VF401
2-Wire Solid State Switch
DESCRIPTION
The VF401 allows a greater air gap between the target and the
sensor with reduced loss in sensor signal or accuracy.
The VF401 is a 2-wire MR (magnetoresistive) bridge array in a
miniature plastic package, designed for sensing fine pitch ring
magnets.
Patent number 6,297,628.
FEATURES
POTENTIAL APPLICATIONS
•
•
•
•
Wide operating temperature range
2-wire operation means less wiring
Enhanced sensitivity, ±7 gauss typical
Output pattern independent of gap between target and
sensor
•
•
•
•
Speed encoding using a multipole ring magnet
Enhanced accuracy cam and crank position sensing
Wheel speed sensing
Window lift applications

Notes:
1. Absolute maximum ratings are the extreme limits the device will momentarily withstand without damage to the device. Electrical
and magnetic characteristics are not guaranteed if the rated voltage and/or currents are exceeded nor will the device necessarily
operate at absolute maximum ratings.
2. Customer supplied sense resistor required for negative reverse voltage.

Notes:
1. Vcc is limited by Vh and the value chosen for the sense
resistor.
2. Sensor operation at limits for air gap is dependent on ring
magnet.
