305-072-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-208 is a standard card edge connector receptacle featuring 72 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge cards, it utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. The component supports a PCB mount installation style at a straight angle, accommodating board thicknesses of 1.57 mm. It carries a 5 A current rating and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure mating with non-specified card edge boards
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulation provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control systems requiring robust peripheral interconnects
• Telecommunications equipment utilizing standardized card modules
• Automotive electronics demanding high-reliability board-to-board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact plating thickness and housing color specifications. Ensure compatibility with the target printed circuit board thickness and mounting hole dimensions prior to procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc.

Edgeboard Connectors Selection Notes

Select this component when a 72-position interface with a 3.96 mm pitch is required for dual-edge applications. Confirm that the straight-mount orientation aligns with the mechanical assembly constraints. Evaluate the 5 A current rating against the total load requirements of the connected circuitry to ensure safe operational margins under maximum ambient temperatures.
