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