305-022-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-558 is a dual-edge female card edge connector designed for panel mounting applications. It features 22 positions with a 3.96 mm (0.156 inch) pitch and accepts board thicknesses of 1.57 mm. The contacts are gold-plated copper alloy, providing a 5 A current rating and 5 GOhms insulation resistance. Operating temperatures range from -40°C to +105°C, with a thermoplastic housing.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-edge female contact configuration for reliable signal transmission
• Gold-plated copper alloy contacts ensure durability and conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control modules requiring polarized keying
• High-reliability circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing material variants, and packaging quantities. Ensure compatibility with required polarizing keys and verify that the panel mounting style matches the mechanical constraints of the target assembly before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount interface is required for double-sided edge cards. Confirm that the 3.96 mm pitch aligns with the PCB layout and that the 1.57 mm board thickness falls within the connector's acceptance range. Validate thermal requirements against the +105°C maximum operating limit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, utilizing a consistent 3.96 mm pitch architecture. The 305 series is engineered for robust performance in demanding environments, supporting both single and double-sided edge card configurations with standardized contact geometries.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series family for alternative position counts or mounting angles. Verify that any substitute maintains the same 3.96 mm pitch, 5 A current rating, and panel-mount orientation to ensure mechanical and electrical interchangeability without redesign.
