The **MJS6-R** refers to a specific type of **Modular Jack (RJ11/RJ12)** connector, typically manufactured by companies like **METZ CONNECT** or similar electronic component suppliers. It is primarily used for telecommunications and data transmission. ### 1. Key Technical Specifications The "MJS" series generally denotes a modular jack with specific mounting characteristics. Below are the common specifications for the MJS6-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | RJ11 / RJ12 (6 Positions) | | **Contacts Loaded** | Usually 6 (6P6C) | | **Mounting Type** | Through-Hole (PCB Mount) | | **Orientation** | Right Angle (Side Entry) | | **Shielding** | Unshielded (Standard) | | **Contact Material** | Phosphor Bronze with Gold Plating | --- ### 2. Physical Construction The MJS6-R is built with three main components designed for durability and signal integrity: * **Insulator Body:** Made of high-temperature thermoplastic (often UL 94V-0 rated), which allows the part to withstand wave soldering processes. * **Contact Pins:** The pins are bent at a **90-degree angle** to allow the jack to be mounted on the edge of a Printed Circuit Board (PCB). * **Gold Plating:** The contact area is plated with gold (measured in micro-inches) to prevent oxidation and ensure a low-resistance connection over thousands of mating cycles. --- ### 3. Electrical Characteristics To ensure safe operation in communication equipment, these parts follow strict electrical limits: ```yaml Electrical_Properties: Voltage_Rating: 125 VAC RMS Current_Rating: 1.5 Amperes Contact_Resistance: 20mΩ Max (initial) Insulation_Resistance: 500MΩ Min @ 500V DC Dielectric_Strength: 1000V AC RMS 60Hz, 1 min ``` --- ### 4. Common Applications The MJS6-R is a legacy but still widely used component in various electronic devices: 1. **Telephony:** Landline telephones, modems, and fax machines. 2. **Security Systems:** Control panels that dial out to monitoring centers. 3. **Industrial Controls:** Used for RS232 or RS485 serial communication over modular cables. 4. **Networking:** Low-speed data transfer interfaces.
