305-072-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-502 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of thermoplastic polyester, and the unit supports board thicknesses up to 1.57 mm. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester housing providing structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating thickness and housing color specifications. Confirm that the required board thickness falls within the supported range of 1.57 mm maximum. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for vertical PCB mounting. Ensure the mating card edge thickness aligns with the connector's mechanical constraints. Consider the 5 A current rating and 105°C thermal limit for environmental suitability. Verify that the straight mounting style fits the enclosure spatial requirements without interference.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations for diverse application needs. The 305 series is characterized by its robust thermoplastic construction and standardized 3.96 mm pitch, ensuring compatibility with industry-standard card edge designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 305 series designation, 72 positions, and dual-row layout, such as 305-072-520-204 or 305-072-521-202, provided mechanical and electrical parameters match exactly.
