The **MA14FCX-R** is a specialized high-density, high-performance connector part, typically associated with the **MDR (Mini Delta Ribbon)** family produced by 3M or similar manufacturers. These connectors are designed for high-speed data transmission and space-saving applications. --- ### 1. Technical Specifications The "MA14FCX-R" designation usually refers to a specific configuration of a ribbon cable connector. Below are the general technical characteristics: | Parameter | Description | | :--- | :--- | | **Connector Type** | MDR (Mini Delta Ribbon) / SCSI style | | **Pin Count** | 14 Positions (Pins) | | **Mounting Type** | Cable Mount (IDC - Insulation Displacement Contact) | | **Gender** | Female (Receptacle/Socket) | | **Contact Plating** | Gold over Nickel | | **Pitch** | 1.27 mm (0.050") | | **Shielding** | Fully Shielded for EMI/RFI protection | --- ### 2. Key Features * **High-Density Design:** The 1.27mm pitch allows for a high number of signal paths in a very small footprint compared to standard D-sub connectors. * **EMI Protection:** The "X" and "R" suffixes often denote specific shielding properties or RoHS compliance (Lead-free), ensuring minimal electromagnetic interference in sensitive electronics. * **IDC Termination:** The part uses Insulation Displacement Contacts, allowing it to be "crimped" onto a flat ribbon cable without the need for stripping individual wires or soldering. * **Ribbon Locking:** Typically features a latching mechanism (either wire clips or plastic tabs) to prevent accidental disconnection in high-vibration environments. --- ### 3. Common Applications This part is frequently used in industrial and telecommunications equipment, including: 1. **Industrial Automation:** Connecting PLCs to sensors or motor drives. 2. **Medical Equipment:** Internal data routing for imaging and diagnostic tools. 3. **Test & Measurement:** High-speed data acquisition systems. 4. **Legacy Computing:** Small Computer System Interface (SCSI) peripheral connections. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code generally breaks down as follows: | Code | Meaning | | :--- | :--- | | **MA** | Series prefix (Miniature/MDR) | | **14** | Number of contacts (14 pins) | | **FC** | Female Connector / Flat Cable orientation | | **X-R** | Revision code or RoHS compliant indicator | ---
