305-054-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-502 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 54 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, ensuring an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct termination type and mounting variations. Confirm that the required PCB thickness aligns with the 0.062-inch nominal specification. Check RoHS compliance status if restricted substances are a project constraint. Ensure panel cutout dimensions match the flange specifications provided in the mechanical drawings prior to procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for vertical panel mounting. The 3.96 mm pitch offers a balance between signal density and mechanical stability. Consider the 5 A current rating for power distribution needs within the connector interface. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems.
