305-030-500-278

Edgeboard Connectors Overview

The EDAC Inc. model 305-030-500-278 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual-row configuration with 30 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and offers an insulation resistance of 5 GOhms. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Gold-plated contacts ensure reliable signal transmission
• Panel mount installation with solder eyelet termination

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Computer peripheral module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, flange characteristics, and color coding. Ensure the target PCB thickness aligns with the 1.57 mm nominal specification. Confirm RoHS compliance status through the latest environmental documentation provided by EDAC before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution with 3.96 mm pitch is required. The 30-position count suits moderate-density interface needs. Verify that the application environment stays within the -40°C to +105°C operational limits. Consider the thermoplastic polyester housing material for general-purpose durability and electrical insulation properties in standard industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series provides various position counts and mounting styles. The 305-030-500-278 specifically denotes a 30-position, dual-row variant with panel mount orientation. It serves as a robust interconnect solution for rigid board-to-board or board-to-backplane applications requiring high reliability.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 3.96 mm pitch and 30-position count. Verify mechanical dimensions and terminal type compatibility before substitution. Check for identical thermal ratings and contact material specifications to maintain performance integrity.
