305-064-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-064-500-278 is a dual-edge card edge connector from the 305 Series, designed for high-reliability applications. It features 64 positions with a 0.156-inch (3.96 mm) pitch and accepts between-contact or in-contact polarizing keys. The contacts are gold-plated copper alloy, rated for 5A continuous current and 1800VACrms insulation voltage. Constructed with green thermoplastic polyester insulators, it supports panel mount installation at a vertical angle. The component operates within a temperature range of -55°C to +125°C and utilizes solder pin termination.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and mounting configurations. Confirm that the selected variant matches the intended PCB thickness and contact termination style. Cross-reference the part number with the latest EDAC documentation to validate availability and compliance with current RoHS standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with a 3.96mm pitch is required for robust mechanical retention. Ensure the application environment does not exceed the specified operating temperature limits of the green thermoplastic polyester housing. Verify that the PCB design accommodates the necessary polarizing key slots if between-contact or in-contact positioning is utilized for the assembly process.
