Honeywell Technologies Surface Hall Effect Sensor 3.8 V 30V, Digital, TO-92, 3-Pin

This hall effect sensor provides a compact, digital magnetic switching solution for proximity detection and position sensing in electronic assemblies. It operates as a bipolar magnetic sensor with a digital Interface and is supplied via a low-voltage range suitable for many control systems. The device is designed for surface mounting in a TO-92 style package and is intended for applications requiring a small footprint and dependable switching behaviour across a wide temperature span.

• 3.8V to 30V supply range enabling low-voltage compatibility
• 20mA supply current supporting stable digital switching
• Bipolar magnetic operation allowing detection of north and south poles
• Surface-mount TO-92 package offering Compact integration
• -40°C to 150°C operating span permitting high-temperature deployment

• Can be used for proximity detection in control circuits
• Suitable for speed sensing in small electromechanical systems
• Used with magnetic encoders for position feedback
• Ideal for contactless switching in industrial controls
• Suitable for Compact consumer electronics requiring magnetic sensing

It offers a digital output Interface designed for binary switching applications.

It requires three pins for power, earth and digital output.

The device uses a surface-mount TO-92 style package requiring through-hole-friendly footprint considerations.

It is designed for bipolar sensing so either magnetic pole will actuate the switch.

The operational temperature range extends from -40°C up to 150°C.
