305-034-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-034-556-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-edge female configuration with 34 positions and a contact pitch of 3.96 mm (0.156 inches). The contacts are constructed from copper alloy with gold plating and utilize a semi-bellows termination type for solder pin end connections. The housing is made of green thermoplastic material, supporting board thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration ensures reliable mating with specified card edge boards.
• Semi-bellows contact design provides enhanced mechanical retention and electrical stability during insertion.
• Gold-plated copper alloy terminals offer corrosion resistance and low contact impedance.
• Thermoplastic insulator housing supports high-temperature operation up to 105°C.

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module signal routing
• Telecommunications equipment backplane interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact termination style and mounting hardware configuration. Confirm that the board thickness specification aligns with the target PCB design constraints. Ensure compliance with RoHS directives if environmental regulations apply to the assembly process. Cross-reference the manufacturer datasheet for precise dimensional tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount interface with a 3.96 mm pitch is required. The dual-edge design suits applications needing full-width connectivity across the board edge. Consider the semi-bellows contact type for environments requiring robust mechanical locking. Verify thermal ratings against operational extremes to ensure long-term reliability in industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options tailored for diverse industrial and commercial electronics. The 305-034 variant specifically addresses needs for moderate density interconnects with durable gold-plated contacts and thermoplastic insulation suitable for panel integration.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 3.96 mm pitch, 34-position count, and dual-edge female configuration. Verify that alternative components maintain identical semi-bellows contact geometry and panel-mount vertical orientation. Ensure thermal and current ratings meet or exceed the original specifications for safe operation.
