306-024-520-178

Overview

The EDAC Inc. 306-024-520-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight installation style. It features 56 positions arranged in a dual female configuration with gold-plated copper alloy contacts. The connector utilizes a 3.96 mm (0.156 inch) pitch and is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with a thermoplastic polyester housing, it provides a low-profile insulator body suitable for space-constrained applications.

Feature Summary

• Dual edge female contact configuration for secure board insertion
• Gold plating on contact areas ensures reliable electrical conductivity
• Low profile insulator body design minimizes vertical space requirements
• Through-hole solder termination method for robust mechanical attachment

Applications

• Industrial control systems requiring high-density interconnects
• Communication equipment backplanes and daughter cards
• Consumer electronics internal module connections
• Medical device circuit board assemblies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact spacing, and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the straight through-hole mounting style aligns with the assembly orientation requirements. Cross-reference the 56-position dual-edge configuration with system design schematics to prevent interface mismatches during integration.

Selection Notes

Select this component when a high-contact-count solution with a wide 3.96 mm pitch is required for dual-sided card edge interfaces. The 56-position capacity supports complex signal routing compared to lower-count alternatives. The gold-plated copper alloy contacts offer superior corrosion resistance and durability for repeated mating cycles. Consider the low-profile housing dimensions if vertical clearance within the enclosure is limited.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors featuring a 3.96 mm contact spacing. The series is characterized by its versatility in accommodating various board thicknesses and providing reliable connectivity for industrial and commercial applications. The 306 series maintains consistent dimensional standards across different position counts, facilitating modular design approaches.

Replacement Considerations

Direct substitutes within the same series include parts with identical 3.96 mm pitch and 56-position dual-edge configurations, such as variations in housing color or flange options. Verify that any replacement maintains the same 1.57 mm board thickness tolerance and through-hole termination method to ensure mechanical fit.
