305-078-556-507

Edgeboard Connectors Overview

The EDAC 305-078-556-507 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 78 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy with gold plating and utilize a solder pin termination type. The insulator body is made of thermoplastic material.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm mechanical variations such as flange types or mounting hardware configurations. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the dual-row layout aligns with the system's routing requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate that the solder pin termination method matches the manufacturing process capabilities.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 78 positions is required within a limited panel space. The 3.96 mm pitch offers a balance between signal density and manufacturability. Consider the gold plating for environments where corrosion resistance is critical. Evaluate the thermal operating range of -40°C to +105°C against the application's environmental conditions. Ensure the panel mount style fits the enclosure design constraints.
