305-042-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-258 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features a 42-position configuration with a 3.96mm (0.156 inch) pitch across two rows. The connector utilizes female half-beam contacts made of copper alloy with gold plating for reliable signal transmission. It supports PCB thicknesses ranging from 1.37mm to 1.78mm and offers solder termination. The unit is rated for 5A current and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for double-sided card edge boards
• Gold-plated copper alloy half-beam contacts ensuring durable connection
• Panel mount installation style with vertical orientation
• Thermoplastic polyester insulation housing for structural stability

Edgeboard Connectors Applications

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct flange and termination variations. Confirm RoHS compliance status as required by project specifications. Cross-reference the manufacturer part number with distributor catalogs to validate availability and lead times prior to finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-edge interface is required with a 3.96mm pitch. Ensure the target PCB thickness falls within the 1.37mm to 1.78mm specification range. Consider the panel mount requirement and vertical orientation during mechanical design integration to align with chassis constraints.

Edgeboard Connectors Part Context
