305-072-500-212

Edgeboard Connectors Overview

The EDAC Inc. 305-072-500-212 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 made of copper alloy with gold plating, supporting a current rating of 5 A. The housing is constructed from green thermoplastic polyester, accommodating a board thickness of 1.57 mm. It operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Thermoplastic polyester housing provides thermal stability
• Solder termination style facilitates secure PCB integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Automotive electronic modules
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination type. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the gold contact finish meets the required corrosion resistance standards for the intended operational environment before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge interface is required for 72-position connections. The 3.96 mm pitch distinguishes it from finer-pitch alternatives. Consider the straight mounting angle and solder eyelet termination for standard vertical PCB assembly. Verify that the 5 A current rating aligns with the electrical load requirements of the application circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulators and gold-plated contacts. The 305 series generally supports various position counts and row configurations, offering a standardized solution for edgeboard applications across multiple industrial sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 72-position, dual-row, 3.96 mm pitch specification. Verify mechanical dimensions and electrical ratings match exactly. Ensure the replacement maintains the same solder termination style and housing material properties.
