305-020-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-208 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features 20 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. It supports vertical installation and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides high insulation resistance of 5 GOhms
• Features half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connections
• Industrial control systems utilizing standardized card edge interfaces
• Equipment needing polarized keying options for connector alignment

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required panel mount orientation and contact termination style for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 20-position card edge interface is required for panel mounting. Consider the 3.96 mm pitch and compatible board thickness range during mechanical design. Verify that the 5 A current rating meets circuit requirements. Ensure the application benefits from polarizing key acceptance if precise insertion alignment is critical for the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-020-555-208 specifically denotes a 20-position dual-row unit with panel mount characteristics. It shares common electrical ratings with other series members but differs in physical configuration and terminal type.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes. Compatible alternatives may include variants with identical pitch and position counts but different mounting styles or termination types. Verify mechanical envelope compatibility before substitution.
