305-056-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-512 is a dual-edge female card edge connector featuring 56 positions with a 0.156-inch (3.96mm) spacing. Designed for through-hole mounting, it utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. The component supports board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card applications
• Gold-plated semi-waffle contact design for reliable signal transmission
• Thermoplastic polyester insulation providing structural stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to ensure correct flange and termination specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and production batch.

Edgeboard Connectors Selection Notes

Select this model when a high-density 56-position interface is required with standard 3.96mm pitch. Ensure the mating card thickness falls within the 1.37mm to 1.78mm range. Consider thermal ratings and mechanical locking requirements relative to the application environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. It shares common design characteristics with other models in the series, such as consistent spacing and material composition, while differing primarily in position count and specific mounting features.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 0.156-inch pitch and 56-position count. Verify identical flange dimensions and termination styles before substitution to maintain mechanical fit and electrical continuity.
