305-050-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-050-500-578 is a standard card edge connector designed for dual-edge PCB mounting. It features 50 positions with a 3.96 mm (0.156 inch) contact spacing and accepts boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A continuous current, it supports vertical panel installation with solder lug termination.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing
• Gold-plated contacts ensure reliable conductivity
• Accepts polarizing keys for secure board alignment

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Test and measurement instruments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation color. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the selected variant matches the required current rating and voltage isolation specifications for the intended circuit environment.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with 50 positions is required. Verify that the application allows for vertical panel mounting. Ensure the mating PCB design accommodates the 3.96 mm pitch and 1.57 mm nominal thickness. Check if in-contact or between-contact polarizing keys are needed for assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various position counts and termination styles. The series provides standardized dimensions for industrial card edge applications. Other variants in the family differ primarily in pin count and housing material properties while maintaining consistent electrical ratings.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts having identical 50-position layouts. Verify mechanical fit within existing chassis constraints. Ensure replacement connectors support the same thermal operating range from -40°C to +105°C.
