Based on the part number provided, this appears to be a specialized industrial automation component, specifically a **Safety Light Curtain Receiver** from the **M2SES** series (likely manufactured by companies like Reer or similar safety sensor specialists). The suffix **"CE"** denotes compliance with European Health, Safety, and Environmental protection standards. --- ### 1. Technical Specifications The model name indicates a specific configuration of height, resolution, and functional role within a safety system. | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Receiver (R) | Paired with an Emitter to form a light grid. | | **Resolution** | 30mm - 40mm (Typical) | Usually designed for "Hand Detection." | | **Protected Height** | 600mm (Approx.) | The "6E" often denotes the number of optical modules or height. | | **Safety Type** | Type 2 / SIL 2 | Suitable for medium-risk machine safeguarding. | | **Operating Voltage** | 24 VDC ± 20% | Standard industrial power supply requirement. | | **Output Type** | 2 PNP Static Outputs | Short-circuit protected safety outputs (OSSDs). | --- ### 2. Key Electronic Features #### A. OSSD Outputs (Output Signal Switching Devices) The unit features two independent self-monitoring semiconductor outputs. These are designed to detect: * Internal electronic failures. * Short circuits to the power supply. * Cross-circuits between the two outputs. #### B. Synchronization The receiver synchronizes with the emitter optically. It requires a clear line of sight to establish the safety field. If any beam is interrupted, the electronic circuit transitions the OSSDs to the **OFF** state within milliseconds. #### C. Integrated Status LEDs The electronic faceplate typically includes: * **Red LED:** Break in beams / System Lockout. * **Green LED:** Guarding active / All beams clear. * **Yellow/Amber LED:** Weak signal or misalignment warning. --- ### 3. Connection Pinout (Typical M12 Connector) Most industrial light curtains of this class use an M12 5-pin or 8-pin connector. | Pin | Function | Color (Standard) | | :--- | :--- | :--- | | 1 | +24VDC | Brown | | 2 | OSSD 1 (Output) | White | | 3 | 0V (GND) | Blue | | 4 | OSSD 2 (Output) | Black | | 5 | FE (Functional Earth) | Gray | --- ### 4. Application Environment * **Response Time:** Extremely fast (usually < 20ms) to ensure the machine stops before a human limb reaches the hazard. * **Safety Rating:** Designed for Category 2 applications according to EN ISO 13849-1. * **Protection Rating:** Usually IP65 or IP67, making the electronics resistant to dust and water splashes.
