305-026-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-208 is a standard card edge connector featuring 26 positions arranged in a dual-row configuration. It utilizes a contact spacing of 3.96 mm and a row spacing of 3.56 mm. Designed for panel installation, this vertical connector accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are gold-plated copper alloy, supporting a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The insulator body is constructed from thermoplastic material, ensuring reliable performance within an operating temperature range of -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 for compact integration
• Supports high-voltage isolation capabilities up to 1800VACrms

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instruments needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact pin count, plating type, and mounting style variations within the 305 series. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with existing PCB design specifications regarding board thickness and guide hole placement. Cross-reference datasheet revisions to validate current electrical ratings and environmental tolerances against project requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and 1800VACrms voltage capability for high-power or high-isolation needs. Evaluate the vertical orientation and solder lug termination against available board space and assembly constraints. Compare against single-row alternatives if reduced profile or different positioning is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, designed for general-purpose electronic interconnections. The series offers various position counts and termination options to accommodate diverse board sizes.
