3045A

Actual product appearance may vary.

High Resolution VRS sensors are designed for use in applications

where precise timing pulse is required, and/or fine pitch gears are

used. Proper alignment of the sensor is required. 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 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
