The **KAC-A6D-R** is a specific electronic component, typically categorized as a **D-Subminiature Connector** (specifically a Right-Angle, PCB-mount version). These are widely used in industrial, computing, and telecommunications hardware for reliable signal transmission. --- ## Technical Specifications The following table summarizes the key electronic and physical characteristics of the KAC-A6D-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Subminiature | | **Contact Gender** | Socket (Female) | | **Number of Pins** | 9, 15, or 25 (Varies by sub-series, usually 9) | | **Mounting Type** | Through-Hole, Right-Angle (90°) | | **Current Rating** | 3A - 5A per contact | | **Voltage Rating** | 250V AC/DC | | **Contact Material** | Copper Alloy (often Gold-plated) | | **Housing Material** | PBT Thermoplastic (UL 94V-0 rated) | --- ## Electronic Composition & Layout ### 1. The Contacts (Pins/Sockets) The KAC-A6D-R features precision-machined or stamped contacts. * **Conductivity:** Made from copper alloys to ensure low resistance. * **Plating:** Usually features gold flash or selective gold plating on the contact area to prevent oxidation and ensure a stable electronic connection over many mating cycles. ### 2. The Dielectric (Insulator) The electronic pins are separated by a high-grade plastic insulator. * **Dielectric Strength:** Designed to withstand high voltages without breaking down (typically tested up to 1000V AC for 1 minute). * **Insulation Resistance:** Usually rated at a minimum of 1000 MΩ. ### 3. EMI/RFI Shielding The "R" suffix often denotes a specific orientation or a metal shell design. * **Shell:** A steel or brass shell (often tin-plated) acts as a ground path and provides shielding against Electromagnetic Interference (EMI). * **Board Locks:** The component usually includes "harpoons" or board locks that provide a mechanical ground connection to the PCB's ground plane. --- ## Common Applications * **RS-232 Serial Communication:** Standard ports for older industrial machinery. * **VGA/Video Outputs:** Used in legacy display interfaces. * **PLC Interfaces:** Connecting Programmable Logic Controllers to external sensors or HMI panels. ---
