For a typical N35-grade neodymium magnet 3 mm in diameter, the 2.7 mT trip corresponds to an air-gap of roughly 8–10 mm — the release at 0.3 mT extends the release gap to about 20 mm, so the output stays low through a wide approach and only resets when the magnet moves well away. Because the device is omnipolar, either pole triggers the same output state — no need to track magnet orientation in the assembly. The push-pull output drives directly to the supply or ground rail without an external pull-up resistor, saving one component per sensor node. ## Temperature range and deployment environments The magnetic thresholds shift with temperature — the datasheet typical curve shows the trip point varies by roughly ±10% across the full range — so a design that closes the magnet gap by an extra 1–2 mm at room temperature holds margin at the hot end.","metaTitle":"TMAG5231A1CQDMRR Hall Switch, 1.65 V, Omnipolar, Active","metaDescription":"Texas Instruments TMAG5231A1CQDMRR low-power omnipolar Hall-effect switch. 1.65 V supply, ±2.7 mT trip, -40 to +125 °C.
