Infrared transmission

The reliable infrared signal transmission of these touch probes reduces cabling in hard-to-access machines. Infrared transmission is ideal for compact machines.

Long battery life

The smart standby function of the HEIDENHAIN workpiece touch probes enables a battery life of approx. 800 hours, thereby reducing downtime from frequent battey changes. Batteries can be changed quickly and without tools.

High stylus variety

HEIDENHAIN offers the right stylus for any application, with a variety of ball diameters and lengths. Changing the styli couldn't be easier: all of them are fastened to the TS workpiece touch probes via an M3 thread. 

Long-lasting accuracy

Even after five million probing cycles, the HEIDENHAIN workpiece touch probes are still highly accurate: with a probing repeatability of down to 2 σ ≤ 1 Âµm at a probing speed of 3 m/min, these touch probes deliver reliable measurements even after prolonged use.
