305-054-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-268 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 54 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, while the insulator body is made of green thermoplastic polyester. It supports a wide operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 54 positions for high-density board interconnection
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator provides durability and thermal stability
• Vertical panel mount design facilitates secure structural installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB form factors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical variations such as flange type or mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the dual-edge female contact configuration matches the system requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution is required for dual-edge cards. The 3.96 mm pitch accommodates standard board layouts, while the 5 A rating suits moderate power applications. Consider the -40°C to +105°C range for environments with significant thermal fluctuations. Confirm that the gold plating meets the necessary cycle life expectations for the intended mating cycles.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which offers various position counts and mounting options. The series is characterized by its low-profile insulator body and versatile installation styles, including panel mount configurations. It serves as a reliable interface between flexible or rigid PCBs and backplanes or chassis-mounted headers in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative part numbers with different position counts or mounting styles. Verify that any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure electrical ratings and material compositions match the original design specifications.
