The **10240-R21TS** refers to a specific part number typically associated with high-density interconnect solutions, specifically the **3M™ Mini Delta Ribbon (MDR) Series** connectors. These are widely used in industrial automation, machine vision, and telecommunications. --- ### 1. General Specifications The 10240-R21TS is a **40-position, right-angle, shielded boardmount plug**. Below are the core technical details: | Feature | Specification | | :--- | :--- | | **Series** | Mini Delta Ribbon (MDR) | | **Number of Contacts** | 40 | | **Orientation** | Right Angle (Horizontal) | | **Mounting Type** | Through Hole (Solder) | | **Shielding** | Fully Shielded (Metal Shroud) | | **Pitch** | 0.050" (1.27 mm) | | **Contact Plating** | Gold over Nickel | --- ### 2. Key Features & Design * **Wiper-on-Wiper Contact:** The design uses a ribbon-style contact system rather than traditional pins. This provides a more reliable connection under vibration and allows for high-cycle durability. * **EMI/ESD Protection:** The metal shroud and shielded interface are designed to minimize electromagnetic interference (EMI), making it suitable for high-speed data transmission. * **Mechanical Stability:** It often includes board locks or "ground lock" features (indicated by certain suffixes) to ensure the connector remains securely attached to the PCB during the mating/unmating process. * **Screw or Latch Interface:** This specific series usually supports various locking mechanisms to prevent accidental disconnection. --- ### 3. Common Applications Due to its high density and robust shielding, the 10240-R21TS is commonly found in: 1. **Camera Link Systems:** Used in industrial cameras and frame grabbers for machine vision. 2. **LVDS Interfacing:** High-speed low-voltage differential signaling for displays. 3. **Medical Equipment:** Reliable data transfer for imaging and diagnostics. 4. **Test and Measurement:** High-pin count interfaces for laboratory instruments. --- ### 4. Technical Drawing & Footprint * **Pitch:** The 1.27mm (0.050 inch) spacing is half the distance of standard 2.54mm headers, allowing for 40 pins in a relatively small footprint. * **Material:** The insulator is typically a high-temperature glass-filled thermoplastic (LCP or PBT) to withstand wave soldering.
