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.
