The **PS-HD34-R** is a specialized electronic component, specifically a **high-density D-Subminiature (D-Sub) Right-Angle Connector**. It is commonly used in industrial electronics, telecommunications, and computer hardware for high-pin-count signal transmission in a compact space. --- ### 1. Key Technical Specifications The "34" in the part number typically refers to the contact density (though in high-density variants, this often maps to a 3-row layout), and the "R" indicates a right-angle orientation for PCB mounting. | Specification | Details | | :--- | :--- | | **Connector Type** | High-Density D-Sub | | **Orientation** | Right-Angle (90-degree) | | **Mounting Type** | Through-Hole PCB Mount | | **Contact Gender** | Usually Receptacle (Female) or Plug (Male) | | **Number of Positions** | 44 (standard for HD 3-row) or 34 (proprietary) | | **Contact Plating** | Gold (for conductivity and corrosion resistance) | | **Shell Material** | Steel or Zinc plated with Tin/Nickel | --- ### 2. Core Electronic Parts & Materials A connector like the PS-HD34-R consists of several critical sub-components designed for electrical integrity: * **Insulator (Dielectric):** Usually made of **PBT (Polybutylene Terephthalate)** or high-temperature Thermoplastic. This prevents short circuits between the pins. * **Contacts (Pins/Sockets):** Made from **Copper Alloy** (Phosphor Bronze or Brass). These are the conductive paths for signals. * **Shell:** A metal frame (D-shape) that provides mechanical strength and EMI/RFI shielding. * **Boardlocks/Harpoons:** Mechanical clips that hold the connector to the PCB during the soldering process. --- ### 3. Usage & Applications Because of the **Right-Angle** design, this part is specifically used when a cable needs to plug into the edge of a board, keeping the profile low. * **Video Interfaces:** High-density D-subs are the basis for VGA connections. * **Industrial Control:** Connecting PLC (Programmable Logic Controllers) to sensors. * **Networking:** Serial data transmission where space on the back panel is limited. --- ### 4.
