Product Description
Allegro Microsystems A1120LUA-T Through Hole Hall Effect Sensor provides precision unipolar magnetic sensing with excellent temperature stability and stress resistance, enabled by chopper stabilisation technology. It operates with supply voltages ranging from 3 V up to 24 V, making it suitable for various electronic control and automotive applications.
This sensor integrates a voltage regulator, Hall voltage generator, small-signal amplifier, Schmitt trigger, and open-drain output capable of sinking up to 25 mA. Its built-in short circuit protection enhances durability and safety during operation.
Designed for through hole mounting in a compact 3-pin SIP package, the device measures 4.09 mm in length, 3.02 mm in height, and 1.52 mm in width, making it ideal for PCB integration with minimal space requirements. It withstands harsh environments with an operating temperature range from -40°C to 150°C.
Its fast 25 μs response time ensures prompt switching in presence of a south pole magnetic field, with the output turning on for south pole presence and off upon removal. The sensor complies with AEC-Q100 automotive standards, highlighting its suitability for automotive electronics and demanding industrial sensor applications.
Applications of the A1120LUA-T include industrial motion sensing, position sensing, brushless DC motors, and non-contact switching used across manufacturing, automotive, and consumer electronics sectors.
