General Purpose
Industrial VRS Magnetic
Speed Sensors
DESCRIPTION
General Purpose VRS sensors are designed for use in
applications with medium to high speeds or in electrically noisy
environments with relatively small air gaps.
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.
FEATURES
Self-powered operation
Direct conversion of actuator speed to output frequency
Simple installation
No moving parts
Designed for use over a wide range of speeds
Adaptable to a wide variety of configurations
Customized VRS products for unique speed sensing
applications
Housing diameters: 5/8 in (M16), 3/8 in (M12) mm,
1/4 in (M8), 10/32 in
Housing materials/styles: stainless steel threaded or
smooth
Terminations: MS3106 connector, preleaded
Output voltages: 8 Vp-p to 40 Vp-p
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 high output, power
output, high resolution, high temperature and hazardous
location applications, as well as low-cost molded versions.
