305-056-555-212

Edgeboard Connectors Overview

The EDAC Inc. model 305-056-555-212 is a standard card edge connector header featuring 56 positions arranged 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 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The insulator body is made of thermoplastic polyester, presented in green color.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided PCBs

• Gold-plated copper alloy contacts provide corrosion resistance
• Thermoplastic polyester housing ensures thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact termination style and insulation color variations. Ensure compatibility with target PCB thickness tolerances before finalizing procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and regional shipping restrictions.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for thick PCB applications. The 3.96 mm pitch offers robust mechanical engagement compared to finer pitches. Confirm that the vertical panel mount style aligns with the enclosure design constraints. Evaluate the gold plating requirements against environmental exposure conditions to determine if this specification meets long-term reliability needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series provides various position counts and termination options to support diverse electronic assembly requirements. The 305-056 variant specifically addresses applications needing substantial I/O density within a compact footprint.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with matching 56-position dual-row configurations. Verify identical 3.96 mm spacing and 1.57 mm board thickness acceptance criteria. Ensure equivalent gold plating specifications and thermoplastic insulation materials are maintained for interchangeability.
