The part number **47LAC-2D2BG-R** refers to a high-performance **Push-Pull Circular Connector**, typically manufactured by companies like **ODU** (Mini-Snap series) or compatible high-end connector specialists. These connectors are designed for medical, industrial, and test-and-measurement applications where a secure, compact, and shielded connection is required. --- ### Technical Specifications Below are the primary technical characteristics of this specific component: | Feature | Specification | | :--- | :--- | | **Series** | L Series (Circular Push-Pull) | | **Housing Material** | Chrome-plated Brass (Ruggedized) | | **Configuration** | 2-Contact (or 2-pole) | | **Gender** | Receptacle (Female body, typically Panel Mount) | | **Termination Type** | Solder or PCB (depending on exact suffix) | | **Ingress Protection** | IP50 (Standard) to IP68 (when mated/sealed) | | **Shielding** | 360° EMC Shielding | --- ### Key Components & Features 1. **Push-Pull Locking Mechanism:** The "L" in the part number often indicates the locking style. It allows for quick mating and prevents accidental disconnection. The connector can only be released by pulling back the outer sleeve. 2. **Coding/Keying (2D2):** The "2D2" portion of the code usually refers to the **mechanical keying**. This prevents mis-mating by using specific internal grooves. It ensures that only the correct plug can be inserted into this specific receptacle. 3. **Gold-Plated Contacts (BG):** The "BG" suffix typically denotes the contact plating. Gold is used to ensure high conductivity, prevent oxidation, and maintain low contact resistance over thousands of mating cycles. 4. **Environmental Durability (-R):** The "-R" often stands for **RoHS Compliant**, indicating the part meets environmental standards regarding hazardous substances (Lead-free). ### Common Applications * **Medical Devices:** Patient monitoring, ultrasound equipment, and surgical tools. * **Data Acquisition:** High-speed sensors and testing rigs. * **Military/Aerospace:** Portable communication systems where weight and space are critical. ---
