Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of this component series: | Feature | Specification | | :--- | :--- | | **Connector Type** | D-Sub (DB15) | | **Number of Positions** | 15 Pins | | **Gender** | Female (Socket) / Male (Plug) - Varies by suffix | | **Mounting Type** | Through-Hole / PCB Mount | | **Current Rating** | ~3A to 5A (Standard) | | **Voltage Rating** | 250V AC/DC | | **Contact Material** | Copper Alloy (often Gold-plated) | | **Insulator Material** | PBT (Polybutylene Terephthalate) UL94V-0 | --- ### 2. Key Electronic Features #### A. Contact Plating and Conductivity * **Signal Integrity:** The internal pins/sockets are generally plated with gold over nickel. This prevents oxidation and ensures low contact resistance, which is critical for low-voltage data signals. * **Durability:** The "R/Q" designation often refers to specific compliance or packaging standards (like RoHS compliance), ensuring the part meets modern environmental safety regulations. #### B. Shielding and EMI Protection * **Metal Shell:** The outer casing is typically made of tin-plated steel. This acts as a **Faraday cage**, protecting the internal signals from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). * **Grounding:** The shell provides a path to the chassis ground when mounted, which is essential for preventing noise in sensitive electronic circuits. #### C. Mechanical Stability * **Solder Tails:** The pins are designed for wave soldering or manual soldering onto a PCB. * **Board Locks:** Many versions include "harpoon" style board locks or threaded inserts (4-40 UNC) to ensure the connector remains mechanically fastened to the board and the mating cable remains secure. --- ### 3. Typical Applications 1. **Industrial Automation:** Used for PLC (Programmable Logic Controller) communication and sensor arrays. 2. **Legacy Video/Data:** Often found in VGA-style interfaces or serial data communication (RS-232/RS-422). 3. **Medical Equipment:** Reliable signal routing for diagnostic machinery. 4. **Telecommunications:** Network hardware and rack-mounted equipment.
