VF401 - 2-Wire MR Fine Pitch Ring Magnet Sensor

General Description

The VF401 is a high performance, digital, 2-wire, MR (magnetoresistive) sensor in a miniature, flat, TO-92-style, plastic package with a current output, designed for sensing fine pitch ring magnets.

Key Features

  • Robust design operating from -40 °C to 150 °C [-40 °F to 302 °F] can withstand short durations up to 175 °C [347 °F], allowing use in potential.

DESCRIPTION The VF401 is a high performance, digital, 2-wire, MR (magnetoresistive) sensor in a miniature, flat, TO-92-style, plastic package with a current output, designed for sensing fine pitch ring magnets. The unique VF401 bridge array (patent number 6,297,628) has been optimized to allow a greater air gap between the target and the sensor with reduced loss in sensor signal or accuracy. The VF401 has a reduced sensitivity to run-out (shift in sensor position relative to the inside or outside diameter of the ring magnet).
