305-054-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-258 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 54 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, supporting board thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides 1800VACrms dielectric voltage strength
• Features semi-waffle pack contact design for reliable engagement

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing dual-edge card interfaces
• Test and measurement devices needing high-dielectric strength connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact flange characteristics and mounting hardware configurations. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before final procurement approval.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 54-position interface with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and 1800VACrms insulation capability for applications demanding high electrical isolation. Verify that the chosen polarizing key configuration matches the mechanical constraints of the mating card assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability applications. The series offers various position counts and flange options to accommodate diverse panel thicknesses and mounting requirements. These connectors are widely used in sectors requiring durable, solder-pin terminated interfaces for double-sided edge cards.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-054-521-202 or 305-054-521-278 if different flange styles or packaging formats are needed. Ensure any substitute maintains the same 3.96 mm pitch and 54-position count to preserve mechanical fit.
