305-076-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-568 is a standard card edge connector from the 305 series, designed for dual-edge applications. It features 76 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it supports a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is made of UL 94V-0 thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

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

Edgeboard Connectors Applications

• Panel mount vertical interconnects
• Dual-edge card guide slot adapters
• High-density electronic system backplanes

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before integration. Confirm compliance with RoHS3 and REACH regulations as indicated in official documentation. Ensure that the thermal and electrical ratings align with the target application environment requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge configuration with 76 positions is required. The 3.96 mm pitch and 1.57 mm board thickness compatibility are critical constraints. Consider the 5 A current rating and 1800 VACrms insulation strength for high-power or high-voltage environments requiring robust connectivity.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent mechanical dimensions and electrical characteristics. The 305 series is characterized by its panel mount style and vertical orientation, providing a standardized solution for industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical pitch and board thickness specifications. Verify mechanical footprint and pinout compatibility before substituting with alternative part numbers from the same manufacturer family.
