The **W2PE-51Z-R2/N** belongs to a series of high-density, waterproof connectors, typically manufactured by companies like **Sumitomo** or associated with specific automotive and industrial wire-to-board interconnect systems. Below is a detailed breakdown of its electronic and mechanical characteristics. --- ### 1. General Specifications This part is a **female connector housing** designed for harsh environments where moisture and vibration are prevalent. | Property | Description | | :--- | :--- | | **Component Type** | Connector Housing (Female/Receptacle) | | **Number of Positions** | 51 Pins | | **Gender** | Female (Socket) | | **Waterproof Rating** | IP67 / IP69K (when mated) | | **Mounting Type** | Wire-to-Board / Wire-to-Device | --- ### 2. Key Electronic Features While the housing itself is plastic, its design dictates the electrical performance of the system once the terminals are inserted: * **Current Capacity:** Typically designed for signal-level or low-power currents (approx. 2A to 5A per pin, depending on the terminal gauge used). * **Voltage Rating:** Generally rated for standard automotive DC systems (12V/24V) but capable of handling higher dielectric voltages (up to 1000V AC/1 min) depending on the insulation resistance. * **Contact Resistance:** Engineered to maintain low resistance (<10 mΩ) even under thermal cycling, provided the correct mating male header is used. --- ### 3. Mechanical & Material Construction The "R2/N" suffix often indicates specific material revisions or color coding (typically Black or Natural). * **Seal Mechanism:** Features a circumferential rubber/silicon seal to prevent water ingress. * **Locking Mechanism:** Utilizes a secure lever or push-click locking system to ensure the connector does not decouple during high-vibration scenarios (common in engine compartments). * **Terminal Compatibility:** Compatible with crimp-style sockets. The "51Z" designation refers to the specific grid layout of the 51 contact points. --- ### 4. Typical Applications Due to its high pin density and waterproof nature, this part is commonly found in: 1. **Automotive ECUs:** Main wiring harness connection to the Engine Control Unit. 2. **Industrial Controllers:** Outdoor sensor hubs or heavy machinery control panels. 3. **Marine Electronics:** Navigation and power distribution systems exposed to spray. ---
