306-018-400-178

Edgeboard Connectors Overview

The EDAC Inc. 306-018-400-178 is a standard card edge connector receptacle designed for single-side board insertion. It features 18 positions with a 3.96 mm (0.156 inch) contact spacing and accommodates a nominal PCB thickness of 1.57 mm. The component utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. Rated for 5 A current, it supports panel mount installation in a straight orientation with solder lug termination. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts single-sided printed circuit boards with a nominal thickness of 1.57 mm
• Features low-profile insulator body construction for compact integration
• Utilizes gold-plated copper alloy contacts for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card-edge interfaces
• Communication equipment backplanes
• Medical device internal module connections
• Energy management system interface cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact pin count, plating specifications, and mounting style compatibility. Ensure the target application requires the 3.96 mm pitch and 1.57 mm board thickness tolerance. Confirm that the thermoplastic polyester material meets the thermal requirements of the intended environment before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-current connection is required for thick PCBs. The 3.96 mm pitch provides ample spacing for higher voltage isolation compared to finer pitches. Consider the panel mount configuration if the connector serves as a fixed interface point rather than a sliding slot. Verify that the straight orientation aligns with the mechanical layout constraints of the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 306 series is characterized by its use of thermoplastic materials and standardized dimensions, ensuring compatibility across multiple industrial and commercial hardware platforms.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical 18-position configurations and 3.96 mm pitch, such as the 306-015-520-178 for different mounting variations. Cross-series replacements require matching the 1.57 mm board thickness acceptance and 5 A current rating to maintain electrical performance integrity.
