The TDK-Micronas GmbH HAL543SF-K is a unipolar Hall effect sensor from the HAL® 54x series. This digital switch features an open-drain output and is housed in a SOT-89B-1 package (TO-243AA, Variant), suitable for surface mounting. Designed for robust operation, it offers temperature compensation and operates across a wide voltage supply range of 4.3V to 24V. With a maximum output current of 20mA and a supply current of 4.2mA, this component exhibits a typical sensing range with a trip point of 33mT and a release point of 15mT, sensitive to the south pole. Typical applications for this device include automotive systems, industrial automation, and consumer electronics. The HAL543SF-K is supplied on tape and reel.
