305-082-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-512 is a standard card edge connector from the 305 series, designed for panel mount installation with through-hole solder termination. It features a dual female configuration with 82 positions and a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, providing a 5 A continuous current rating and 1800 VACrms insulation voltage. The housing is green thermoplastic polyester, supporting board thicknesses of 1.37 mm to 1.78 mm.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning.
• Features a dual female contact arrangement for non-specified card edge applications.
• Utilizes gold-plated copper alloy contacts for reliable signal transmission.

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffix codes to ensure correct contact plating, orientation, and mounting style. Confirm that the target PCB card thickness falls within the specified 1.37 mm to 1.78 mm range. Check for RoHS compliance status if required by project specifications. Ensure panel cutout dimensions match the flange characteristics for proper alignment.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge connector is needed for panel-mounted assemblies. The 3.96 mm pitch offers robust spacing for industrial environments. Consider the 5 A current rating for power distribution needs. Verify compatibility with polarizing key requirements if mechanical locking is necessary for the specific application design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides a range of card edge solutions for various industrial and commercial applications. The series is known for its durable thermoplastic polyester construction and reliable gold-plated contacts. Similar models in the series vary by position count and specific mounting configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching pin counts and pitch, such as the 305-082-521-202 or 305-082-520-512, provided the specific suffix variations align with the required orientation and termination style. Cross-brand replacements require strict verification of pitch, height, and electrical ratings.
