30pcs A3144 3144 Hall Effect Sensor, 3Pins. | For High-Temperature Operation

Standard components that work well.

These Hall effect sensors worked out great.I am using them for home position sensors with a neodymium magnet.Easy to wire up to an Arduino and code.

Me ha resultado muy bueno cambiar los desagradables reed switch por estos transistores de efecto Hall. Los reed switch son muy malos porque se magnetizan y terminan NC cuando deberían permanecer NO. En este producto no hay esos efectos malos. Son muy confiables.

Used these to replace a unipolar hall effect sensor with an open-drain output, Allegro A1125LUA-T, but worked perfect for my application even though output of A3144 is open collector.

I was desperate to find more sensors and found these to be perfect replacements.

Replaced an OCH14 hall effect sensor in an ignition circuit of a model engine that lasted for a few years. Soldered one of these in place, lasted about 10 seconds, now output doesn't go low when near the magnet. Replaced with another one from the package and same deal. This chip has the exact same ratings as the OCH14 so shouldn't be a problem for it. Replaced CDI box as well, in case it was drawing too much now, and same problem.

The hall sensors were delivered in proper antistatic packaging. The package contained 30 components as promised and the one component I have tested, so far, works as expected. I would order these parts again.
