305-014-556-278

Edgeboard Connectors Overview

The EDAC Inc. 305-014-556-278 is a standard card edge connector from the 305 series, designed for dual-side board insertion. It features 14 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and utilizes gold-plated copper alloy contacts rated for 5 A current. It employs a solder pin termination style for vertical panel mounting. The housing is constructed from green thermoplastic polyester, ensuring reliable insulation with a minimum resistance of 5 GOhms across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with female half-beadle contacts for secure card retention

• Thermoplastic polyester insulator provides robust mechanical support
• Vertical panel mount design with flanged installation capability

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Medical device signal processing boards
• Consumer electronics expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and material specifications. Ensure the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Confirm that the application environment remains within the -40°C to +105°C operational limits defined by the component's thermal rating.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge connection with a 3.96 mm pitch is required for vertical panel integration. The 14-position count suits moderate-density interconnect needs. Consider the gold plating for corrosion resistance in demanding environments. Verify that the thermoplastic housing material meets the dielectric requirements of the target circuitry before finalizing the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting options and row configurations. The series is characterized by its standardized 3.96 mm spacing and robust construction suitable for high-reliability applications. The 305-014 variant specifically addresses compact dual-row requirements within this established product family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 3.96 mm pitch and 14-position layout. Verify identical panel mounting dimensions and PCB thickness tolerances to ensure mechanical compatibility without redesigning the host enclosure or circuit board footprint.
