305-074-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-074-556-512 is a standard card edge connector from the 305 series, designed for dual female termination on non-specified double-sided cards. It features 74 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The unit supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female termination configuration for reliable connection to double-sided edge cards
• Low profile insulator body design suitable for space-constrained panel installations
• Gold-plated copper alloy contacts ensure stable electrical performance and corrosion resistance
• Panel mount style with vertical orientation for secure board retention

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instruments needing high-density interconnects
• Automotive electronics applications demanding wide temperature tolerance

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and spacing parameters before procurement. Confirm that the target application utilizes double-sided edge cards compatible with the specified 0.062-inch thickness. Ensure that panel mounting provisions align with the vertical installation style and flange characteristics defined in the official datasheet documentation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 74 positions is required for double-sided PCBs. The 3.96 mm pitch accommodates standard board layouts while maintaining signal integrity through gold-plated contacts. Consider the -40°C to +105°C operating range for environments subject to thermal variation. Verify compatibility with existing panel cutouts due to the specific flange diameter and mounting style constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized solutions for card edge applications. The series offers various position counts and termination styles to support diverse electronic assembly needs. As a header type product, it facilitates secure mechanical and electrical connections between backplanes and plug-in modules in industrial and commercial hardware designs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series variants such as 305-070-556-568 or 305-074-556-578 if position counts or suffix variations differ. Ensure any substitute maintains identical 0.156-inch spacing and dual female termination characteristics to preserve mechanical fit and electrical functionality.
