General features:
These sensors enable the control with extremely high precision the rotation of a
toothed wheel or reference marks, switching off the load or giving an alarm in case
the speed falls below the minimum threshold. Thanks to the extremely wide measuring range they can be even used to control repetitive operations, signalling in case of unwanted stops. Further delays or other special functions may be implemented upon specific request.
The output is protected against wrong connection, overvoltages on line, and short cir-
cuit of the load. The connection is with a 4-wire M12x1 connector which must be ordered separately.
