305-086-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-278 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 86 positions in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and offers a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board alignment
Features a low profile insulator body constructed from thermoplastic polyester
Provides high dielectric strength with a 1800 VACrms insulation voltage rating

Edgeboard Connectors Applications

Computing and storage system interconnects
Medical device hardware connections
Aerospace and industrial control panels
Communications network infrastructure

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact contact plating thickness and insulator color variant, as these attributes may vary within the 305 series product line. Ensure that the selected polarizing key type matches the mechanical requirements of the target printed circuit board design before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with a 3.96 mm pitch is required for thick PCBs up to 1.57 mm. The 5 A current rating supports moderate power distribution needs. Consider the vertical panel mount style for rigid structural integration where space constraints favor a low-profile insulator body design.
