Power Output
Industrial VRS Magnetic
Speed Sensors
DESCRIPTION
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.
FEATURES

•
Customized VRS products for unique speed sensing
applications
•
Housing diameter: 5/8 in (M16)
•
Housing material/style: stainless steel threaded
•
Terminations: MS3106 connector, preleaded
•
Output voltage: 70 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 general purpose, high
output, high resolution, high temperature and hazardous
location applications, as well as low-cost molded versions.
