The **MPCJR-RV** is a specialized electronic component, typically classified as a **Modular Jack (RJ45)** connector. These parts are fundamental in networking and telecommunications hardware, designed to provide a physical interface for data transmission. --- ## 1. Component Overview The MPCJR-RV is a right-angle, shielded or unshielded (depending on the specific variation) modular jack. It is designed for **PCB (Printed Circuit Board)** mounting. ### Key Specifications | Feature | Specification Details | | :--- | :--- | | **Connector Type** | RJ45 (8P8C - 8 Positions, 8 Contacts) | | **Mounting Type** | Through-hole, Right Angle (90 degrees) | | **Termination** | Solder | | **Housing Material** | High-temperature Thermoplastic (UL 94V-0) | | **Contact Plating** | Gold over Nickel (usually 30µ" to 50µ" gold) | --- ## 2. Technical Features The "RV" suffix often denotes a specific orientation or internal configuration (such as "Reverse" or "Vertical" variations depending on the manufacturer's catalog). ### A. Electrical Performance * **Voltage Rating:** Typically 125 VAC RMS. * **Current Rating:** 1.5 Amperes. * **Contact Resistance:** 20mΩ Max. * **Insulation Resistance:** 500MΩ Min @ 500V DC. ### B. Mechanical Durability * **Mating Force:** 22.5N Max. * **Retention Strength:** 7.7kg between jack and plug. * **Durability:** Minimum 750 mating cycles. --- ## 3. Pinout Configuration For a standard 8P8C (RJ45) modular jack like the MPCJR-RV, the pinout follows the standard Ethernet alignment: ```text Pin 1: TX+ (Transmit Data +) Pin 2: TX- (Transmit Data -) Pin 3: RX+ (Receive Data +) Pin 4: Unused/Reserved Pin 5: Unused/Reserved Pin 6: RX- (Receive Data -) Pin 7: Unused/Reserved Pin 8: Unused/Reserved ``` --- ## 4. Typical Applications These connectors are widely used in industrial and consumer electronics: 1. **Network Switches/Routers:** Providing Ethernet ports for LAN connections. 2. **Industrial Controllers:** Used in PLCs (Programmable Logic Controllers) for Modbus or EtherCAT communication. 3. **Embedded Systems:** Integrating internet connectivity into custom PCB designs. 4. **Telecommunications:** Connection points for VoIP phones and digital PBX systems.
