The **HVS-Z3-R** refers to a high-speed, high-precision laser displacement sensor head, typically part of the **KEYENCE HVS series**. These electronic components are designed for automated visual inspection and measurement in industrial environments. --- ### 1. Key Electronic Components & Technologies The HVS-Z3-R utilizes specialized circuitry to achieve sub-micron resolution. | Component | Description | Function | | :--- | :--- | :--- | | **GaAs Laser Diode** | Gallium Arsenide semiconductor laser. | Projects a stable light beam onto the target surface. | | **CMOS Image Sensor** | High-speed complementary metal-oxide-semiconductor. | Captures the reflected light pattern at high frame rates. | | **Processor (DSP/FPGA)** | Digital Signal Processor or Field Programmable Gate Array. | Calculates distance based on the position of light on the sensor. | | **Custom Lens System** | Aspherical glass or plastic lenses. | Focuses the laser and ensures minimal spherical aberration. | --- ### 2. Technical Specifications Below are the core electronic and performance specifications for the HVS-Z3-R model: | Feature | Specification | | :--- | :--- | | **Reference Distance** | 30 mm | | **Measuring Range** | ±5 mm (25 to 35 mm) | | **Light Source** | Red Semiconductor Laser (Wavelength: 655 nm) | | **Laser Class** | Class 2 (IEC60825-1) | | **Sampling Cycle** | Up to 20 µs (High-speed mode) | | **Repeatability** | 0.1 µm | --- ### 3. Electronic Interface and Integration The sensor head itself does not work in isolation; it must be connected to a dedicated controller (typically the **HVS-C series**). * **Connection Cable:** Uses a high-flex, shielded multi-core cable to prevent Electromagnetic Interference (EMI) from affecting the analog signals. * **Signal Processing:** The raw data from the CMOS sensor is digitized within the head or the controller to provide NPN/PNP outputs or analog voltage/current signals (e.g., 4-20 mA). * **Triggering:** Features an electronic trigger input for synchronized measurement with PLC (Programmable Logic Controller) systems. ### 4. Application Logic The electronic system operates on the principle of **Laser Triangulation**: 1. The emitter sends a laser pulse. 2. The light reflects off the object. 3. The receiver lens focuses the reflection onto a specific pixel on the CMOS sensor. 4. The internal electronics calculate the angle of the reflection to determine the exact distance. ---
