Frequently Asked Questions

What's the difference between Hall and AMR magnetic sensors?

Hall is lower cost, good for general position/speed. AMR has higher sensitivity and better stability, better for precision angle or weak field applications.

Do I need a magnet to use Honeywell magnetic sensors?

Yes, most require an external magnet (or ferrous target like gear teeth) to generate the field for detection.

Can they work in high temperature or dusty environments?

Most models work from -40°C to 125/150°C. Non-contact design is dust- and vibration-resistant, suitable for industrial/automotive harsh conditions.

Are they compatible with 3.3V or 5V systems?

Many support both 3.3V and 5V supply. Check datasheet for exact voltage range and output type (analog/digital).

How long do Honeywell magnetic sensors last?

Solid-state, no moving parts - typical lifetime >10 years or billions of operations, much longer than mechanical switches.

Can they detect both speed and direction?

Some dual-channel or quadrature output models can detect both speed and rotation direction. Single-channel usually only speed/presence.

Are these sensors sensitive to EMI or electrical noise?

Honeywell designs include noise filtering and EMC protection, but proper grounding and shielding are still recommended in noisy environments.

What's the typical response time?

Usually microsecond-level response, fast enough for motor commutation, high-speed counting, and real-time position control.

Do you have AEC-Q100 qualified parts for automotive?

Yes, many series (like SS/SM/SL) are AEC-Q100 qualified, suitable for automotive powertrain, chassis, and body applications.
