307-040-554-178

Edgeboard Connectors Overview

The EDAC Inc. 307-040-554-178 is a standard card edge connector featuring 40 positions in a single row with a 3.96 mm (0.156 inch) pitch. Designed for panel mounting at a right angle, it utilizes solder lug termination. The contacts are gold-plated copper alloy rated for 5 A current, housed in green thermoplastic polyester. It supports board thicknesses of 1.37 mm to 1.78 mm and operates between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Right-angle panel mount design for secure structural integration
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester insulator providing thermal stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix configuration against official EDAC documentation to ensure correct locking mechanism and terminal style. Confirm that the target PCB or card edge thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical contact integrity during assembly.

Edgeboard Connectors Selection Notes

Select this component when a right-angle, panel-mount interface is required for high-density connections. Ensure the application environment remains within the -40°C to +105°C operational temperature limits. Verify that the 3.96 mm pitch aligns with the mating card edge layout and that the 5 A current rating meets the circuit requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series, which provides standardized card edge connectors for various industrial applications. The series offers multiple position counts and mounting styles, allowing for flexible system design while maintaining consistent mechanical and electrical performance characteristics across different configurations.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 307-series variants such as 307-040-522-203 for vertical mounting options. Ensure any substitute maintains the same 3.96 mm pitch and 40-position count to preserve mechanical fit and electrical compatibility without redesigning the host enclosure.
