DOP40-PRO Infrared CNC Touch Probe from Qidu Probing is designed for automated workpiece setup, positioning and on-machine measurement in CNC machining centers. Using infrared optical transmission, the probe communicates with a dedicated receiver to transfer measurement signals to the machine control system.
With specified repeatability below 1 μm using a 50 mm stylus at probing speeds of 50–200 mm/min, the DOP40-PRO supports repeatable contact measurements when correctly installed and calibrated. Its 360° optical transmission envelope and operating range of up to 5 m provide flexibility for receiver positioning within the machine enclosure, subject to suitable optical visibility.
The probe features IP68-rated protection, a compact 40 mm body diameter and battery-powered operation using two 14250 lithium batteries.
Developed for CNC machine-tool applications, the DOP40-PRO can be used for workpiece referencing, feature measurement and setup verification. Qidu also provides installation guidance and technical assistance for CNC integration, measurement macros and troubleshooting.
