## Overview of the PRC05-R5M Connector The **PRC05-R5M** is a miniature multi-pin circular connector manufactured by **Hirose Electric** (or Tajimi Electronics, depending on the specific series lineage). It is primarily designed for high-density packaging in precision electronic equipment. ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Socket) | | **Gender** | Male Pins (Plug/Male Insert) | | **Number of Pins** | 5 Pins | | **Connection Type** | Push-Pull Locking Mechanism | | **Rated Voltage** | AC 100V / DC 140V | | **Rated Current** | 2A per contact | | **Withstanding Voltage** | AC 300V (for 1 minute) | | **Insulation Resistance** | 1,000 MΩ minimum (at DC 100V) | --- ### 2. Physical and Material Composition The PRC05 series is known for its durability and small footprint. The materials are selected for stability and electrical conductivity: * **Shell/Body:** Typically made of a zinc alloy or brass with nickel plating to provide EMI shielding and physical protection. * **Insulator:** High-grade synthetic resin (like PBT) with high dielectric strength. * **Contacts:** Copper alloy with **Gold plating** to ensure low contact resistance and prevent oxidation over time. * **Mounting:** This specific model is usually a panel-mount receptacle designed to be secured to a chassis. --- ### 3. Key Electronic Characteristics #### A. Push-Pull Locking Unlike threaded connectors, the PRC05-R5M uses a **push-pull** mechanism. This allows for quick mating and unmating while preventing accidental disconnection caused by pulling on the cable. #### B. Contact Resistance The contacts are designed to maintain a resistance of less than **10mΩ**. This is critical for signal integrity in measurement sensors and low-voltage data transmission. #### C. High-Density Design The "05" in the part number refers to the shell size. This is one of the smallest professional-grade circular connectors available, making it ideal for: * Handheld medical devices. * Industrial sensors. * Professional audio/video equipment. * Testing and measurement instrumentation. --- ### 4. Typical Wiring Pinout (Standard) While pin functions depend on the specific device, the physical arrangement is as follows: ```text (Top) [ 1 ] [5] [2] [4] [3] ``` *Note: Always verify the pinout against your specific device's service manual.*
