Tamura LA01M Series Hall Effect Current Sensor, part number LA01M021S05. This open-loop, single-channel module accurately measures bidirectional AC/DC currents up to 21A with a nominal sensitivity of 100mV/A. Featuring ±1% accuracy and linearity across a wide frequency range from DC to 400kHz, this sensor is ideal for demanding applications in industrial automation, power supplies, and electric vehicle systems. The module operates from a 4.5V to 5.5V supply with a maximum current draw of 10mA. Its surface mount design and a response time of 1µs facilitate integration into compact designs. The ratiometric voltage output simplifies signal processing. Operating temperature range is -40°C to 90°C. Packaging is supplied in trays.
