305-042-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-268 is a standard card edge connector from the 305 series, designed for dual female connections with 42 positions. It features a 0.156-inch (3.96 mm) pitch and supports board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB panel mounting requirements and verify that the 42-position layout matches the design footprint. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, high-density connection is required for thick circuit boards. The 3.96 mm pitch accommodates larger signal traces compared to finer pitches. Verify that the panel mount style aligns with the enclosure design constraints. Consider the 5 A current rating for power distribution needs within the specified thermal operating range.
