305-040-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-512 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 40 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes female contacts made of copper alloy with gold plating and employs a solder pin termination method. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, accommodating a board thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified dual-sided card insertion
• Vertical panel mount orientation with solder pin termination for secure PCB attachment
• Gold-plated copper alloy contacts ensuring reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulator providing structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Automotive electronics demanding high-temperature operational reliability
• Test and measurement instrumentation with standardized connector footprints

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact length, insulation color, and termination style variations. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before integration. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the vertical panel mount design aligns with the mechanical enclosure constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 40-position interface is required for vertical mounting configurations. The 3.96 mm pitch accommodates standard board layouts while maintaining electrical isolation. Consider the 5 A current rating and +105°C maximum operating temperature for environments with elevated thermal loads. Verify that the solder pin termination method matches the available assembly processes on the target manufacturing line.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability interconnection solutions. The series offers various position counts and termination options to support diverse electronic system designs. As a header-type connector, it provides a stable mechanical connection between the mainboard and plug-in modules, ensuring consistent electrical performance across industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same family include the 305-040-521-507 and 305-040-521-512 variants, which share identical positional and pitch specifications. Verify that any alternative part number maintains the same 40-position count, dual-row layout, and vertical mounting orientation to ensure mechanical interchangeability without redesigning the host enclosure.
