305-076-520-512

Edgeboard Connectors Overview

The EDAC 305-076-520-512 is a standard card edge connector header featuring 76 positions in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for vertical panel mount installation, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it employs solder pin termination.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before procurement. Confirm that the receiving facility has the capability to handle panel mount headers. Ensure compatibility with polarizing key requirements if mechanical locking is necessary for the assembly. Check local distribution availability as stock levels may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 76 connections is required for vertical mounting applications. The 3.96 mm pitch accommodates standard .062 inch thick circuit boards. Consider the 5 A current rating and 1800 VACrms insulation limits to ensure electrical safety within the system design parameters.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its suitability for panel mount installations. The product line supports multiple position counts while maintaining consistent dimensional standards for board thickness and contact spacing.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-048-520-512 or 305-054-556-278 if different position counts are needed. Ensure any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness tolerance to guarantee physical fit.
