Overview
The EDAC Inc. model 306-024-520-168 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 56 positions arranged in two rows. The contact spacing is 3.96 mm (0.156 inches), and it accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are gold-plated copper alloy, rated for 5 A current at an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.
Feature Summary
- Dual row female contact configuration for high-density board connections
- Gold-plated copper alloy contacts ensure reliable signal transmission
- Low profile thermoplastic insulator body suitable for space-constrained panels
- Vertical panel mount style provides secure mechanical installation
Applications
- Industrial control system interconnects
- Telecommunications equipment backplanes
- Medical device circuit board interfaces
- Consumer electronics module connections
Procurement Notes
Verify the specific ordering suffix against the official EDAC datasheet to confirm pin count, plating, and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-row 56-position layout matches the design requirements. Check RoHS compliance status if required by project specifications. Validate panel mounting hole dimensions prior to procurement.
Selection Notes
Select this component when a dual-row card edge interface is required for vertical panel mounting. The 3.96 mm pitch supports standard board widths while maintaining compact form factors. Gold plating is essential for environments requiring corrosion resistance and low contact resistance. Verify that the 5 A current rating meets the electrical load requirements of the application circuitry.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse electronic assembly needs. EDAC manufactures these components using thermoplastic materials for durability and consistent electrical performance across industrial temperature ranges.
Replacement Considerations
Direct substitutes must match the 56-position dual-row format and 3.96 mm pitch. Verify identical panel mount orientation and PCB thickness tolerance. Cross-reference contact material and plating specifications to maintain electrical continuity.
