305-042-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) thickness and offers a current rating of 5 A. It employs a half-bevel contact type for secure mating and is housed in green thermoplastic polyester. The unit is rated for operation between -40°C and +105°C, provides 5 GOhms insulation resistance, and complies with RoHS3 standards.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal style and plating specifications against project requirements. Confirm that the selected variant matches the required PCB thickness range and mounting orientation. Ensure compliance with environmental regulations such as RoHS3 if applicable to the final assembly. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components. Validate supply chain authenticity through authorized channels only.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and operating temperature range for suitability in industrial environments. Evaluate the half-bevel contact design for compatibility with target PCB edge profiles. Compare alternative series within the EDAC portfolio if different mounting styles or contact counts are needed.
