High Output VRS sensors are designed for use in applications where

higher output voltages are needed. They perform best at low to medium

speeds with medium to high impedance loads. Front -End Sealed

versions are available for use where the sensor is exposed to fluids,

lubricants or adverse environmental conditions. 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,

power output, high resolution, high temperature, and hazardous

location applications, as well as low-cost molded versions.
