Inductive sensor

NCN3-F31-B3B-V1-K

Function

The NCN3-F31-B3B-V1-K is an inductive dual sensor used to indicate the valve positioning of actuators. The dual sensor is
mounted directly on the actuator using two screws. Additional adjustment is not necessary.

A cable connection on the sensor is used directly for the valve controls. The NCN3-F31-B3B-V1-K is connected via a M12x1
screw fixing to the bus line. This makes it possible to transmit both the switch signal for the valve and the messages of the sensors
via AS-Interface. They are both powered directly through the bus cable. Moreover, the valve is monitored for lead breakage and
short circuit. The D1 data bit monitors the fault signal.

The sensors can be programmed as normally closed and normally open contacts (parameter bit P1 and P2). If there are no
communications on the bus cable, the valve is automatically de-energised. This communication monitoring can be turned off via
the parameter bit P0.

The current switching states are displayed by means of yellow LEDs.
