Honeywell Through Hole Hall Effect Sensor, TO-92, 3-Pin

The Honeywell VG481V1 contains a dual peak detecting circuit that is coupled with a hall-effect element to detect the speed of a ferrous gear tooth target wheel. A biasing magnet provides a changing magnetic field as the target wheel moves past the senor IC. It consists of a voltage regulator, clock/oscillator, Hall element, amplifier, internal peak/valley track and hold circuits, comparator, and open collector output stage. The . The sensor IC is protected from abnormal operation at low voltage by a power-on rest circuit. The output circuitry contains short circuit protection.
