305-022-520-508

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-508 is a standard card edge connector from the 305 series, designed for panel mount installation with vertical orientation. It features a dual row configuration providing 22 positions with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. The termination method is solder pin, suitable for through-hole mounting on printed circuit boards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction
• Designed for non-specified dual-edge card types

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections
• Telecommunications equipment interface modules
• Test and measurement instrument backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and board thickness specifications. Confirm that the selected variant matches the necessary current and voltage ratings for the target application environment. Cross-reference the part number with the latest EDAC documentation to validate availability and compliance status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for panel-mounted applications. Ensure the host PCB design accommodates the specified nominal thickness of 1.57 mm. Consider the 5 A current rating and thermal operating limits when evaluating suitability for high-density interconnect scenarios within the 305 series family constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations for standard card edge applications. The series is characterized by its reliable gold-plated contacts and thermoplastic housing, widely used in industrial and commercial electronics where stable electrical performance and mechanical durability are critical for long-term operation.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and row count but different position numbers, such as 305-020-520-508 or 305-030-520-508, provided the physical footprint and electrical ratings remain compatible with the existing design requirements.
