305-052-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-503 is a standard card edge connector designed for reliable signal transmission in electronic assemblies. This component features a dual female configuration with 52 positions arranged in two rows. It utilizes a 0.156-inch (3.96 mm) pitch to accommodate specific board layouts. The connector supports a maximum board thickness of 1.57 mm and employs gold-plated copper alloy contacts to ensure low resistance and durability. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, providing necessary insulation and mechanical stability.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific contact plating and housing variations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the receiving system supports the required 52-position dual-row layout. Check for any specific environmental certifications if operating in harsh conditions. Validate that polarizing key requirements are met by the mating assembly design.

Edgeboard Connectors Selection Notes

Select this connector when a 52-position dual-row interface is required with a 0.156-inch pitch. Consider the 5 A current rating and 1800VACrms dielectric strength for circuit safety. Evaluate the vertical panel mount style against available space constraints. Ensure the application environment falls within the specified -40°C to +105°C operational range. Verify that the thermoplastic housing material meets chemical resistance 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 to support diverse electronic design requirements. The 305 series is known for its robust construction and compatibility with industry-standard polarizing keys. It serves as a critical interconnect solution in applications requiring secure and repeatable board-to-board or board-to-panel connections.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series for alternative position counts. Verify that substitute connectors maintain the same 0.156-inch pitch and dual-row configuration. Ensure replacement options support the same 1.57 mm board thickness constraint. Confirm that electrical ratings meet or exceed the original 5 A and 1800VACrms specifications.
