305-082-556-208

Edgeboard Connectors Overview

The EDAC 305-082-556-208 is a standard card edge connector featuring 82 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component provides a continuous current rating of 5 A and withstands 1800 VACrms. It employs gold-plated copper alloy contacts with surface mount solder terminals, housed in a green thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low profile insulator body design for compact integration
• Supports dual-edge connection configuration with female half-beadlock contacts

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal type and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the panel mounting style aligns with the mechanical assembly requirements. Cross-reference the manufacturer's datasheet for precise dimensional tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a high pin count interface is required within a standard 3.96 mm pitch framework. The dual-row configuration maximizes connectivity density while maintaining reliable signal integrity. Consider the surface mount termination method for automated assembly processes. Evaluate the thermal operating range against the intended application environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for demanding environments. Similar models in the lineup vary primarily in position count and row configuration while maintaining consistent electrical ratings and mechanical interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 82-position counts. Verify that alternative part numbers maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance criteria to ensure mechanical interchangeability.
