305-082-500-278

Edgeboard Connectors Overview

The EDAC Inc. model 305-082-500-278 is a standard card edge connector belonging to the 305 series. It features a dual-row configuration with 82 positions and a pitch of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and is designed for panel mounting in a vertical orientation. It supports solder pin termination and accommodates board thicknesses within the range of 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms and operating temperatures between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Vertical panel mount design with solder pin termination for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness and housing color specifications. Ensure that the target printed circuit board thickness falls within the specified mechanical tolerance range of 1.37 mm to 1.78 mm to guarantee proper mating engagement. Confirm compliance requirements such as RoHS status directly through authorized distribution channels prior to procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 82 positions is required. The 3.96 mm pitch dictates the trace spacing on the mating PCB. Verify that the application environment remains within the -40°C to +105°C operational temperature range. Consider the vertical panel mounting style if space constraints require a perpendicular connection relative to the chassis.
