305-050-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-502 is a dual-edge female card edge connector with 50 positions and a 0.156-inch (3.96mm) contact spacing. It features gold-plated contacts, a green thermoplastic polyester insulator, and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. Designed for panel mounting, this component operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Provides a 5A continuous current rating with 1800VACrms insulation capability
• Features low-profile insulator body construction for compact integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-sided PCBs
• Test and measurement devices needing reliable high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct flange and termination specifications. Confirm that the required polarizing key type matches the application needs, as these are often sold separately or specified uniquely. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this model when a 50-position dual-edge interface with 0.156-inch spacing is required. Ensure the target PCB thickness falls within the 0.054 to 0.070-inch range for proper mechanical engagement. Consider the panel mount style and verify that the operating temperature environment stays within the -40°C to 105°C specification limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, designed for general-purpose interconnect applications. The 305 series is known for its compatibility with standard double-sided PCBs and provides reliable electrical performance in industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or flange configurations. Cross-reference compatible polarizing keys if mechanical locking is required. Verify that alternative connectors maintain the same 0.156-inch spacing and PCB thickness acceptance criteria.
