Honeywell Ratiometric Linear Hall Effect Sensor, TO-92

The Honeywell Ratiometric Linear Hall Effect Sensor is a high-performance, miniature solid-state device housed in a compact 3-pin TO-92 package. Designed for versatility, this small sensor is operated by the magnetic field from either a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field, providing precise and reliable measurements for your applications.

This sensor features integrated circuitry that delivers increased temperature stability and sensitivity. Laser-trimmed thin-film resistors ensure high accuracy, with null and sensitivity up to ±3%, alongside excellent temperature compensation. The quad Hall sensing element effectively minimises the effects of mechanical or thermal stress on the output. Additionally, the positive temperature coefficient of sensitivity (+0.02%/°C typical) helps compensate for the negative temperature coefficients of low-cost magnets, ensuring a robust design over a wide temperature range.
