Honeywell Technologies Surface Hall Effect Sensor 2.2 V 5.5V, SOT-23, 3-Pin

This hall-effect sensor is a Compact magnetic position-sensing device designed for surface-mounted applications in industrial and electronic systems. It detects magnetic fields digitally and operates within a moderate temperature span, making it suitable for controlled-environment sensing tasks where a small footprint and simple three-pin SOT-23 package are required.

• Operates from 2.2V to 5.5V enabling flexible supply options • Detects both magnetic polarities for simplified orientation sensing • Digital output for straightforward Interface with controllers • Very low supply current consumption of 2.5 mA reducing power draw • Wide ambient temperature range from -40°C to 85°C for varied conditions • RoHS-compliant construction supporting regulatory material limits

• Suitable for contactless position sensing in automation equipment • Ideal for shaft or gear rotation detection in electromechanical assemblies • Used with Compact control boards requiring SOT-23 sensors • Can be used for non-contact switch functions in industrial panels • Suitable for magnetic proximity detection in instrumentation

The device is designed for surface mounting in a SOT-23 footprint and uses three pins for signal, power and ground connections suited to standard reflow assembly.

It provides a digital response to omnipolar magnetic transitions, producing a clear state change when field thresholds are crossed.

The specified operating limits indicate functionality between -40°C and 85°C so reflow profiles should avoid exceeding these temperatures to maintain device integrity.

Yes, the permitted supply range down to 2.2V allows direct connection to many low-voltage logic families without level shifting.
