The **MA14FAD-R** is a specific type of high-performance **Micro-D connector** manufactured by ITT Cannon (as part of their MDM series or similar military-grade lines). These connectors are designed for applications where space is limited and high reliability is required. --- ### 1. Key Technical Specifications The "MA14FAD-R" part number typically breaks down into specific physical and electrical characteristics: | Feature | Specification Details | | :--- | :--- | | **Connector Type** | Micro-D (Rectangular) | | **Contact Density** | High density, typically 1.27mm (0.050") spacing | | **Number of Contacts** | Varies by sub-series, but often 9 to 51 pins | | **Current Rating** | 3 Amps maximum per contact | | **Dielectric Strength** | 600 VAC at sea level | | **Operating Temp** | -55°C to +125°C | --- ### 2. Component Composition This part is comprised of several critical sub-components designed for harsh environments: 1. **The Shell:** Usually made of aluminum alloy with electroless nickel or cadmium plating. The "R" in the suffix often denotes **RoHS compliance** (Environmental friendliness). 2. **Insulator:** High-grade diallyl phthalate or liquid crystal polymer (LCP) to prevent electrical arcing between pins. 3. **Contacts (Pins/Sockets):** Gold-plated copper alloy. The Micro-D system uses a "twist pin" design which provides 7 points of electrical contact for vibration resistance. 4. **Hardware:** The "FAD" designation often refers to the mounting hardware (e.g., Float Mounts or specific Jackscrew assemblies) used to secure the connector to a bulkhead or PCB. --- ### 3. Common Applications Due to its ruggedized nature, the MA14FAD-R is primarily used in: * **Aerospace:** Avionics systems and flight controls. * **Defense:** Missile guidance systems and tactical radios. * **Medical:** High-end imaging equipment and miniaturized implants. * **Oil & Gas:** Downhole drilling tools that experience extreme heat and vibration. --- ### 4. Part Number Breakdown Logic While specific to the manufacturer's catalog, the nomenclature usually follows this logic: ```text MA - 1 4 FAD - R | | | | | Series Type Size Hardware RoHS Status ``` ---
