product in standard 1x1 form factor product in mini form factor

Do you have a project that could use an inconspicuous HID (human interface device)? Ever wanted to tamper-proof your window alarm (i.e. contact sensors) from teenagers sneaking out or home intruders? Do you have a mechanical switch that keeps failing?

If you answered yes to any of those questions, the TMAG5273 from Texas Instruments could be the solution to your problems. The TMAG5273 is low-power 3D hall-effect sensor that is perfect for detecting and measuring changes in a nearby magnetic field. With a linear, magnetic range configurable to either ±40 mT or ±80 mT and TI's integrated angle calculation engine (CORDIC), the TMAG5273 can be used in various applications:

  • Detecting motor movement
  • Creating a HID (human interface device) (i.e. joysticks, knobs, scroll wheels, etc.)
  • Replacing various mechanical switches (i.e. rotary encoders, contact switches, reed switches, etc.)*

In addition, the included magnetic tamper detection and wake-up/threshold settings can be configured to trigger interrupts through the I2C interface or only with the dedicated interrupt pin.

These products are available in both the standard 1"x1" and mini Qwiic breakout boards. The mini is panel mount compatible for use in enclosures.
