305-076-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-268 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 76 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. The unit utilizes a solder pin termination type for secure mounting.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density interconnect applications
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount installation style with vertical orientation
• Compatible with standard 0.062-inch thick PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation with modular board architectures

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required row spacing and mounting hardware configuration. Confirm compatibility with the target PCB thickness of 1.57 mm before integration. Ensure the gold plating specification meets the environmental requirements for the intended operational lifespan and cycle count.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for panel-mounting. The 76-position count supports substantial I/O density. Verify that the vertical mounting angle aligns with the chassis design constraints and that the solder pin termination method is compatible with the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-076 variant specifically provides a high-pin-count solution for dual-edge boards, maintaining consistent electrical characteristics across the family while differing in mechanical form factors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the 76-position count and 3.96 mm pitch. Verify that alternative substitutes maintain identical row spacing and PCB thickness acceptance criteria to ensure mechanical fit without modification.
