305-034-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-034-520-203 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 34 positions with 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 connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing durability and electrical insulation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body for compact panel integration
• Utilizes half-beam contact type for robust mechanical retention

Edgeboard Connectors Applications

• Industrial control panels requiring polarized card edge connections
• Vertical panel-mounted electronic modules
• High-reliability communication equipment interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact configuration and insulation material. Confirm compliance with RoHS3 and REACH regulations as specified by the manufacturer. Ensure the selected variant supports the intended PCB thickness and polarizing key requirements for your application design.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and 1800 VACrms dielectric strength for appropriate electrical isolation. Verify compatibility with existing polarizing key systems if board orientation security is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations while maintaining consistent 3.96 mm spacing. These connectors are engineered for high-density applications where reliable vertical interconnection between a card edge and a backplane or panel is necessary.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-034-520-204 or 305-034-520-503 for alternative contact plating or packaging options. Ensure substitute parts maintain the same 3.96 mm pitch and 1.57 mm board thickness compatibility.
