305-058-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-058-556-208 is a standard card edge connector designed for vertical panel mounting applications. It features a dual-edge configuration with 58 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The housing is made of thermoplastic material, providing durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact mechanical dimensions and termination styles. Ensure compatibility with required polarizing keys if alignment features are necessary for the assembly. Confirm RoHS compliance status through the latest datasheet documentation before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution with 58 positions is required. The 3.96 mm pitch suits applications needing moderate density without excessive footprint constraints. Verify that the target PCB thickness falls within the acceptable range of 1.37 mm to 1.78 mm for proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and termination options to accommodate diverse design requirements. Components in this family typically feature thermoplastic insulators and gold-plated contacts for reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 Series variants such as 305-050-556-208 or 305-054-556-278 for similar form factors. Ensure that any substitute maintains the same 3.96 mm pitch and dual-edge configuration to preserve mechanical fit and electrical continuity within the existing system architecture.
