305-020-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-502 is a dual-edge female card edge connector designed for vertical panel mounting. It features 20 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes gold-plated contacts on a copper alloy base, housed in a black thermoplastic insulator body. It supports a continuous current rating of 5A and withstands 1800VACrms dielectric voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Low profile insulator body design for compact assembly requirements
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance

Edgeboard Connectors Applications

• Vertical panel mount interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm insulation color and contact plating specifications. Ensure the target PCB thickness aligns with the 0.062-inch nominal requirement for proper mechanical engagement. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 20 positions is required for vertical panel installation. The 0.156-inch pitch accommodates standard board layouts. Consider the 5A current rating and 1800VACrms insulation capability for appropriate electrical isolation in the target application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-020-555-502 variant specifically provides a dual-edge female configuration suitable for robust vertical panel applications requiring polarizing key compatibility.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-020-555-501 or 305-020-555-508 if different insulation colors are needed. Verify that substitute parts maintain the same 0.156-inch pitch and 20-position count to ensure mechanical fit.
