About this item

  • These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes.
  • The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points.
  • Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, small signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA.
  • With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The A3141– and A3142– are improved replacements for the UGN/UGS3140–; the A3144– is the improved replacement for the UGN/UGS3120–
  • Superior Temp. Stability for Automotive or Industrial Applications

A little inaccurate but worked well for my application

Not linear as the ad says. They are a 1 for that, but 5 for a dectector.

Just what I ordered. Have not put any of the product into service, yet.

These are okay for a neodymium magnet at a centimeter or so if it's strong. My plan was to build this into a EMF probe so that I could sweep banks of relays and solenoids on solenoid valves at work and make a useful tool out of it. It is not sensitive enough to read an electromagnetic coil even if it's right up against the side of the valve or relay.I'm still giving them five stars because it works and it is as advertised but I was hoping for more sensitivity.

I use these for magnetic field strength sensors, they work great at a very good price.

These linear magnetic sensors work as advertised. They can detect the fields of small neodymium magnets (3mmx1mm) reliably without saturating from a few mm distance. The parts are a little noisy like all integrated hall effect sensors, so it's a good idea to use some analog or digital filtering (or both). I didn't measure the actual noise but I am getting at least 60dB SNR with 1 second of integration time. Drift and gain differences are also "good enough" for my application (as an absolute magnetic rotary sensor). I would buy them again.
