The **GSM06DTBN-S273** is a specific type of edge card connector manufactured by **Sullins Connector Solutions**. These components are primarily used to connect Printed Circuit Boards (PCBs) to a motherboard or backplane by gripping the "gold fingers" on the edge of the daughter card. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Sullins Connector Solutions | | **Number of Positions** | 12 Positions (6 per side) | | **Pitch (Spacing)** | 0.156" (3.96mm) | | **Number of Rows** | Dual Row | | **Mounting Type** | Through Hole, Right Angle | | **Termination** | Solder | | **Contact Finish** | Gold (typically 10µin) | | **Housing Material** | Thermoplastic (usually Polyester, PBT) | --- ### 2. Physical Design & Mounting The **S273** suffix in the part number usually refers to a specific modification or mounting style variant (often related to the mounting ear configuration or specific tail lengths). * **Right Angle Orientation:** Unlike vertical connectors, this part allows the daughter card to be plugged in parallel to the main board, which is ideal for low-profile enclosures. * **Mounting Ears:** This model typically features side mounting holes (ears) to secure the connector to the chassis or PCB with screws, providing mechanical strain relief. * **Dual-Readout:** It has contacts on both the top and bottom, allowing it to interface with double-sided PCB traces. --- ### 3. Materials and Durability * **Contact Material:** Phosphor Bronze is standard, providing a balance of conductivity and spring tension. * **Plating:** The gold plating on the contact mating area ensures low contact resistance and prevents oxidation over time, even in humid environments. * **Operating Temperature:** Generally rated for **-65°C to +125°C**, making it suitable for industrial applications. --- ### 4. Common Applications This connector is frequently found in: 1. **Industrial Controls:** Connecting PLC modules or sensor interface cards. 2. **Legacy Computing:** Interfacing with older bus architectures or custom expansion cards. 3. **Test Equipment:** Used in "bed-of-nails" testers or modular signal generators. 4. **Power Supplies:** Serving as a heavy-duty interface for power distribution cards.
