KJT-3024-LY Speed Sensors M12, 55Vp-p, .25mm 3/8-24 UNF-2A, 9.5mm
High Resolution VRS sensors are designed for use in
applications where precise timing pulse is required, and/or fine
pitch gears are used. Proper alignment of the sensor is
required.
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.
