305-050-555-278

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-278 is a dual female card edge connector from the 305 series, designed for board edge or panel mount applications. It features 50 positions with a 0.156-inch (3.96mm) contact spacing and .140-inch row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contact surfaces are gold-plated copper alloy with a half-bellows termination style, ensuring reliable soldering. The insulator body is made of thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Low profile insulator body design
• Gold-plated half-bellows contact termination
• Accepts standard 0.062 inch PCB thickness

Edgeboard Connectors Applications

• Panel mount interconnect systems
• Board edge signal routing
• Industrial control module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's current ordering guide to confirm plating thickness and flange specifications. Ensure the target PCB thickness aligns with the 0.062-inch nominal requirement. Confirm RoHS compliance status through official documentation prior to integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for 0.062-inch thick boards. The 0.156-inch pitch suits general-purpose signal applications. Verify that the mounting style matches the mechanical constraints of the enclosure panel.

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 configurations. The 305-050 variant specifically provides 50 contacts in a dual arrangement, balancing density with standard spacing requirements.

Edgeboard Connectors Replacement Considerations

Cross-reference the 305-050-556-502 and 305-050-556-201 models for similar 50-position dual female configurations. Verify dimensional compatibility and flange diameter differences before substitution.
