Honeywell 4AV Hall Effect Vane Position Sensors

Honeywell 4AV Hall Effect Vane Position Sensors use a ferrous vane to interrupt magnetic flux between an integrated magnet and sensor, enabling position or speed detection. These sensors support limit switch, tachometer, and synchronization functions, with adjustable ON/OFF times determined by the vane dimensions. The 4AV Vane sensors operate within a temperature range from -40°C to +125°C and a supply voltage range from 4.5Vdc to 26.5Vdc. These components operate at speeds from 0kHz to 100kHz and a maximum output current of ±50mA. Typical applications include door position, plane windscreen wipers, motors, and drives.
