306-018-521-158

Edgeboard Connectors Overview

The EDAC Inc. 306-018-521-158 is a dual-sided female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 18 positions with a 0.156-inch (3.96mm) contact spacing and a double-row configuration. The connector utilizes gold-plated cantilever contacts on a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit includes a flange with top opening and threaded inserts for secure installation.

Edgeboard Connectors Feature Summary

• Dual-sided female contact configuration for reliable board insertion
• Gold-plated cantilever spring contacts ensure stable electrical connection
• Panel mount design with integrated flange and threaded insert provisions
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device internal board connections
• Agricultural technology equipment modules
• General-purpose electronic assembly integration

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 18-position count and 0.156-inch pitch before ordering. Confirm that the target PCB thickness falls within the specified 0.054 to 0.070-inch range to ensure proper mechanical fit. Check for RoHS compliance requirements if the application demands restricted substance adherence. Ensure the mounting environment supports the operating temperature range of -40°C to 105°C.

Edgeboard Connectors Selection Notes

Select this component when a high-reliability, dual-sided card edge interface is required with a 3.96mm pitch. The cantilever contact type offers ease of insertion compared to wire-wrapped alternatives. Consider the panel mount flange feature if space-constrained vertical mounting is necessary. Verify that the green color coding aligns with any existing visual identification schemes in the assembly.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series is known for robust construction suitable for harsh environments, including medical and agricultural applications. The 306-018-521-158 variant specifically addresses the need for 18-position connectivity with a wide contact spacing, distinguishing it from finer-pitch alternatives in the broader EDAC portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other position variants such as the 306-007-521-158 or 306-030-521-158, provided the pin count difference is acceptable. Cross-series replacements require careful verification of pitch, board thickness tolerance, and mounting hole alignment to maintain mechanical integrity.
