Based on the technical nomenclature, the **10280-R21TS** typically refers to a high-density, professional-grade **MDR (Mini Delta Ribbon)** connector, often manufactured by companies like **3M**. These components are widely used in industrial telecommunications, medical imaging, and high-speed data transmission systems. --- ## Technical Specifications The following table outlines the general electronic and physical characteristics of the 10280 series: | Parameter | Specification | | :--- | :--- | | **Connector Type** | MDR (Mini Delta Ribbon) Receptacle | | **Pin Count** | 80 Positions (High Density) | | **Pitch** | 0.050" (1.27 mm) | | **Mounting Style** | Right Angle Through-Hole (T/H) | | **Shielding** | Fully Shielded (EMI/RFI protection) | | **Current Rating** | 1.0 Ampere per contact | | **Voltage Rating** | 150 V AC/DC | --- ## Component Breakdown ### 1. The Connector Interface (MDR) The "102" prefix indicates the **Mini Delta Ribbon** family. Unlike standard pin-header connectors, MDR uses a ribbon-style contact. * **Durability:** Designed for high-cycle mating (typically 500+ cycles). * **Wiping Action:** The contacts are designed to "wipe" against each other during insertion, removing surface oxidation and ensuring a clean signal. ### 2. Physical Layout (80-R21TS) * **80:** Denotes the number of active pins/conductors. * **R21:** Typically refers to the specific mounting configuration. In this case, it is a **Right-Angle** PCB mount, meaning the cable enters parallel to the board. * **TS:** Often indicates the plating or specific tail length (e.g., **T**in-Lead or **S**elective Gold plating). ### 3. Electronic Protection (EMI/ESD) The outer metal shell serves two primary functions: * **Mechanical Grounding:** Provides a sturdy connection to the chassis. * **Signal Integrity:** The shroud acts as a Faraday cage to prevent electromagnetic interference (EMI) from leaking into or out of the high-speed data lines. --- ## Common Applications Because of its high density and reliable signal integrity, the 10280-R21TS is found in: * **Camera Link Systems:** Used in industrial machine vision. * **LVDS Signaling:** Low-Voltage Differential Signaling for displays. * **Test & Measurement:** Oscilloscopes and logic analyzers requiring multi-channel inputs. * **SCSI Interfaces:** Older high-speed storage communication.
