305-054-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-054-500-503 is a standard card edge connector from the 305 series, designed for dual-edge card applications. It features 54 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts rated for 5 A continuous current. Termination is achieved via solder eyelets, and the housing is constructed from green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting dual-edge card insertion
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic housing providing structural integrity
• Solder eyelet termination method for secure panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring high-density connections
• Telecommunications equipment backplanes
• Computing hardware motherboards and expansion cards

Edgeboard Connectors Procurement Notes

Verify the specific contact finish thickness and insulation resistance values against the official manufacturer datasheet prior to procurement. Confirm that the solder eyelet termination style aligns with the assembly process requirements. Ensure the thermoplastic housing material meets environmental standards for the intended operating temperature range of -40 C to +105 C.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 54 positions is required. The 3.96 mm pitch accommodates standard board layouts, while the 5 A rating suits moderate power distribution needs. Verify compatibility with polarizing keys if between-contact or in-key configurations are necessary for the system design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles, maintaining consistent pitch and current ratings across models. The 305-054-500-503 specifically addresses applications needing a 54-position dual-row interface with robust electrical performance.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 series variants such as 305-054-500-278 or 305-054-556-278 for alternative termination or housing options. Ensure substitute parts maintain the same 3.96 mm pitch and 54-position count to preserve mechanical fit.
