305-050-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-202 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 50 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and solder pin termination. It is rated for 5 A continuous current and supports PCB thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The insulator is made of green thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low-profile insulator body with a flange for flush mounting
• Utilizes semi-waffle spring contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module formats
• Test and measurement devices needing high-density vertical connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct contact plating, insulation color, and flange specifications. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical performance during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 50-position interface is required for vertical panel mounting. Ensure compatibility with the 0.156-inch pitch standard. Consider the 5 A current rating and 1800 VACrms dielectric strength for appropriate voltage and load handling. Verify that the application environment remains within the -40°C to +105°C operational temperature limits defined by the thermoplastic polyester material.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their .156-inch contact spacing and acceptance of nominal .062-inch thick PCBs. The series offers various position counts and configurations, providing a versatile solution for connecting edge-board modules to backplanes or chassis-mounted headers in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or insulation colors. Cross-reference compatible parts from other manufacturers only if they strictly match the 3.96 mm pitch, dual-row layout, and vertical panel mount form factor.
