305-052-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-201 is a standard card edge connector receptacle featuring 52 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic polyester housing provides insulation resistance of 5 GOhms. It supports board thicknesses of 1.57 mm and operates within a temperature range of -40 C to +105 C.

Edgeboard Connectors Procurement Notes

Verify the specific part number suffix against official EDAC documentation to confirm exact plating thickness and housing color specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before procurement. Confirm that the straight mounting style aligns with the mechanical assembly requirements of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Consider the 5 A current rating and -40 C to +105 C operating range for environmental suitability. Evaluate the straight PCB mount orientation against available panel space and mating connector alignment needs.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing a modular solution for board-to-board or board-to-backplane connections. The 305 series is characterized by its consistent 3.96 mm pitch and durable construction materials suitable for industrial applications.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-052-520-502 or 305-052-520-568 for alternative mounting or packaging options. Verify that substitute parts maintain the same 52-position count, dual-row layout, and 3.96 mm pitch to ensure mechanical and electrical compatibility.
