306-018-400-158

Edgeboard Connectors Overview

The EDAC Inc. 306-018-400-158 is a dual-edge female card edge connector from the 306 series, designed for panel and through-hole mounting. It features 36 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes tin-plated cantilever contacts on a green thermoplastic polyester insulator. It accepts non-specified dual-edge cards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit operates within a temperature range of -40°C to 105°C and includes flange features for flush installation with top openings and M3 threaded inserts.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable signal transmission
• Thermoplastic polyester insulator body providing thermal stability and chemical resistance
• Panel mount design with integrated flange featuring top openings and threaded inserts for secure mechanical fixation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment utilizing standard card edge modules
• Consumer electronics assemblies needing durable panel-mounted connectors

Edgeboard Connectors Procurement Notes

Verify that the replacement card edge PCB matches the specified thickness range of 0.054 to 0.070 inches to ensure proper contact engagement. Confirm the required flange hardware corresponds to the M3 threaded insert specification. Ensure the application environment remains within the rated operating temperature limits of -40°C to 105°C for long-term reliability.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 36-position interface is required for non-specified dual-edge cards. The choice is driven by the need for through-hole panel mounting with integrated securing features. Consider the tin plating for cost-effective applications where high corrosion resistance is not critical compared to gold alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which provides standard card edge connectors for various industrial and commercial applications. The series offers multiple position counts and contact spacing options to accommodate different board densities. The 306-018-400-158 specifically addresses needs for medium-density dual-edge connections with robust mechanical mounting capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series parts with identical pin counts and spacing, such as the 306-018-420-158, provided the contact plating and flange specifications match the original design requirements.
