The **OMD8000-R2100-R2-2V15** is a high-performance 2D LiDAR sensor manufactured by Pepperl+Fuchs. It utilizes **Multi-Ray Scan (MRS)** technology to provide 2-dimensional measurements. Below is a detailed breakdown of its electronic components, interface specifications, and internal logic. --- ### 1. Core Electronic Specifications The sensor operates on a Time-of-Flight (ToF) principle, utilizing infrared laser diodes and high-speed processing electronics. | Feature | Specification Details | | :--- | :--- | | **Operating Voltage** | 10 ... 30 V DC | | **Current Consumption** | < 100 mA at 24 V (no load) | | **Light Source** | Infrared Laser Diode (905 nm) | | **Laser Class** | Class 1 (Eye-safe) | | **Sampling Rate** | 250 Hz (Standard) | | **Angular Resolution** | 0.5° | --- ### 2. Internal Electronic Architecture The device consists of several critical electronic sub-systems: #### A. The Emitter & Receiver Array Unlike traditional LiDARs that use a spinning mirror, the R2100 series often utilizes multiple LED or Laser emitters arranged in a fan shape. This reduces mechanical wear and increases electronic reliability. * **Emitter:** 11 infrared emitters providing a 110° field of view. * **Receiver:** A high-sensitivity photodiode array synchronized with the pulsing circuit. #### B. Signal Processing Unit * **ASIC/FPGA:** Used for calculating the "Time-of-Flight" (ToF). It measures the nanosecond delay between the light pulse emission and the reflection reception. * **Filtering Logic:** Includes electronic filters to suppress ambient light interference and multi-echo interference. #### C. Output Interface (The "2V15" Designation) The suffix **2V15** refers to the specific wiring and output configuration: * **Connector Type:** M12 x 1 connector, 5-pin. * **Switching Outputs:** Typically features 2 push-pull (npp) outputs. * **Functionality:** These outputs are short-circuit protected and reverse polarity protected. --- ### 3. Pinout Configuration (M12 Connector) The electronic connection is standardized for industrial PLC integration. | Pin | Wire Color | Function | Description | | :--- | :--- | :--- | :--- | | 1 | Brown | L+ | +24V Supply | | 2 | White | Q2 | Switching Output 2 | | 3 | Blue | L- | 0V / Ground | | 4 | Black | Q1 | Switching Output 1 | | 5 | Gray | Service | Diagnostic/Configuration Input | --- ### 4. Environmental Protection Electronics The sensor includes internal protection circuitry to ensure stability in industrial environments: * **EMC Protection:** Designed to withstand electromagnetic interference from motors and heavy machinery (EN 60947-5-2). * **Thermal Management:** Internal temperature compensation to prevent distance drift caused by diode heating. ---
