305-082-521-202

Edgeboard Connectors Overview

The EDAC 305-082-521-202 is a standard card edge connector receptacle featuring 82 positions with dual-edge contact configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts to ensure reliable signal transmission and includes a green thermoplastic polyester insulator body. Designed for panel mount installation, this series offers a low-profile form factor suitable for dense electronic assemblies requiring robust mechanical retention.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified board types
• Gold-plated copper alloy terminals provide corrosion resistance
• Low-profile thermoplastic polyester insulator body
• Panel mount orientation for secure vertical integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronics modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the dual-edge receptacle style matches the mating card edge profile requirements for the intended assembly application.

Edgeboard Connectors Selection Notes

Select this component when high current capacity and durable mechanical connection are required for thick PCB applications. The 3.96 mm pitch allows for wider trace spacing compared to finer pitches, reducing crosstalk risks in high-density layouts. Verify that the panel mount style aligns with the chassis design constraints and available mounting space within the enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in heavy-duty card edge connectors designed for demanding environments. The series is characterized by its robust construction and ability to handle significant mechanical stress during insertion and removal cycles. It serves as a critical interface between modular circuit cards and system backplanes or chassis panels.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical 82-position counts and 3.96 mm pitch. Verify that alternative suppliers offer components with matching row spacing and insulator height dimensions to ensure physical interchangeability without modifying the host panel structure.
