305-052-556-278

Edgeboard Connectors Overview

The EDAC 305-052-556-278 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features a dual-row configuration with 52 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accommodates 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 constructed from copper alloy with gold plating, while the insulator body is made of thermoplastic material. Operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, row configuration, and termination type. Ensure compatibility with target PCB thickness and mounting hole patterns. Confirm RoHS compliance status through manufacturer datasheets prior to procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate environmental ratings match operational requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge solution with 3.96 mm pitch is required. Consider the 5 A current rating and thermal performance limits for load management. Evaluate panel mounting constraints against available space. Compare alternative series if different board thicknesses or contact materials are needed. Ensure the vertical orientation aligns with system mechanical design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting options. The series is characterized by low-profile insulator bodies and standardized spacing. Similar models in the series may differ in terminal count or flange configurations. The 305 series supports both single and double-sided card edge applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical 52-position dual-row layouts and 3.96 mm pitch. Verify mechanical dimensions and electrical ratings before substitution. Alternative manufacturers may offer compatible connectors but require full dimensional and electrical validation.
