The **KTS-82-R** refers to a high-precision, wireless 3D touch probe commonly used in CNC machining for workpiece alignment and measurement. Below is a detailed breakdown of its electronic components and technical specifications. --- ### 1. Key Electronic Specifications The KTS-82-R operates using infrared transmission to communicate between the probe head and the receiver unit. | Feature | Specification | | :--- | :--- | | **Transmission Type** | Infrared (IR) Wireless | | **Sensing Directions** | ±X, ±Y, +Z | | **Repeatability** | ≤ 1 μm (0.001 mm) | | **Power Supply** | 3.6V Lithium Battery (usually size 1/2 AA) | | **Trigger Force** | XY: ~0.5N; Z: ~2.5N | | **Signal Range** | Up to 5-7 meters | --- ### 2. Core Electronic Components The system consists of two primary electronic assemblies: the **Probe (Transmitter)** and the **Receiver**. #### A. The Probe Unit (Transmitter) * **Kinematic Switch:** The heart of the probe. It uses a three-point contact seat mechanism. When the stylus touches a surface, the circuit is broken (or closed, depending on logic), triggering a signal. * **Signal Processing Circuit:** An internal PCB that debounces the mechanical trigger to prevent "chatter" or false readings. * **IR Emitter LEDs:** High-power infrared LEDs arranged in a 360-degree ring to ensure the receiver can see the signal regardless of spindle orientation. * **Battery Management:** A low-power circuit that keeps the probe in "Sleep Mode" until it receives an "Activation" signal from the receiver. #### B. The Receiver Unit * **IR Sensors:** Photodiode arrays that pick up the infrared pulses from the probe. * **Interface Logic:** Converts the IR pulses into electrical signals (High/Low) compatible with CNC controllers (e.g., Fanuc, Siemens, Heidenhain). * **Status Indicators:** LEDs that show: * **Green:** System Ready/Power On. * **Red:** Probe Triggered (Stylus deflected). * **Yellow:** Low Battery Warning. --- ### 3. Wiring and Interface Logic The receiver typically uses a multi-core cable to connect to the CNC's PLC. ```yaml Standard Wiring Logic: - Brown: DC 24V (Power) - Blue: 0V (Ground) - White: Skip Signal (High/Low) - Connects to G31 input - Green: Battery Alarm (Low Voltage) - Yellow: Error/Interference Signal ``` --- ### 4. Operational Modes 1. **Standby Mode:** The probe is off, consuming micro-amps of power. 2. **Activation:** The CNC sends an IR pulse or a hardware signal to "wake up" the probe. 3. **Measuring:** The probe transmits its status continuously to the receiver. 4. **Timeout:** If no movement or trigger occurs for a set period, the electronics enter sleep mode to conserve battery.
