Product Description
2.1
Function
General
The device is an inductive dual sensor. Dual sensors are used, for example, to detect the final
positions of valve positions in valve actuators.
Inductive dual sensors consist of 2 sensor circuits arranged one above the other.
Each sensor has its own coil. If a measuring plate is inside the sensing range of one
of the coils, the magnetic field of the coil is influenced and an electrical switching signal
is generated.
The device is a NAMUR sensor with 2 independent sensor circuits in 2-wire configuration.
The device transmits the binary signal according to NAMUR to a connected control unit.
A control unit can, e. g., be a switch amplifier or an I/O card in a PLC.
NCN3-F31K2(M)-N4-B*3-S
The sensor has two separate sensor circuits with NC function (normally-closed).
The device is in high impedance state when a measuring plate is located within the sensing
range of the respective sensor circuit.
The sensor has a rated operating distance s
n
of 3 mm.
NCN3-F31K2-N5-B*3-S
The sensor has two sensor circuits. One sensor circuit of these sensor circuits is activated
depending on the polarity of the supply voltage. The active sensor circuit is in high impedance
state when a measuring plate is located within the sensing range of this sensor circuit.
The sensor has a rated operating distance s
n
of 3 mm.
