305-034-556-558

Edgeboard Connectors Overview

The EDAC Inc. 305-034-556-558 is a standard card edge connector header featuring 34 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for panel mounting at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high dielectric strength with a 1800 VACrms voltage rating

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard thickness PCBs
• Test and measurement instrumentation needing reliable dual-edge connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style and housing color before ordering. Confirm compatibility with existing polarizing key requirements if mechanical locking is necessary. Ensure the target application operates within the specified temperature range of -40 C to +105 C. Check regional availability as distribution may be restricted in certain areas.

Edgeboard Connectors Selection Notes

Select this model when a dual-row connection is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications where space efficiency is balanced with high pin counts. Consider the gold-plated contacts for environments demanding corrosion resistance. Verify that the vertical panel mount style 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 provides various position counts while maintaining consistent electrical characteristics and mechanical dimensions. It is designed for use in headers where durability and precise alignment are critical for system performance.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-034-556-258 and 305-034-520-558. These alternatives share identical mechanical specifications but may differ in termination type or housing color. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness acceptance.
