VF401 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.
VF401 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 applications with extreme temperature requirements.
Not damaged by reverse polarity voltages when customer-supplied sense resistor is installed, enhancing protection.
Patented MR bridge optimized for stable sensing of 20- to 50-pole pair ring magnets with improved insensitivity to runout, tilt, and twist.
2-wire digital current output simplifies wiring and interfacing which can reduce total system cost
Enhanced sensitivity, ±7 Gauss typical, allows for larger air gaps (up to 2,5 mm [0.098 in]) and higher pole density (up to
50-pole pairs depending on ring diameter).
VF401 Applications
Speed encoding using a multipole ring magnet
Enhanced accuracy rotational position sensing
Wheel speed sensing
Window lift applications
Speed and direction sensing
Shaft speed encoding using a multipole ring magnet
Enhanced accuracy rotational position sensing
Precision motor speed measurement
Speed control in machine tools
Elevator speed sensing
Speed control in motorized industrial equipment
Shaft speed encoding using a multipole ring magnet
