ªConnect the connection cables according to the following wiring diagrams.

PNP frequency output:

Pull-up- / pull-down-resistors R.

We recommend using resistors of ~1 kΩ (12V) respectively ~2,2 kΩ (24V) and 0.25 W for

the pull-up / pull-down wiring.

Please note that the maximum signal current of 25 mA will not be exceeded.
