305-056-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-501 is a dual-edge female card edge connector designed for vertical panel mounting. It features 56 positions with a 0.156-inch (3.96 mm) spacing across two rows. The contacts are made of copper alloy with gold plating and utilize a semi-crimping termination method for solder pin attachment. The housing is constructed from green thermoplastic polyester, supporting board thicknesses between 0.054 and 0.070 inches. Rated for -40°C to +105°C, it ensures reliable signal transmission in industrial environments.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration provides robust connection for non-specified double-sided edge cards
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Semi-crimping contact design secures the edge card firmly within the housing
• Thermoplastic polyester insulation offers stability across wide temperature ranges

Edgeboard Connectors Applications

• Industrial control systems requiring high-density I/O connections
• Communication equipment backplanes and interface modules
• Automotive electronics testing fixtures and diagnostic tools
• Medical device internal circuit board interconnections

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific flange and termination variations. Ensure compatibility with target PCB edge card thickness specifications before integration. Confirm RoHS compliance status if required by project regulations. Check lead times as distribution availability may vary. Validate that the selected variant matches the intended mechanical mounting constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is required for vertical panel installation. The 0.156-inch pitch accommodates standard edge card designs while providing ample spacing for signal integrity. Consider the gold plating thickness for applications involving frequent mating cycles. Evaluate thermal requirements against the specified operating range to ensure long-term reliability under load conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, a line of standard card edge connectors known for durability and precise manufacturing. The series offers various position counts and mounting styles to suit diverse electronic assembly needs. Components in this family typically feature standardized dimensions to facilitate easy replacement and system expansion in modular hardware designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants with different pin counts or slight dimensional changes. Cross-brand replacements require careful verification of pin pitch, housing height, and contact retention force. Ensure any alternative part maintains identical electrical ratings and mechanical fit for seamless integration.
