Honeywell Series SM Hall Effect Sensor, 3V Minimum Supply Voltage, 24V Maximum Supply Voltage - SM351RT


This hall effect sensor is a compact, surface-mount position sensor that detects magnetic fields for position sensing in electronic assemblies. It operates across a wide supply range suitable for varied low-voltage systems and is built for continuous use within a specified ambient temperature span. The device uses magnetoresistive technology and is supplied in a SOT-23 package for board-level integration.

Features and Benefits:


• Low supply consumption of 5mA reduces system power draw
• Fast 10μs response enables Rapid position detection
• Omnipolar magnetic sensing allows flexible orientation detection
• High sensitivity of 11 gauss improves detection of weak fields
• RoHS-compliant construction supports lead-free assembly processes

Applications


• Suitable for Compact position feedback in motor controllers
• Ideal for non-contact switch detection in consumer devices
• Used with low-voltage control circuits from 3V to 24V
• Can be used for rotational position sensing in small actuators
• Suitable for space-constrained surface-mount assemblies

What mounting style does it require?


It is intended for surface mounting on PCBs and comes in a SOT-23 package.

What environmental temperatures can it tolerate?


It is rated to operate down to -40°C and up to 85°C.

How many electrical connections are provided?


There are three pins for power, ground and signal output.

What is the device height for enclosure planning?


The vertical profile measures 1.6 mm for clearance calculations.

Does it conform to automotive standards?


It is not specified for automotive-grade standards but is RoHS-compliant.
