305-020-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-207 is a standard card edge connector designed for dual-edge board insertion. It features 20 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum current rating of 5 A. The component utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. It is configured as a female receptacle with semi-bellows contact type, intended for panel or flush mount applications.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design with semi-bellows contact structure
• Gold plating on mating area with tin plating on tails over nickel underplating
• Flush mount flange feature with top opening and M3 threaded insert
• Thermoplastic polyester insulation providing high dielectric strength

Edgeboard Connectors Applications

• Panel-mounted electronic interface systems
• Industrial control module interconnections
• Telecommunications hardware backplanes
• Embedded system expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm the presence of the M3 threaded insert and flush mount flange configuration. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm that the tin-plated tail finish meets soldering process requirements for the target assembly line.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with a 3.96 mm pitch is required for panel mounting. The semi-bellows contact type offers reliable engagement for repeated insertions. Verify compatibility with the target board's edge guide slot dimensions and ensure the 5 A current rating aligns with the circuit load requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles. This specific part number denotes a 20-position dual-edge receptacle with specialized mounting features, distinguishing it from standard straight PCB mount variants within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 3.96 mm pitch, 20-position count, and dual-edge female configuration. Verify that any alternative part includes the M3 threaded insert and flush mount flange if panel installation is required. Contact termination style and current rating must be equivalent.
