IR Touch Probe (JPM50/JPM60)

The optical transmission probe is an ultra-compact design probe that operates by optical signal transmission, which used for workpiece set-up inspection on small and medium machining centers.

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.

FAQ of IR CNC Touch Probe

What is the difference between IR and radio (RF) CNC touch probes?

IR (Infrared): Line-of-sight, short range, no interference, ideal for small CNC machines.
RF (Radio Frequency): Non-line-of-sight, long range, strong anti-interference, suitable for large / 5-axis CNC machines.

Is the IR CNC Touch Probe compatible with my CNC machine?

Yes, the touch probe is designed to be compatible with most mainstream CNC controllers such as FANUC, Siemens, Mitsubishi, Brothers, and others.

What is the measurement accuracy of the CNC touch probe?

The repeatability of the CNC touch probe is ≤ 1 μm.

How is the touch probe powered?

The probe uses replaceable lithium batteries with low power consumption design, ensuring long service life.

Does coolant or chips affect the probe performance?

The probe features a sealed IP68-rated design, making it highly resistant to coolant, oil, and metal chips commonly found in CNC environments.
For infrared touch probe, if chips adhere to the probe or receiver surface, they must be cleaned promptly to prevent blockage of optical signals.

Is installation complicated?

No, the touch probe is designed for easy installation. Detailed manuals and technical support are provided to ensure reliable operation.

Can the stylus be customized?

Yes, Customized stylus is available.
