Magnetic Sensors - Switches (Solid State)

Unipolar Hall switchNorth-pole activeOpen-drain outputTSOT-23L3.5 V to 24 VRoHS compliant

A 3-lead, medium-sensitivity unipolar Hall switch for north-pole sensing on the marked side of the TSOT-23L package. It operates from 3.5 V to 24 V and provides an open-drain output.

Best for

  • North-pole proximity sensing
  • Compact solid-state switching
  • Interrupter and position sensing circuits

Avoid if

  • The application needs south-pole activation at the marked package face
  • A push-pull output is required without an external pull-up
  • The ambient temperature can exceed 85 °C

Check before use

  • Confirm magnet polarity and mechanical orientation
  • Validate air gap against worst-case BOP and BRP limits
  • Keep output current within ratings
  • Review supply transient protection for harsh environments
