The **JR16-R-DMMP1** is a high-performance circular connector part of the JR series, typically manufactured by **Hirose Electric**. These connectors are designed to meet Japanese Industrial Standards (JIS C 5432) and are widely used in industrial equipment due to their durability and reliable locking mechanisms. --- ### ## Technical Specifications & Components The part number breaks down into specific electronic and mechanical characteristics: | Attribute | Specification | Description | | :--- | :--- | :--- | | **Series** | JR | Standardized JIS-compliant circular connector. | | **Shell Size** | 16 | Indicates the outer diameter of the mating interface. | | **Shell Type** | R | Receptacle (the fixed part usually mounted on a panel). | | **Contact Gender** | DM | Male Contacts (Pins). | | **Termination** | MP | Multi-Purpose / Specific crimp or solder configuration. | | **Plating** | 1 | Typically refers to Silver or Gold plating (Model dependent). | --- ### ### Key Features of the JR16 Series * **Robust Shell:** Constructed from aluminum alloy or zinc alloy with a chrome or nickel plating to provide high mechanical strength. * **Threaded Coupling:** Uses a screw-on locking mechanism to ensure a secure connection that resists vibration and accidental disconnection. * **High Pin Density:** The "16" shell size allows for multiple pin configurations (though the specific "DMMP1" suffix usually dictates a standard 7 to 10 pin layout depending on the exact sub-variation). * **Electrical Reliability:** Designed for power and signal transmission in harsh environments. --- ### ### Typical Electrical Ratings While specific ratings can vary based on the number of pins used in the "16" shell size, standard JR16 connectors generally follow these parameters: 1. **Rated Current:** 5A to 10A per contact (depending on wire gauge). 2. **Rated Voltage:** AC 300V to 600V / DC 450V to 800V. 3. **Insulation Resistance:** Minimum 1,000 MΩ at 500V DC. 4. **Withstanding Voltage:** AC 1,000V to 2,000V for 1 minute. --- ### ### Common Applications The JR16-R-DMMP1 is frequently found in the following electronic systems: * **Factory Automation:** Connecting sensors, actuators, and motors. * **Communication Gear:** Robust interfacing for outdoor or mobile radio equipment. * **Medical Devices:** Reliable power delivery for diagnostic machinery. * **Measuring Instruments:** Secure signal integrity for high-precision testing tools.
