305-070-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-070-555-212 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 70 positions with a contact pitch of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A. The unit utilizes a low-profile thermoplastic insulator body and employs solder lug termination for secure panel mounting.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting dual-edge card insertion
• Gold-plated copper alloy contacts for reliable signal transmission
• Low-profile insulator body design for space-constrained environments
• Solder lug termination method for robust panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Communication equipment backplanes and modules
• Medical device internal circuit board connections
• Consumer electronics mainboard interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required board thickness and termination style. Confirm that the dual-edge specification matches the target PCB design. Check regional availability as distribution status may vary by location. Ensure RoHS compliance requirements are met for the intended application environment.

Edgeboard Connectors Selection Notes

Select this model when a 70-position dual-row interface is required for 0.062-inch thick boards. The 3.96 mm pitch suits applications needing moderate density without excessive miniaturization. Consider the solder lug termination if panel mounting is preferred over surface mount alternatives. Verify thermal operating ranges against system environmental conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options tailored for diverse electronic assembly needs. The 305 series is widely recognized in industrial and commercial sectors for its durability and standardized dimensions, facilitating easy integration into existing hardware architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-070-555-512, which shares identical dimensional and electrical characteristics but may differ in insulator color. Cross-series replacements require careful verification of pitch, row spacing, and board thickness compatibility to ensure mechanical fit.
