Specifications: The AEW632 is a latch-type (bipolar) Hall effect switch in a compact, surface-mount SOT23-3 package. It features an exceptionally wide operating voltage range from 2.3V to 33V, making it compatible with battery-powered systems, 5V logic, and industrial 12V/24V supplies. It draws a low 4mA quiescent current. The device has a symmetrical operating point of 30 Gauss (South pole) and a release point of -30 Gauss (North pole), enabling precise bipolar latching action. It is rated for harsh environments with an operating temperature range of -30°C to 120°C.

Application Scenarios: This switch is ideal for precise rotation counting and speed measurement. It is extensively used in brushless DC (BLDC) motor commutation for fans, pumps, and small appliances. It is also perfect for flow meters, gear tooth sensors (e.g., in automotive transmissions and industrial encoders), and as a contactless replacement for mechanical reed switches in vending machines and tamper-proof systems, offering high reliability and long life.
