305-082-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-082-555-208 is a standard card edge connector featuring 82 positions arranged in a dual row configuration. 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 employs gold-plated copper alloy contacts for reliable signal transmission and supports a continuous current rating of 5 A. Designed for vertical panel mounting, it offers an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration designed for double-sided card edge insertion
• Vertical panel mount style with solder lug termination for secure PCB attachment
• Gold-plated copper alloy contacts ensure durability and low contact resistance
• Compatible with polarizing keys for precise board alignment during installation

Edgeboard Connectors Applications

• Industrial control system backplanes requiring high-density interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the vertical panel mount style aligns with the enclosure design constraints. Check for RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count interface with robust mechanical stability is required. The 3.96 mm pitch accommodates larger traces compared to finer pitches. The dual-row layout maximizes connection density within a limited footprint. Consider the 5 A current rating for power distribution needs alongside signal lines.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles to support diverse electronic assembly needs. The 305 series is characterized by its reliability in demanding environments and standardized mechanical dimensions for easy integration into existing designs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-080-555-568 for similar form factors. Verify pin count and pitch compatibility before substitution. Ensure that any alternative part maintains the same current rating and temperature specifications.
