305-056-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-201 is a standard card edge connector receptacle featuring 56 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mounting with straight termination. The contacts are gold-plated copper alloy, rated for 5 A current, while the green thermoplastic polyester housing supports operation between -40 C and +105 C. Insulation resistance is 5 GOhms, and it accommodates a board thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for dual-edge card engagement
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator provides thermal stability
• Straight solder pin termination facilitates direct PCB integration

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Automotive electronic module interfaces
• Medical device circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal type and plating specifications against project requirements. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the straight mounting style aligns with the enclosure design constraints. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 56-position count suits applications needing moderate I/O density. Verify that the 5 A current rating meets the electrical load requirements. Consider the straight orientation for panel or direct board mounting scenarios where vertical headers are unsuitable.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles. The 305-056 variant specifically addresses mid-range connectivity needs within industrial and commercial electronics sectors, providing a standardized solution for modular board designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 56 positions and 3.96 mm pitch. Verify identical mechanical dimensions and electrical ratings before substitution. Alternative manufacturers may offer compatible connectors if pinout and form factor match exactly.
