306-016-420-178

Edgeboard Connectors Overview

The EDAC Inc. 306-016-420-178 is a standard card edge connector from the 306 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 32 positions and a pitch of 0.156 inches (3.96 mm). The connector supports a board thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm) and utilizes gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance. Rated for 5 A current, it employs a thermoplastic polyester housing and offers vertical through-hole termination for secure panel mounting.

Edgeboard Connectors Feature Summary

• Dual female contact configuration ensures robust mating with double-sided card edge PCBs.
• Gold-plated copper alloy contacts provide durable electrical connections with low contact resistance.
• Thermoplastic polyester housing delivers mechanical stability and thermal resilience across operating temperatures.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure compatibility with required flange styles and termination types. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the datasheet dimensions to validate fitment within the target enclosure constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 32-position interface is required for vertical panel mounting applications. Ensure the host PCB thickness falls within the specified 1.37 to 1.78 mm range to guarantee proper contact engagement. Consider the 5 A current rating and 105 C maximum operating temperature when evaluating thermal management requirements for the specific assembly environment.
