305-022-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-022-556-512 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual-edge female configuration with 22 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates board thicknesses within the 1.37 mm to 1.78 mm range. Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A and an insulation resistance of 5 GOhms. The thermoplastic polyester housing ensures durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure mating with non-specified double-sided circuit boards
• Gold-plated copper alloy contacts ensure reliable electrical performance and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and thermal stability
• Panel mount vertical installation style facilitates robust mechanical integration

Edgeboard Connectors Applications

• Industrial control systems requiring durable panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable signal transmission
• Automotive electronics modules demanding stable connection under varying temperatures

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and housing color specifications. Ensure compatibility with target PCB edge thickness ranges before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel mounting orientation and termination type for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 22-position interface is required for panel-mounted applications. The 3.96 mm pitch suits standard board layouts, while the 5 A rating supports moderate power signals. Consider the -40°C to +105°C operational range for environments with significant thermal fluctuations. Verify that the gold-plated contacts meet the necessary conductivity requirements for the specific signal types involved.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate diverse design needs. The 305-022-556-512 specifically addresses applications requiring a compact, high-reliability connection point for double-sided circuit boards in panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-022-556-202 or 305-022-556-568 for similar form factors. Ensure that any substitute maintains the same 22-position count, 3.96 mm pitch, and dual-edge female configuration. Verify that alternative parts match the required current rating and operating temperature range.
