Overview
The HAL 556 and HAL 566 are two-wire Hall-effect sensors produced in CMOS technology, designed for industrial and automotive applications.
Key Features
These sensors operate with supply voltages from 4 V to 24 V, have a junction temperature range from -40°C to 140°C, and are available in SMD and leaded packages.
They feature current output for two-wire applications, operate with static and dynamic magnetic fields, and have built-in overvoltage and reverse-voltage protection.
Switching Behavior
The HAL 556 is a unipolar switching sensor, while the HAL 566 is a unipolar inverted switching sensor, with different magnetic switching points.
Both sensors have active offset compensation, leading to constant magnetic characteristics over a wide supply voltage range.
