305-080-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-080-521-504 is a dual-edge female card edge connector with 80 positions and a 0.156-inch (3.96mm) pitch. It features gold-plated contacts, a green thermoplastic polyester insulator, and a half-bevel contact type. Designed for panel mount or through-hole installation, it supports PCB thicknesses of 0.054 to 0.070 inches. The connector operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides a 5A continuous current rating and 1800VACrms dielectric strength
• Features a flange with flush mounting, top opening, and threaded inserts

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct pin count, termination style, and flange configuration. Confirm that the application environment remains within the specified -40°C to 105°C operating temperature range. Check for compatibility with required polarizing keys if mechanical locking is necessary for the assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 80-position interface is required with a 0.156-inch pitch. Ensure the host PCB design accommodates the specified thickness range of 0.054 to 0.070 inches. Consider the panel mount requirement and verify that the available space allows for the threaded flange installation method.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options to suit different density requirements. Components in this family share common material properties and environmental ratings, ensuring consistent performance across different configurations within the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical electrical specifications but different pin counts or pitches. Cross-compatibility with other manufacturers requires verification of mechanical dimensions, contact geometry, and insulation material properties.
