Honeywell Series SS Hall Effect Sensor, 305 gauss sensitivity, 3V to 24V supply voltage - SS349RT

This Hall-effect sensor provides a compact, digital magnetic switch for surface-mounted PCB implementations. Designed for detection of unipolar magnetic fields, it operates across a wide supply range and is intended for applications requiring small-footprint sensing with industry-standard package compatibility.

Features and Benefits:

• Digital output enables straightforward logic-level interfacing
• Low supply current reduces power draw in battery systems
• Wide supply voltage supports flexible circuit designs
• Operates across extreme temperatures for harsh environments
• SOT-23 surface package allows automated PCB assembly

Applications

• Suitable for magnet position sensing in Compact assemblies
• Ideal for low-power portable devices requiring magnetic detection
• Used with motor-control boards for non-contact switching
• Can be used for tamper detection on small enclosures
• Used for proximity sensing on densely populated PCBs

What supply voltage range can it tolerate?

It accepts voltages from 3V up to 24V.

How many electrical connections are required for installation?

The component uses three pins for power, ground and digital output.

What magnetic threshold triggers the switch?

The device responds at approximately 305 gauss sensitivity.

What mounting style is suitable for automated production?

It is designed for surface-mount placement in an SOT-23 package.

What environmental extremes can it withstand?

The unit functions between -40°C and 150°C.
