833-078-521-804

Edgeboard Connectors Overview

The EDAC Inc. 833-078-521-804 is a standard card edge connector from the 833 series, designed for panel mounting applications. It features 78 positions with a 3.96 mm pitch and accommodates a board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and a Diallyl Phthalate (DAP) housing. It supports a current rating of 3 A and operates within a temperature range of -40 C to +125 C. The unit employs solder pin termination and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for reliable signal transmission.
• Panel mount installation style with right-angle orientation for efficient space utilization.
• High-temperature Diallyl Phthalate (DAP) insulator construction for thermal stability.

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Medical interconnect solutions demanding high reliability
• Agricultural technology equipment operating in harsh environments

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC channels or certified distributors. Confirm that the specific suffix matches the required dual-row specification and right-angle orientation. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the solder pin termination aligns with the assembly process requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The choice is appropriate for designs needing a 78-position interface with gold-plated contacts and high-temperature resistance up to 125 C. Consider the right-angle form factor for spatial constraints and ensure the DAP housing material meets environmental durability standards.

Edgeboard Connectors Part Context

This component belongs to the EDAC 833 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections.
