The Radio transmission probe operates through radio signal transmission, it employs 2.4GHz radio frequency hopping transmission technology, which can avoid any potential interference and transmission dead zones.

Being switched-on and switched-off without requiring M-code control, it automatically measures the origin of the workpiece and dimensions after machining at high speed and with high precision. Mainly, it allows machine tools and robots to reduce setup time, prevent machining defects, improve cycle time, and eliminate dependence on skilled operators and jigs.

It maintains excellent reliability even in high-density radio frequency environments. Therefore, the wireless probe is an ideal choice for operation on all size of machine.
