305-016-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-016-500-278 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 16 positions with a 3.96 mm (0.156 inch) contact spacing and dual-edge female contacts. The connector utilizes gold-plated copper alloy terminals with solder lug termination. It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body constructed from thermoplastic material
• Dual-edge female contact design ensures reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing high-reliability signal paths

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal type and insulation color. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the required polarizing key configuration matches the application needs before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution is required for dual-edge cards. The 3.96 mm pitch suits applications needing wider spacing than standard connectors. Verify that the 5 A current rating meets the system's electrical requirements and that the operating temperature range aligns with environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. These connectors are engineered for durability in demanding environments, providing stable connections for electronic modules inserted into panel-mounted headers.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-016-500-558 and 305-016-556-504. Verify that alternative part numbers maintain identical pin count, pitch, and mounting style before implementation.
