Description

The SS566AT from Honeywell is a versatile, board-mount digital Hall-effect sensor IC that responds to the magnetic field from a permanent magnet or electromagnet. Its bipolar design requires both a south and north pole to operate, making it ideal for precise position sensing in motion control applications. The device provides a digital output signal that switches in response to the applied magnetic flux density within its specified range.

Engineered for reliability in harsh environments, the sensor maintains stable operation across an extended industrial temperature range from -40°C to 150°C. Its 3 Vdc capability supports modern low-power designs, promoting system-level energy efficiency while the SOT-89-3 package enables compact, cost-effective assembly in space-constrained applications.

Frequently Asked Questions

What is the operating voltage for the Honeywell SS566AT sensor?

The Honeywell SS566AT is designed for low-voltage operation at 3 Vdc. This makes it suitable for battery-powered applications and modern digital logic systems where energy efficiency is a priority. Ensure your power supply is stable within this specification for reliable sensor performance.

How does the bipolar operation of this Hall-effect sensor work?

A bipolar Hall-effect sensor like the SS566AT requires both magnetic polarities to operate. Its output switches on when a south pole of sufficient strength (100-180 G) is presented and switches off when a north pole is presented. This makes it ideal for sensing alternating magnetic fields in rotary encoders or reciprocating motion.

What is the maximum load the sensor output can drive?

The SS566AT output can sink up to 20 mA. This allows it to directly drive LEDs, small relays, or serve as a logic-level input to microcontrollers (like Arduino or ESP32) without requiring an additional buffer or transistor in many cases. Always check the connected load's current requirements.

Can this sensor be used in high-temperature environments?

Yes, the SS566AT is rated for an extended operating temperature range from -40°C to 150°C. This thermal robustness makes it suitable for applications in under-hood automotive systems, industrial machinery near heat sources, and other demanding environments where consistent magnetic sensing is required.
