The **KTS-3D-R/BL** refers to a high-precision, 3D wireless edge finder (frequently used in CNC machining). These devices are critical for determining workpiece zero points and measuring dimensions. Below is a breakdown of the electronic components and technical characteristics that define this device. --- ### 1. Core Electronic Components | Component | Description | Function | | :--- | :--- | :--- | | **Trigger Sensor** | High-sensitivity kinematic contact switch. | Detects micron-level displacement when the stylus touches a surface. | | **Infrared (IR) Transmitter** | Optical communication diode. | Sends the trigger signal wirelessly to the machine receiver. | | **Integrated Circuit (IC)** | Low-power microcontroller (MCU). | Processes the physical trigger signal into a digital pulse. | | **Power Management** | Battery-operated circuit (usually 3.6V Lithium). | Ensures long standby times and stable voltage for consistent repeatability. | | **LED Status Indicator** | RGB or Single-color LED. | Provides visual feedback on battery life and trigger status. | --- ### 2. Technical Specifications These electronic parts work together to achieve the following performance metrics: * **Sensing Directions:** ±X, ±Y, +Z * **Trigger Repeatability:** < 0.001 mm (1 micron) * **Signal Transmission:** Infrared (BL stands for the optical/wireless link variant). * **Protection Rating:** IP68 (Electronic internals are sealed against coolant and dust). --- ### 3. How the Electronics Function (Workflow) 1. **Contact:** The tungsten carbide ball at the end of the stylus touches the workpiece. 2. **Deflection:** The internal kinematic seat (usually three pins resting on six balls) is slightly disturbed. 3. **Circuit Break:** The disturbance breaks an electrical circuit within the probe head. 4. **Signal Conversion:** The internal PCB converts this "break" into a coded infrared pulse. 5. **Transmission:** The IR diode flashes the signal to the receiver mounted on the CNC machine cabinet. 6. **Machine Input:** The receiver converts the light pulse into an electrical signal (usually 24V DC) for the CNC controller (Fanuc, Siemens, Haas, etc.). --- ### 4. Comparison: Wired vs. Wireless (R/BL) | Feature | KTS-3D (Wired) | KTS-3D-R/BL (Wireless) | | :--- | :--- | :--- | | **Connection** | Physical Cable | Infrared / Radio Link | | **Power Source** | From Controller | Internal Battery | | **Flexibility** | Limited by wire length | Full range of tool changer movement | | **Signal Lag** | Zero | Minimal (Microseconds) | ---
