305-026-500-268

Edgeboard Connectors Overview

The EDAC Inc. 305-026-500-268 is a standard card edge connector from the 305 series, designed for dual female board-to-board applications. It features 26 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, housed in a green thermoplastic polyester insulator. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual edge female configuration for secure mating with double-sided PCBs
• Low profile insulator body design for compact assembly requirements
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Accepts between-contact and in-contact polarizing keys for alignment

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Computer peripheral interface modules
• Test and measurement instrumentation cards

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified partners. Confirm RoHS compliance status via official datasheets prior to integration. Ensure storage conditions maintain integrity of gold plating and thermoplastic housing. Validate mechanical dimensions against target PCB layout specifications to guarantee proper fit and electrical performance during procurement.

Edgeboard Connectors Selection Notes

Select this model when dual-row connectivity with 3.96 mm pitch is required for 1.57 mm thick boards. Consider the 5 A current rating and 105°C thermal limit for operational environments. Verify compatibility with polarizing key systems if positional accuracy is critical. Compare against single-row alternatives if space constraints differ from dual-edge requirements.

Edgeboard Connectors Part Context

Part of the EDAC 305 series, which provides robust card edge solutions for high-reliability applications. The series emphasizes durable construction with thermoplastic polyester housings and gold-plated contacts. This specific model represents a standard dual-female variant optimized for vertical panel mounting or direct board stacking scenarios within electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing identical 26-position count, 3.96 mm pitch, and dual female configuration. Verify matching board thickness acceptance and current ratings before substitution. Ensure physical footprint and polarizing key compatibility align with existing mechanical designs.
