The **10220-R20CS** refers to a specific type of high-density interconnect component, primarily manufactured by **3M**. It is part of the **Mini Delta Ribbon (MDR)** series, which is widely used in industrial automation, machine vision, and telecommunications. --- ## 1. Core Specifications The part is a **Shrouded Boardmount Receptacle**. Below are the key technical specifications: | Feature | Specification | | :--- | :--- | | **Connector Type** | Receptacle (Female) | | **Number of Positions** | 20 Pins | | **Pitch** | 0.050" (1.27 mm) | | **Mounting Type** | Through Hole, Right Angle | | **Termination** | Solder | | **Shielding** | Shielded (Metal Shroud) | | **Contact Plating** | Gold over Nickel | --- ## 2. Key Electronic Features ### A. High-Density Design With a pitch of **1.27 mm**, this connector allows for a high number of signal paths in a compact footprint. This is essential for modern PCB designs where space is limited. ### B. EMI/ESD Protection The "Shrouded" design includes a metal shell that provides: - **Grounding:** Ensures a stable ground path between the cable and the PCB. - **EMI Shielding:** Protects sensitive high-speed signals from electromagnetic interference. ### C. Wiper-on-Wiper Contact The internal contact mechanism uses a "wiper" system rather than a standard pin-and-socket. This provides: - Increased reliability through multiple points of contact. - High durability for repeated mating cycles. - Lower insertion force compared to traditional D-Sub connectors. --- ## 3. Typical Applications The 10220-R20CS is commonly found in environments requiring robust data transmission: 1. **Camera Link Interface:** Frequently used in high-speed industrial cameras and frame grabbers. 2. **Servo Drives:** Used for feedback signals and control interfaces in CNC machines. 3. **Medical Instrumentation:** Employed in diagnostic equipment where signal integrity is critical. 4. **Data Communications:** High-speed I/O for networking hardware. --- ## 4. Part Number Breakdown Understanding the 3M nomenclature for this series: * **102:** Series designation (MDR Receptacle). * **20:** Number of pins/contacts (20-way). * **-R20:** Right angle mounting orientation. * **CS:** Specific plating/packaging or mounting flange variation (typically denotes a standard solder tail with specific screw-lock hardware). ---
