305-056-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-056-521-202 is a standard card edge connector receptacle featuring 56 positions with dual contact readout. It utilizes a 0.156-inch (3.96 mm) pitch and a 0.140-inch (3.56 mm) row spacing. Designed for .062-inch (1.57 mm) nominal thickness printed circuit boards, it employs gold-plated copper alloy contacts housed in a green thermoplastic polyester body. The component supports panel mount and through-hole installation via solder termination.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the complete part number including the suffix to confirm specific housing color and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status if required by project regulations. Cross-reference the official datasheet for precise dimensional tolerances and mating force requirements to guarantee mechanical fit within the assembly constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for 56-position interfaces. The 0.156-inch pitch suits applications needing moderate density without excessive miniaturization. Gold plating is preferred for environments demanding corrosion resistance and stable signal transmission. Verify that the mounting style aligns with the available panel or board space constraints.
