305-022-520-578

Edgeboard Connectors Overview

The EDAC 305-022-520-578 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual-row configuration with 22 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Utilizes gold-plated copper alloy contacts for reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing standardized PCB modules
• Test and measurement equipment with modular card architectures

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct housing color, termination style, and flange options. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Cross-reference the board thickness tolerance with the specified 1.57 mm nominal requirement to guarantee proper mechanical fit and electrical contact integrity during installation.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for dual-edge cards. Ensure the design accommodates the 3.96 mm pitch and allows space for polarizing keys if used. Verify that the thermal environment remains within the -40°C to +105°C operational limits. Consider the 5 A current rating relative to the total pin count and duty cycle requirements for the specific application load.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series offers various position counts and mounting styles, maintaining consistent electrical performance across models.
