305-046-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-208 is a standard card edge connector from the 305 series, designed for reliable signal and power transmission. It features 46 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy with gold plating, ensuring durability and low contact resistance. Designed for panel mounting, it accommodates board thicknesses between 1.37 mm and 1.78 mm. The housing is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

• General-purpose data bus connections in electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, contact type, and material specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through current manufacturer datasheets as regulatory requirements may evolve. Cross-reference ordering guides to validate availability and lead times directly with authorized distributors.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Verify that the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the gold plating for applications requiring frequent insertion cycles or high reliability. Ensure the panel mount style aligns with the mechanical enclosure design constraints.
