305-056-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-201 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 56 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). It utilizes copper alloy contacts with gold plating and offers a current rating of 5 A. The unit employs a solder pin termination style and is housed in a green thermoplastic insulator.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting dual-edge card insertion
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic insulator body providing electrical insulation
• Solder pin termination for secure panel or board mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces
• Computer peripheral expansion modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required board thickness and mounting style. Confirm that the gold plating specification meets environmental requirements. Check RoHS compliance status against project regulations. Ensure the 56-position count aligns with the target PCB design. Validate the 3.96 mm pitch against existing mechanical constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface is required with high pin counts. The 3.96 mm pitch suits applications needing wider spacing between signals. Consider the 5 A current rating for power distribution needs. The vertical mounting style fits panel-mounted configurations. Verify that the 1.57 mm board thickness matches the target PCB specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of card edge connectors, which provides various mounting options and position counts. The series is characterized by its low-profile insulator body and standardized dimensions. It serves as a reliable solution for connecting double-sided edge cards to system backplanes or chassis panels.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the 305 Series include parts with identical pitch and position counts but different mounting styles or plating options. Cross-reference the 305-056-520-201 for similar specifications. Ensure any replacement maintains the 3.96 mm spacing and 56-position requirement.
