305-028-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 28 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports a continuous current rating of 5 A and withstands 1800 VACrms. The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and employs a solder lug termination style for secure panel mounting.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Low profile insulator body design for compact integration
• Dual female contact configuration for non-specified card edge boards

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module connections
• Telecommunications hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange dimensions. Confirm that the target PCB thickness aligns with the 0.062-inch nominal requirement. Ensure compatibility with required polarizing key types before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with 28 positions and 3.96 mm spacing is required. The 5 A current rating and 1800 VACrms insulation voltage suit moderate power applications. Verify that the solder lug termination style matches the assembly process and panel mounting constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles. The 305-028 variant specifically addresses needs for 28-position dual-edge connections with robust electrical ratings and polarizing key acceptance capabilities.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts like 305-024 or 305-032 if position count adjustments are needed. Verify identical flange and mounting hole specifications before substituting.
