The **PRC07-R5M** is a high-reliability, miniature circular connector manufactured by **Tajimi Electronics Co., Ltd.** It is part of the PRC07 series, which is widely recognized for its "One-Touch" push-pull locking mechanism, commonly used in industrial and measurement equipment. --- ### 1. Technical Specifications The "PRC07-R5M" designation identifies specific characteristics of the component: | Feature | Specification | | :--- | :--- | | **Series** | PRC07 (Miniature Circular) | | **Connector Type** | Receptacle (R) | | **Number of Pins** | 5 Pins | | **Contact Gender** | Male (M) | | **Locking Mechanism** | Push-Pull Quick Release | | **Rated Voltage** | AC 300V (Peak) | | **Rated Current** | 2A | | **Withstanding Voltage** | AC 900V (for 1 minute) | | **Insulation Resistance** | 1,000 MΩ min. (at DC 500V) | --- ### 2. Key Component Features * **Push-Pull Coupling:** Unlike threaded connectors that require twisting, the PRC07-R5M allows for instant mating and unmating by simply pushing the plug into the receptacle. This is ideal for tight spaces where hand-turning is difficult. * **Compact Design:** The "07" series denotes a small shell size, making it suitable for handheld devices and compact electronic modules. * **Durability:** The shell is typically made of a zinc alloy or brass with chrome or nickel plating, providing high mechanical strength and EMI shielding. * **Solder Termination:** The internal pins are designed for solder-type connections, ensuring a permanent and low-resistance electrical path. --- ### 3. Pin Configuration (5-Pin Layout) The 5-pin configuration is often used for: 1. **Power + Data:** Carrying low-voltage DC power alongside differential signal pairs. 2. **Sensor Interfaces:** Connecting multi-axis sensors or transducers. 3. **Audio/Communication:** Used in high-end professional audio or radio communication headsets. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in sourcing or replacing the part: | Code | Meaning | | :--- | :--- | | **PRC** | Original Tajimi Series Name | | **07** | Shell Size / Series Number | | **R** | **Receptacle** (The fixed part mounted on the panel) | | **5** | Number of Contacts (5 Poles) | | **M** | **Male** Pin (The pins protrude from the insulator) | ---
