Circuit Protection Electronics Hall-effect Hall-effect protocol protocol Sensor sensor SENT SENT

TDK CORP Micronas HAL 1890 linear Hall-effect sensor is programmable and supports the latest SENT protocol according to SAE J2716 Rev. 4. Device comes with digital output signal supervision and is as small, robust and cost-effective as firm’s HAL 188x variants. Device is an optimal system solution to measure small angles of up to 90° or linear displacements of a few millimeters in harsh environments. The sensor supports various SENT data frame formats (H.2 and H.4), as well as error signal transmission on Fast and Slow channels.

Device is qualified according to AEC-Q100 and is housed in an industry standard 3-pin TO92-UA package, lead free, with matte tin lead frame plating. It comes with two pin configurations: an in-line version with 1.27 mm pin-to-pin spacing or, alternatively, a spread-pin version with 2.54 mm pin-to-pin spacing, which is better suited for welding.
