The **W2PE-54WF-R** is a specific electronic connector component, typically part of a high-density, high-performance interconnect series used in automotive or industrial electronics. It is primarily identified as a **Wire-to-Board (W2B)** header connector. --- ### 1. General Specifications Based on standard industry nomenclature for this series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Right Angle Header (Male) | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (depending on sub-variant) | | **Pitch** | Typically 2.0mm or 2.54mm (Series dependent) | | **Number of Pins** | 54 Positions | | **Contact Material** | Copper Alloy with Tin or Gold Plating | | **Housing Material** | High-temperature Thermoplastic (UL94V-0) | --- ### 2. Key Components and Design The "W2PE" series is designed for reliability in harsh environments. Below are the electronic parts and design features: #### A. Contact Pins (Terminals) * **Plating:** Usually features tin plating over nickel to prevent oxidation and ensure stable electrical conductivity. * **Current Rating:** Typically supports between 2A to 5A per contact, depending on the wire gauge used in the mating female connector. #### B. Retention Features * **Locking Mechanism:** Often includes a friction lock or a positive latching mechanism to prevent accidental disconnection due to vibration (common in automotive applications). * **Solder Tabs:** Includes metallic reinforcement tabs on the sides to provide mechanical strength to the PCB bond, preventing the connector from being ripped off during manual plugging. #### C. Polarized Housing * The plastic body is "keyed," meaning the mating connector can only be inserted in the correct orientation, preventing short circuits or pin damage. --- ### 3. Applications This part is commonly found in the following electronic assemblies: 1. **Automotive ECUs:** Connection points for Engine Control Units. 2. **Infotainment Systems:** Data and power routing for dashboard displays. 3. **Industrial Automation:** Interface boards for PLC (Programmable Logic Controllers). --- ### 4.
