305-078-521-507

Edgeboard Connectors Overview

The EDAC 305-078-521-507 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 78 positions arranged in two rows with a contact spacing 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). Contacts are made of copper alloy with gold plating and utilize a solder pin termination type. The insulator body is constructed from thermoplastic polyester, providing an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with low profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Compatible with double-sided non-specified card edge PCBs

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct flange and termination specifications. Confirm that the target PCB thickness falls within the acceptable range of 1.37 mm to 1.78 mm. Check current availability status as distribution may vary by region. Ensure compliance with RoHS3 requirements if applicable to the project environment.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 78 positions is required in a vertical orientation. The 3.96 mm pitch allows for robust mechanical stability compared to finer pitches. Consider the gold plating for environments requiring corrosion resistance. Verify that the panel cutout dimensions align with the specified flange characteristics for secure installation.
