305-054-556-558

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-558 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 54 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector accepts dual-edge non-specified cards with a thickness range of 1.37 mm to 1.78 mm. Contact plating is gold over copper alloy, providing a continuous current rating of 5 A and an insulation resistance of 5 GOhms. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-edge female contact design ensures reliable signal transmission
• Thermoplastic insulator housing provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct pin count, termination style, and plating specifications. Confirm that the required card thickness falls within the specified tolerance range before integration. Cross-reference the RoHS compliance status with current regulatory requirements for your target market.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with a 3.96 mm pitch is required for panel-mounted assemblies. Ensure the mating card supports dual-edge insertion and verify that the 5 A current rating meets the circuit load requirements. Consider the vertical mounting angle and panel cutout dimensions during mechanical design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and termination options. The series is characterized by its durable thermoplastic construction and gold-plated contacts, suitable for demanding environments. Similar parts in the series include different row counts and termination styles such as solder lugs or pins.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with identical 54-position configurations but different termination methods. Verify mechanical compatibility and electrical ratings before swapping with connectors from other manufacturers.
