The part number **307-008-441-108** refers to a specific type of **Card Edge Connector** manufactured by **EDAC Inc.** These connectors are widely used in industrial equipment, legacy computing, and testing interfaces to connect printed circuit boards (PCBs) to a backplane or motherboard. --- ### Technical Specifications Below is a breakdown of the key physical and electrical characteristics for this specific part: | Characteristic | Specification | | :--- | :--- | | **Manufacturer** | EDAC Inc. | | **Series** | 307 / 357 Series | | **Number of Positions** | 8 Positions (Total) | | **Pitch (Spacing)** | 0.156" (3.96mm) | | **Number of Rows** | Single Row | | **Contact Termination** | Wire Hole (Solder Lug) | | **Mounting Type** | Chassis Mount (with Flange) | | **Contact Finish** | Gold Plating | | **Insulator Material** | Thermoplastic Polyester (PBT) | --- ### Part Number Breakdown Understanding the nomenclature helps in identifying variants within the same series: 1. **307**: Represents the series (Standard Card Edge Connector). 2. **008**: Indicates the number of contacts (8 contacts in a single row). 3. **441**: Refers to the contact termination style (in this case, **Wire Hole** or solder tail for manual wiring). 4. **108**: Indicates the mounting style (typically a **90-degree offset** or a specific flange/mounting ear configuration). --- ### Key Features and Applications #### Features * **Durability:** Designed for high-reliability connections with a bifurcated contact design (split contacts) to ensure a stable electrical path even under vibration. * **Versatility:** The 0.156" pitch is a standard for power distribution and older computer bus architectures. * **Gold Contacts:** Provides excellent conductivity and prevents oxidation over long periods. #### Common Applications * **Industrial Controls:** Used in PLC systems and rack-mounted industrial hardware. * **Arcade & Gaming:** Often found in vintage arcade cabinets for connecting game boards. * **Power Supplies:** Used as a heavy-duty interface for modular power components. * **Test Equipment:** Ideal for creating custom break-out boards or interface jigs. --- ### Installation Note Because this part features **Wire Hole (Solder Lug)** terminations, it is intended for point-to-point wiring rather than being soldered directly onto another PCB. You would typically strip a wire, insert it into the hole at the base of the pin, and apply solder to create a permanent connection.
