The **LC20-R06** typically refers to a high-precision, digital laser displacement sensor head, most commonly manufactured by **Keyence** (part of the LC series). These components are designed for non-contact measurement of height, thickness, and position with sub-micron resolution. --- ### 1. Key Technical Specifications The following table outlines the primary electronic and physical characteristics of the LC20-R06 sensor head: | Parameter | Specification | | :--- | :--- | | **Light Source** | Red Semiconductor Laser | | **Wavelength** | 670 nm (Class II) | | **Reference Distance** | 20 mm | | **Measuring Range** | ±3 mm | | **Resolution** | 0.1 µm (Micrometers) | | **Linearity** | ±0.05% of F.S. (Full Scale) | | **Spot Diameter** | Approx. 20 x 40 µm | --- ### 2. Electronic Components & Functionality The LC20-R06 operates as a **triangulation-based** optical system. Here is a breakdown of its internal electronic operation: #### A. Laser Diode (Transmitter) The unit contains a high-stability red semiconductor laser. The electronics drive this diode to emit a concentrated beam that reflects off the target surface. #### B. PSD/CMOS Receiver Unlike standard proximity sensors, the LC20 uses a **Position Sensitive Detector (PSD)** or a high-speed **CMOS array**. * When the target moves, the angle of the reflected light changes. * The internal electronics calculate the exact pixel position where the light hits the receiver to determine distance. #### C. Signal Processing The sensor head sends raw analog/digital data to a separate **Controller Unit** (such as the LC-2400 series). The "R" in the model name often signifies specific cable or connector types designed for low-noise high-speed data transmission. --- ### 3. Application Use Cases Due to its high resolution (0.1 µm), the LC20-R06 is electronically integrated into systems for: * **Semiconductor Inspection:** Measuring wafer warpage or thickness. * **Automotive:** Checking the stroke of valves or disc brake runout. * **Electronics:** Measuring the height of solder paste or small SMD components on a PCB. --- ### 4. Connection Interface The LC20-R06 is not a standalone device; it requires a controller to function. ```yaml System_Layout: Sensor_Head: LC20-R06 (Data Collection) Connection: Multi-pin specialized shielded cable Controller: LC-2400 Series (Power Supply & Signal Processing) Output_Options: - Analog (±5V or 4-20mA) - Digital (RS-232C or PLC Link) ```
