Through-Hole Latching Hall Effect Magnetic Sensor With Open Drain Output For Embedded And Industrial Applications

The A1220LUA-T Digital Switch Latch Open Drain Hall Effect Magnetic Sensor is a reliable through-hole magnetic sensing device designed for non-contact position detection, rotational sensing, and magnetic switching applications. Built with Hall effect sensing technology, this SIP-3 packaged sensor detects magnetic field polarity changes and provides a stable digital switching output for embedded systems, industrial automation, consumer electronics, and motor-control applications. Its latching operation ensures output stability until an opposite magnetic field polarity is detected.

Featuring an open-drain output configuration and compact through-hole SIP-3 package, the A1220LUA-T is suitable for easy PCB integration and robust electronic designs. The sensor supports low-power operation and contactless switching, helping improve system reliability and reduce mechanical wear in demanding environments. It is widely used in brushless DC motors, speed sensing systems, door-position detection, industrial automation, and magnetic encoder applications.

Key Features

  • Hall Effect Magnetic Detection: Reliable contactless magnetic sensing using Hall effect technology.
  • Latching Digital Switch: Output state remains latched until the opposite magnetic polarity is applied.
  • Open Drain Output: Flexible digital output interface compatible with various logic systems.
  • Through-Hole SIP-3 Package: Easy PCB mounting and soldering for embedded and industrial applications.
  • Digital Switching Operation: Stable ON OFF signal generation for magnetic detection systems.
  • Low Power Consumption: Suitable for battery-powered and portable electronic devices.
