The **M2UDS-26-R** is a specific electronic component typically identified as a **Micro-Match** style ribbon cable connector or a high-density board-to-board/wire-to-board connector. It is widely used in industrial automation, telecommunications, and internal computer wiring. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications Table | Feature | Specification | | :--- | :--- | | **Connector Type** | IDC (Insulation Displacement Connector) | | **Number of Positions** | 26 Pins (2 Rows of 13) | | **Pitch (Spacing)** | 1.27mm (0.050") | | **Mounting Type** | Through-Hole / Cable Mount | | **Contact Material** | Phosphor Bronze (usually Tin-plated) | | **Voltage Rating** | 100V - 230V AC/DC | | **Current Rating** | 1.0A to 1.5A per contact | --- ### 2. Key Electronic Characteristics * **Insulation Displacement Technology (IDC):** This part is designed for "cold welding" to a ribbon cable. The connector teeth pierce the insulation of the wire to make contact with the conductor, eliminating the need for stripping or soldering individual wires. * **Low Contact Resistance:** Typically rated at **< 20 mΩ**, ensuring minimal signal loss across the 26 pins. * **Insulation Resistance:** Usually rated at **> 1000 MΩ**, providing high safety against short circuits between adjacent pins in high-density layouts. * **Dielectric Withstanding Voltage:** Can typically handle **500V AC** for one minute, making it robust for low-voltage data transmission. --- ### 3. Mechanical Design Features * **Dual-Row Configuration:** The "26" in the part number denotes the total pin count, arranged in two rows of 13 pins each. * **Polarization:** Most "R" suffix versions include a polarization bump or keying feature to prevent incorrect insertion (mating) into the header. * **Strain Relief:** Often used with an optional strain relief clip to prevent the ribbon cable from detaching under vibration or tension. * **Compact Footprint:** The 1.27mm pitch makes it significantly smaller than standard 2.54mm (0.1") headers, saving PCB real estate. --- ### 4. Common Applications 1. **Internal Data Links:** Connecting PCBs to LCD screens or sensor arrays. 2. **Industrial Controls:** Linking PLC modules to I/O interfaces. 3. **Medical Equipment:** Used in diagnostic devices where space-saving high-density wiring is required. 4. **Peripheral Interconnects:** Used inside printers, scanners, and networking hardware.
