The **CM09-R25P** is a specific model of a circular connector, typically associated with the **DDK (Dai-ichi Denshi Kogyo)** CM09 series. These connectors are designed for industrial applications requiring robust, waterproof, and high-reliability connections. --- ## 1. Component Overview The CM09-R25P is a **Right-Angle Plug** connector. It is part of a miniature circular series often used in factory automation, robotics, and sensor equipment. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | CM09 (Miniature Waterproof Circular) | | **Shell Type** | Right-Angle Plug (90-degree) | | **Number of Contacts** | 25 Pins | | **Termination Method** | Solder type (Standard) | | **Waterproof Rating** | IP67 (when mated) | | **Current Rating** | ~1A to 3A (depending on wire gauge) | | **Locking Mechanism** | Push-on / Screw-on hybrid (One-touch) | --- ## 2. Key Electronic Features ### High-Density Layout The "25P" indicates a **25-pin configuration**. For its compact size, this represents a high-density layout, allowing for complex signal transmission or low-power distribution in a small footprint. ### Shielding and EMI Protection The shell is typically made of a zinc alloy or similar plated metal. This provides: * **EMI Shielding:** Protects sensitive signals from electromagnetic interference. * **Grounding:** The metal housing allows for continuous grounding from the cable to the chassis. ### Environmental Sealing It features internal O-rings and gaskets. This ensures that even in environments with moisture or dust, the electrical contact points remain clean and conductive. --- ## 3. Physical Construction The "R" in the part number signifies the **Right-Angle** orientation. This is crucial for electronic assembly in tight spaces where a straight cable exit would be impossible or put too much strain on the wire. ### Materials * **Contacts:** Gold-plated copper alloy (to prevent oxidation and ensure low contact resistance). * **Insulator:** Synthetic resin (high dielectric strength). * **Shell:** Zinc alloy with nickel or chrome plating. --- ## 4. Typical Applications 1. **Industrial Robotics:** Connecting sensors on robotic arms where space is constrained. 2. **Medical Equipment:** High-reliability signal transmission for diagnostic tools. 3. **Encoders:** Interfacing between motors and control units.
