Honeywell Technologies Surface Hall Effect Sensor -28 V 28V, SOT-23, 3-Pin

This Hall effect sensor provides digital magnetic detection in a Compact surface-mount format, designed for integration where space is limited and omnipolar sensing is required. It operates across a wide bipolar supply range and functions over a broad temperature span, suitable for demanding electronic assemblies. The device is supplied in a SOT-23 package with three electrical connections and meets RoHS standards.

• Low operating current reduces system power draw
• Accepts ±28V supply rails for flexible integration
• Omnipolar magnetic detection enables bidirectional field sensing
• Surface-mount SOT-23 package simplifies automated assembly
• Wide temperature tolerance supports harsh thermal environments

• Suitable for magnetic position sensing in Compact assemblies
• Ideal for small motor commutation feedback systems
• Used with battery-powered systems requiring low current
• Can be used for proximity detection in industrial electronics
• Suitable for signal switching in control and monitoring units

It uses a three-pin arrangement in a SOT-23 footprint for power, ground and digital output.

Its omnipolar response means either north or south pole can trigger the output, easing orientation constraints during assembly.

It is intended for surface mounting onto printed circuit boards using standard SOT-23 reflow soldering processes.

Plan for a supply current of approximately 4.5 mA during normal operation.
