Sensors

Latching Hall devices require alternating N and S poles across the sensing face; the output follows the pole transition — delivering stable magnetic switching for BLDC commutation, speed/direction detection and position memory.

Different sensor types have completely different parameters, so every sub-category has its own page and its columns follow that sub-category actual specification. Click a group name for the group overview, or a specific category for the full parameter table.

Hall switch3 sub-categories · 46 in stock

Latching Hall IC15 in stockThe output only changes state when the field polarity switches from N to S, so the state latches — a stable switch for BLDC commutation and speed / direction detection. Dual-Channel Hall Effect Output8 in stockOne latching device delivers two channels of magnetic information — speed + speed or speed + direction — for speed and direction sensing, encoder disk detection and actuator travel feedback. Omnipolar / Unipolar Hall IC23 in stockOmnipolar types trigger on either the N or S pole and accept any magnet orientation; unipolar types respond only to a specified pole. Used for lid open/close, access control and position detection.
