The part number **47LV-2D0YR-M2** refers to a high-performance **Time-of-Flight (ToF) Laser Distance Sensor** (likely from the 47LV series). These sensors are engineered for precision distance measurement, presence detection, and object profiling in industrial automation. --- ### ## Technical Specifications The following table outlines the general electronic and functional characteristics typically associated with this series: | Feature | Specification | | :--- | :--- | | **Sensing Method** | Laser Time-of-Flight (ToF) | | **Light Source** | Class 1 Red Laser (Eye-safe) | | **Supply Voltage** | 10 – 30V DC | | **Output Type** | Push-Pull (NPN/PNP compatible) or Analog | | **Response Time** | < 2 ms (Adjustable depending on mode) | | **Connection Type** | M12 Connector (4-pin or 5-pin) | | **Operating Temp** | -10°C to +50°C | | **IP Rating** | IP67 (Dust tight and water immersion) | --- ### ## Core Electronic Components 1. **Laser Emitter (Class 1):** The unit contains a semiconductor laser diode that emits pulsed infrared or visible red light. Being "Class 1" means it is safe for the human eye under all normal operating conditions. 2. **Receiver Photodiode & ASIC:** At the heart of the device is a high-speed photodiode coupled with an Application-Specific Integrated Circuit (ASIC). The ASIC calculates the time difference between the pulse emission and the reflection reception to determine distance. 3. **Output Circuitry:** * **Digital Output:** Uses a Push-Pull stage, allowing the sensor to interface with both NPN and PNP logic PLC inputs without needing a separate converter. * **Protection:** Integrated reverse polarity protection and short-circuit protection to prevent damage during installation errors. 4. **Configuration Interface:** The "M2" designation often refers to the connector type or specific modulation. Most 47LV models feature an **IO-Link** interface, allowing for digital parameterization, diagnostics, and real-time distance data transmission via the electronic lead. --- ### ## Application Use Cases * **Loop Control:** Measuring the tension or "slack" of material in a production line. * **Level Measurement:** Monitoring the height of solids or liquids in small containers. * **Collision Avoidance:** Used on Automated Guided Vehicles (AGVs) to detect obstacles at a specific range. * **Positioning:** Ensuring components are correctly seated in a jig before a robotic process begins. ---
