305-048-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-048-500-278 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual-row configuration with 48 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm. This header utilizes solder pin termination and accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The unit provides a continuous current rating of 5 A and supports an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body made of thermoplastic polyester
• Designed for vertical panel mounting with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement devices needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 48-position dual-row configuration before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure that the gold-plated copper alloy contacts meet the environmental requirements of the final assembly. Review the datasheet for precise mounting dimensions and thermal operating limits.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-row connector is required for panel-mounted applications. It is suitable for designs specifying a 1.57 mm board thickness and a 5 A current rating. Consider the 305 series if polarizing key acceptance is necessary for board retention. Verify that the green thermoplastic housing material aligns with the aesthetic or regulatory needs of the project. Compare against similar EDAC models like the 315 series if different mounting styles are preferred.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various mounting options and position counts. The series is characterized by its .156 inch contact spacing and compatibility with standard double-sided card edge connectors. Similar parts in the lineup include the 305-048-500-201 and 305-048-520-268, differing primarily in packaging or specific suffix variations. The 305 series is widely used in industrial and commercial electronics for stable interconnection.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC family include the 305-048-500-201 and 305-048-520-268. These alternatives share the same core specifications but may differ in packaging or minor suffix details. Ensure that any replacement maintains the 48-position count and 3.96 mm pitch. Verify that the alternative part supports the same 1.57 mm board thickness and panel mounting style.
