Tracking your machine component as it moves along a rotating threaded shaft, such as a spindle or lead screw, these indicators help you adjust machinery with speed and precision.

Often used with servomotors, these transmitters have a mounting hole pattern that fits a three-hole 28 mm BC servomotor face.

In addition to a transmitter, these kits include a 6 1/2-ft. cable and a mounting bracket.

Place against enclosures of rotating equipment to measure speed. Also known as reed tachometers.

Accurate to within ±0.006% of reading, these tachometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Noncontact tachometers emit a beam of light or laser that reflects off a piece of reflective tape attached to the rotating point.

Accurate to within ±0.01% of reading.

These tachometers come with a calibration certificate traceable to NIST that state they have passed a test for accuracy.

Capture high-speed readings from a distance in noncontact mode or use the speed wheel to switch to contact mode.
