305-050-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-208 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual female configuration with 50 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating and a green thermoplastic insulator body, it provides a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The unit supports solder lug termination and operates 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 alignment
• Features a low-profile insulator body with flush mount flange characteristics
• Utilizes semi-bellows contact type for reliable signal transmission

Edgeboard Connectors Applications

• Vertical panel mounted electronic assemblies

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style and flange configuration. Confirm compatibility with the target PCB thickness of 1.57 mm before procurement. Ensure the application environment remains within the specified operating temperature limits. Cross-reference the manufacturer's ordering guide to validate pin count and row arrangement requirements against the design specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted systems. The 50-position capacity suits moderate-density interconnect needs. Consider the gold-plated copper alloy contacts for corrosion resistance. Verify that the vertical orientation aligns with the mechanical layout constraints of the enclosure design.

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 options while maintaining consistent 3.96 mm spacing. The 305-050 variant specifically addresses designs requiring fifty connection points in a dual-row format. It shares common mechanical dimensions with other parts in the family but differs in terminal count and specific flange details.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-050-556-201 and 305-050-556-278. These alternatives share the same 50-position count and 3.96 mm spacing. Verify that the termination type and flange features match the existing assembly requirements before substitution.
