305-030-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-030-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 30 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and employs a half-beam contact type for secure mating. Rated for 5 A continuous current and 1800 VACrms dielectric voltage, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Features half-beam female contacts with gold plating for reliable signal transmission
• Constructed with thermoplastic polyester insulation for durability and environmental resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement devices needing high-density vertical connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and termination style. Confirm compatibility with polarizing keys if mechanical locking is necessary for the assembly. Ensure the host PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper contact engagement. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with a 3.96 mm pitch is required for panel mounting. The 30-position count suits moderate density applications. Consider the 5 A rating and 1800 VACrms isolation for power and signal integrity needs. Verify that the vertical installation angle aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent electrical ratings and material specifications. The 305-030-556-203 variant specifically addresses dual-edge applications with solder pin termination and panel mount flanges.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series variants such as 305-020-556-202 or 305-048-556-508 for different position counts. Ensure any substitute maintains the 3.96 mm pitch and dual-edge configuration. Verify that the replacement part supports the same polarizing key requirements and current ratings.
