WENTAO RT-40 2.4GHz Radio Touch Trigger Probe System for Large CNC Machining Centers

### WENTAO RT-40 2.4GHz Radio Transmission Touch Probe System

The product comes with a set of measuring probes, tool holders, and extension bars.

The WENTAO RT-40 is a next-generation 3D radio workpiece measurement system designed specifically for large CNC machining centers, gantry mills, and complex multi-tasking machine tools. Built for environments where optical line-of-sight signal transmission is frequently obstructed, the RT-40 utilizes advanced 2.4 GHz Frequency Hopping Spread Spectrum (FHSS) radio technology. Operating alongside the RRI integrated machine interface/receiver, it delivers reliable, high-precision automated workpiece alignment, edge-finding, and dimensional inspection across long working distances.

### Key Features & Advantages

* Advanced 2.4 GHz FHSS Technology: Operates on the global 2400 MHz to 2525 MHz frequency band with dynamic frequency hopping, effectively preventing radio interference and enabling multiple systems to operate simultaneously in the same workshop.

* Non-Line-Of-Sight Transmission: Radio signals penetrate small gaps, machine enclosures, and structural blockages over an extended operating range of up to 10 meters.

* High Repeatability & Sub-Micron Resetting: Features a precision 3-point hybrid trigger mechanism delivering a unidirectional repeatability of 1.00 µm 2σ and a self-resetting accuracy of < 1 µm.

* Multi-Probe Capability: Up to 4 radio probes or tool setters can be paired with a single RRI interface, allowing versatile combinations on a single machine tool.

* Flexible Activation & Sleep Modes: Supports customizable Radio On/Off M-codes, Timeout Delay, and intelligent Sleep Modes (waking up every 5s/30s) to significantly preserve battery power.

* IPX8 Extreme Sealing Defense: Engineered with a heavy-duty IPX8 waterproof structure and IK01 glass window to withstand continuous coolant sprays, oils, and flying metal chips.

* Dual Power Compatibility: Operates on standard 2x AA 1.5V alkaline batteries or high-capacity 2x AA 3.6V Lithium Thionyl Chloride (LTC) batteries, yielding up to 1,710 hours of continuous use (LTC).
