The **RTS-3D3-R/E** is a high-precision, wireless 3D touch probe system primarily used in CNC machining centers for workpiece alignment and inspection. It is manufactured by **Renishaw** (or compatible providers) and utilizes optical infrared transmission. --- ### Core Electronic Components and Specifications The device integrates several sophisticated electronic subsystems to ensure sub-micron repeatability and reliable signal transmission in harsh industrial environments. #### 1. Sensing Mechanism (The Trigger) The probe uses a kinematic resistive design. When the stylus touches a surface, the internal mechanical structure deflects, breaking an electrical circuit. * **Repeatability:** Typically < 1.0 $\mu$m. * **Trigger Force:** Pre-set internally to ensure consistent signal generation. #### 2. Transmission Module (Infrared) Since this is the "R/E" (Receiver/Emitter) variant, it relies on line-of-sight infrared communication to send data back to the CNC controller. * **Signal Type:** 360° infrared optical transmission. * **Range:** Usually up to 6–10 meters depending on the receiver. * **Channels:** Supports multiple channels to prevent interference with other probes in the same workshop. #### 3. Power Management * **Battery Type:** Typically powered by 2x LS14250 (3.6V Lithium) or equivalent batteries. * **Standby Mode:** Includes low-power electronic "sleep" states to prolong battery life (often lasting > 6 months under normal usage). --- ### Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Transmission Type** | Infrared (Optical) | | **Sensing Directions** | 5-way: ±X, ±Y, +Z | | **Operating Voltage** | 3.0V to 3.6V DC | | **Signal Transmission Range** | Up to 10m (33 ft) | | **IP Rating** | IP68 (Electronic components sealed against coolant/dust) | | **Receiver Compatibility** | Works with OMI-2, OMI-2T, or OSI/OMM-2 receivers | --- ### Electronic Connectivity & Integration The probe interacts with the CNC machine's PLC (Programmable Logic Controller) through an interface unit. ```mermaid graph LR A[Stylus Contact] --> B[Internal PCB] B --> C[IR Emitter] C -- Optical Signal --> D[Machine Receiver] D --> E[CNC Controller/PLC] ``` 1. **Status LEDs:** The probe body features circular LEDs that change color (Green/Red) to indicate battery status, trigger state, and signal strength. 2. **Logic Logic:** The electronic output is usually "Fail-Safe," meaning the CNC will stop (E-stop) if the signal is lost or the battery dies to prevent a crash. ---
