305-060-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-060-556-278 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features a 60-position configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a continuous current rating of 5 A and a dielectric strength of 1800 VACrms. The contacts are gold-plated copper alloy, while the insulator body is green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body design
• Utilizes half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• High-density electronic assemblies

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required mounting style and termination type. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the selected variant supports the necessary voltage ratings for the intended circuit environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for non-specified dual-edge cards. The 3.96 mm pitch suits applications needing high pin counts within limited panel space. Consider the 5 A current rating for power distribution needs. Verify that the vertical panel mount style aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its standardized 3.96 mm pitch and durable construction suitable for repeated mating cycles. Similar models in the series vary primarily by position count and specific mounting configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with matching 60 positions and 3.96 mm pitch. Cross-brand replacements require verification of identical mechanical dimensions, contact spacing, and electrical ratings to maintain system integrity.
