Honeywell Technologies Surface Hall Effect Sensor Digital Interface 3-Pin SOT-89 Package SS543AT

Honeywell SS543AT is a surface-mount Hall Effect Sensor from the SS500 series, featuring a compact 3 mm height SOT-89 package and a 3-pin digital interface. It operates with a wide supply voltage range of 3.8 V to 30 V dc, accommodating diverse electronic and industrial applications requiring reliable magnetic field sensing.

This unipolar sensor detects magnetic fields of a single polarity, providing a stable digital output suitable for position detection and switching tasks. The device is temperature-compensated to function reliably under extreme conditions from -40°C to 150°C, ensuring suitability in harsh industrial and automotive environments.

The sensor draws a steady 20 mA supply current, facilitating predictable power budgeting in system designs. Its surface-mount package with small footprint dimensions (3 mm height, 4.06 mm length, and 1.57 mm width) supports efficient PCB layout in compact electronics.

Applications include rotary position sensing in automation systems, proximity detection in electrical panels and enclosures, motor control circuits for non-contact commutation feedback, and potential use as a limit-switch replacement in mechanical assemblies.

The SS543AT's robust build and extended temperature range make it highly versatile for industrial, electronic, automation, and manufacturing environments requiring accurate and stable magnetic sensing solutions.
