305-026-520-508

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-508 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 48 positions arranged in two rows with a 3.96 mm pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. It supports a board thickness of 1.57 mm and offers a 5 A current rating. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides high dielectric strength with 1800VACrms capability
• Features semi-waffle spring contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Panel-mounted electronic modules needing robust vertical interconnects
• High-voltage signal routing in specialized instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific position count against project requirements, as datasheet discrepancies exist regarding 26 versus 48 positions. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement. Ensure the ordering suffix matches the exact plating and housing color specifications required for your assembly process.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount card edge connector with polarizing key compatibility is required. The 3.96 mm pitch and dual-row configuration suit applications needing high-density connections on thick PCBs. Verify that the 5 A current rating and 1800VACrms insulation meet the electrical demands of the target circuit design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its robust construction for industrial environments. Similar parts in the series vary primarily by position count and specific housing configurations while maintaining consistent electrical ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models like 305-026-520-501 and 305-026-520-578, which share similar form factors but may differ in housing color or specific plating details. Always verify mechanical dimensions and pin counts before substitution.
