305-012-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-012-500-278 is a standard card edge connector header from the 305 series, designed for vertical panel mounting. It features a dual-row configuration with 12 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy with gold plating, rated for 5 A current. Termination is achieved via solder eyelets, and the insulator body is made of thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing high-density connectivity within a low-profile insulator body design
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Vertical panel mount style facilitates secure integration into chassis or enclosure systems

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific termination type and contact count against the official datasheet before procurement. Confirm that the target printed circuit board thickness matches the specified 1.57 mm requirement to ensure proper mechanical engagement. Check for RoHS compliance status if environmental regulations apply to the end product assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted applications. Ensure the design accommodates the 3.56 mm row spacing and supports the 5 A current rating per contact. Consider the vertical orientation and solder eyelet termination method for compatibility with the assembly workflow and PCB layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which offer various position counts and mounting options. The series is characterized by its 0.156-inch contact spacing and robust construction suitable for demanding environments. The 305-012-500-278 specifically provides a 12-position solution in a dual-row format.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with identical 12-position dual-row configurations and 3.96 mm pitch, such as the 305-012-500-202 or 305-012-500-204, provided they match the required termination style and mounting orientation.
