305-052-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-052-556-268 is a standard card edge connector from the 305 series, designed for dual female edgeboard applications. It features 52 positions with a 3.96 mm (0.156 inch) contact spacing and a row spacing of 3.56 mm (0.140 inch). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports a nominal PCB thickness of 1.57 mm (0.062 inch) and offers a current rating of 5 A. The unit employs solder pin termination and includes flanged mounting characteristics with threaded inserts.

Edgeboard Connectors Feature Summary

• Dual female configuration for secure edgeboard mating
• Gold-plated contacts ensure reliable signal transmission
• Flanged design with threaded inserts for panel stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm flange and thread specifications, as variations exist within the 305 series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with the target PCB thickness of 1.57 mm during mechanical design validation.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided female connection is required for 1.57 mm thick boards. The 3.96 mm pitch suits high-density layouts requiring robust mechanical retention. Consider the threaded flange feature if vibration resistance and precise panel alignment are critical design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options. The 305-052-556-268 specifically denotes a 52-position variant with dual female contacts and a flanged installation style, distinguishing it from non-flanged or single-row alternatives in the same family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series parts such as 305-050-556-502 for similar pitch but different position counts. Verify that substitute parts match the 1.57 mm board thickness requirement and dual female contact type to maintain mechanical and electrical interface integrity.
