Power Output VRS Sensor, 15,9 mm [0.625 in] M16 diameter, 70 Vp-p, -55 ºC to 120 ºC [-67 ºF to 250 ºF], 12 DP (module 2.11) or coarser, 40 kHz, 130 mm [5.10 in] approx. length

Power Output VRS sensors are designed for driving low resistance loads at large air gaps in applications where larger actuators may be used.

Passive VRS (Variable Reluctance Speed) Magnetic Speed sensors are simple, rugged devices that do not require an external voltage source for operation.

A permanent magnet in the sensor establishes a fixed magnetic field. The approach and passing of a ferrous metal target near the sensor’s pole piece (sensing area) changes the flux lines of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding, which is attached to the output terminals.

The output signal of a VRS sensor is an ac voltage that varies in amplitude and wave frequency as the speed of the monitored device changes, and is usually expressed in peak to peak voltage (Vp-p).

One complete waveform (cycle) occurs as each target passes the sensor’s pole piece. If a standard gear were used as a target, this output signal would resemble a sine wave if viewed on an oscilloscope.

Honeywell also offers VRS sensors for general purpose, high output, high resolution, high temperature and hazardous location applications.
