The **M2PP-94R-R/UL** is a specific electronic component typically categorized as a **modular jack or connector**, often used in telecommunications and networking equipment. Below is a detailed breakdown of its electronic parts and technical specifications. --- ## 1. Technical Overview This part is a **Single Port RJ11/RJ12 Modular Jack**. It is designed for Printed Circuit Board (PCB) mounting and is commonly used for telephone lines or low-speed data serial connections. ### Key Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ11 / RJ12 (6P4C or 6P6C) | | **Orientation** | Right Angle (Horizontal) | | **Mounting Type** | Through-Hole (THT) | | **Shielding** | Unshielded | | **Safety Standard** | UL Recognized (UL 94V-0) | | **Contact Plating** | Gold over Nickel | --- ## 2. Component Breakdown ### A. The Housing (Insulator) * **Material:** Usually high-temperature thermoplastic (e.g., PBT or Nylon). * **Flammability Rating:** The "UL" in the part number signifies compliance with **UL 94V-0**, meaning the plastic is self-extinguishing and meets strict fire safety standards. ### B. Contact Pins (Lead Frame) * **Configuration:** Typically "4R" or "6R" indicates the number of contacts. In this series, it usually refers to a 6-position housing. * **Material:** Phosphor Bronze is the standard base metal due to its excellent elasticity and conductivity. * **Plating:** The contact area is plated with **Gold** (often 3μ", 15μ", or 50μ") to prevent oxidation and ensure a low-resistance connection over thousands of mating cycles. ### C. Mechanical Design * **Right Angle (R):** The "R" in the suffix usually denotes a 90-degree orientation. This allows the cable to be plugged in parallel to the PCB, saving vertical space in slim devices. * **Solder Tails:** These are the pins that protrude through the PCB. They are tin-plated to ensure easy soldering during the manufacturing process. --- ## 3. Common Applications Due to its robust UL rating and standard footprint, this part is found in: 1. **Modems and Routers:** For DSL or telephone line inputs. 2. **Security Systems:** Connecting control panels to phone dialers. 3. **Industrial Controllers:** Used for RS-232 or RS-485 serial communication via modular cables. 4. **Telephony:** Standard wall jacks or internal PBX system connections. ---
