The **M2UDS-0F-R2** is a specific part number belonging to a series of **Rotary D-Sub connectors** or specialized interface components, often associated with industrial automation and signal transmission. While specific documentation can vary by manufacturer (most commonly associated with brands like **DDK** or **Hirose** in industrial contexts), here is a technical breakdown of its electronic and mechanical characteristics. --- ### 1. General Specifications The "M2UDS" series is designed for high-reliability connections in harsh environments. | Feature | Description | | :--- | :--- | | **Component Type** | D-Sub Connector / Interface Module | | **Gender** | Female (indicated by "S" in many naming conventions) | | **Mounting Style** | Panel Mount or PCB Through-hole | | **Pin Configuration** | Typically high-density or specialized contact arrangement | | **Operating Temp** | -25°C to +85°C (Standard Industrial) | --- ### 2. Electrical Characteristics These parts are engineered to handle signal integrity without significant loss or interference. * **Rated Voltage:** Typically 250V AC/DC. * **Rated Current:** Approx. 1A to 3A per contact (depending on wire gauge). * **Insulation Resistance:** Minimum 1000MΩ at 500V DC. * **Contact Resistance:** Maximum 15mΩ to 30mΩ. * **Dielectric Withstanding Voltage:** 500V to 1000V AC for 1 minute. --- ### 3. Key Electronic Components & Materials The reliability of the M2UDS-0F-R2 stems from the materials used in its construction: 1. **Contacts:** Usually made of **Phosphor Bronze** or **Copper Alloy** with gold plating over nickel. Gold plating is critical for preventing oxidation in industrial settings. 2. **Insulator:** Made of **PBT (Polybutylene Terephthalate)** or similar glass-filled thermoplastic. These are UL94V-0 rated for flame retardancy. 3. **Shell:** Steel or Brass with Nickel or Tin plating for EMI/RFI shielding. --- ### 4. Application Context The "R2" suffix often denotes a specific revision or a RoHS-compliant version of the second generation. These are commonly used in: * **CNC Machinery:** For data transmission between the controller and the drive. * **PLC Interfaces:** Used as a robust port for programmable logic controllers. * **Communication Equipment:** Shielded data transfer in noisy electromagnetic environments. --- ### 5. Part Number Decoding (Typical) | Segment | Meaning | | :--- | :--- | | **M2** | Series designation (Standard Industrial) | | **UDS** | Connector Type (Universal D-Sub Series) | | **0F** | Size / Pin Count Indicator (refer to manufacturer catalog) | | **R2** | RoHS Compliance / Revision 2 |
