The **JR16-R-4MFP1** is a specific electronic component from the **JR Series** of circular connectors, manufactured by **Hirose Electric**. These connectors are known for their high reliability, robust metal shells, and widespread use in industrial machinery and communication equipment. --- ### 1. Technical Specifications The part number follows a specific nomenclature. Below is a breakdown of its physical and electrical characteristics: | Feature | Specification | | :--- | :--- | | **Connector Type** | Circular Connector (Plug/Receptacle) | | **Series** | JR Series (High-performance standard) | | **Shell Size** | 16 | | **Number of Contacts** | 4 | | **Contact Gender** | Male/Female (Dependent on configuration; 'P' usually denotes Pin) | | **Mounting Type** | Flange Mount / Panel Mount | | **Body Material** | Aluminum Alloy (Nickel or Chrome plated) | | **Current Rating** | Typically 10A - 30A (depending on wire gauge) | | **Voltage Rating** | AC 300V - 600V (depending on environment) | --- ### 2. Key Components and Design The JR16-R-4MFP1 is engineered for industrial environments where durability is critical. * **Outer Shell:** A rugged metal shell that provides excellent EMI (Electromagnetic Interference) shielding and physical protection against impacts. * **Insulator:** High-grade synthetic resin that maintains high insulation resistance even under high-voltage loads. * **Locking Mechanism:** Uses a threaded coupling system to ensure a secure, vibration-proof connection. * **Solder/Crimp Terminals:** Designed for permanent wiring, allowing for stable electrical conductivity over time. --- ### 3. Pinout and Internal Wiring While specific pinout diagrams depend on the user's application, the **4-pin configuration** is commonly used for: 1. **DC Power Supply:** (V+, GND, and two signal lines). 2. **Single-Phase AC:** (Live, Neutral, Ground, and an auxiliary/shield). 3. **Motor Control:** Providing power to small industrial motors or actuators. --- ### 4. Common Applications * **Industrial Automation:** Used in PLC (Programmable Logic Controller) interfaces. * **Medical Equipment:** High-reliability power and data transmission. * **Measurement Devices:** Used for testing equipment that requires frequent plugging and unplugging. * **Communication:** Robust signal transmission in harsh radio environments. --- ### 5. Maintenance and Handling To ensure the longevity of the connector: * **Mating Cycles:** Hirose JR series are rated for hundreds of mating cycles, but contacts should be kept free of dust and oxidation. * **Sealing:** If used in outdoor environments, ensure the appropriate gaskets are used to maintain environmental ratings.
