306-021-400-108

Overview

The EDAC Inc. 306-021-400-108 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a dual female configuration with 42 positions and a 0.156-inch (3.96 mm) pitch. The connector utilizes cantilever contacts made of copper alloy with gold plating, rated for 5 A current. It supports board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration for reliable signal transmission
• Cantilever spring contact design ensures secure mating force
• Flush mount flange with top opening and threaded insert for stability

Applications

• Industrial control systems requiring robust panel mounting
• Test and measurement equipment interfaces
• Communication hardware backplanes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, pitch, and termination style match project requirements. Ensure compatibility with the target PCB thickness and mounting hole specifications before procurement.

Selection Notes

Select this component when a dual-sided card edge interface with threaded panel mounting is required. The 0.156-inch pitch and 42-position layout suit high-density applications. Confirm that the cantilever contact type aligns with the mechanical insertion forces of the mating card.

Part Context

This part belongs to the EDAC 306 series of card edge connectors, which are characterized by thermoplastic polyester insulators and various mounting options. The series offers multiple row configurations and contact finishes to accommodate diverse electronic interconnection needs in harsh environments.

Replacement Considerations

Cross-reference with EDAC 316-021-400-108 for similar form factors. Verify exact dimensional tolerances and electrical ratings against alternative suppliers' datasheets to ensure functional equivalence.
