Digital speed tachometer + blue LED CF5135C-Z

The LED CF5135C-Z digital tachometer with blue display is a precision tool for measuring rotational speed. The results are displayed on the LED display in units of revolutions per minute (RPM). The device uses an NPN Hall sensor that works with a magnet mounted on a rotating component, making it ideal for measuring the speed of shafts, fans and other rotating parts.

Make sure that the magnet is facing the sensor with the correct pole. If the display shows 0000 or there is no message, reverse the magnet. Connecting the tachometer requires the following wires: black (output signal), brown (power +) and blue (power -). Power supply to the unit is via the wires: black (-) and red (+).
