Low-Cost Molded

Industrial VRS Magnetic

Speed Sensors

DESCRIPTION

Low-Cost Molded VRS Sensors are designed for use in OEM

(Original Equipment Manufacturer) applications.

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).

Passive VRS (Variable Reluctance Speed) Magnetic Speed

sensors are simple, rugged devices that do not require an

external voltage source for operation.

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.

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.

Honeywell also offers VRS sensors for general purpose, high

output, power output, high resolution and high temperature, as

well as hazardous location applications.
