306-022-521-112

Overview

The EDAC Inc. 306-022-521-112 is a single-sided card edge connector from the 306 Series, designed for vertical through-hole mounting. It features 22 positions with a contact spacing of 0.156 inches (3.96mm). The connector utilizes PC tail contacts with gold plating on the contact area and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The insulator body is green, providing a low-profile design suitable for dense electronic assemblies.

Feature Summary

• Single centerline row configuration for standard card edge applications
• Gold-plated PC tail contacts ensure reliable electrical connectivity
• Low-profile insulator body reduces overall assembly height
• Vertical through-hole mounting style for secure PCB attachment

Applications

• Medical interconnect solutions such as ventilators and CPAP machines
• Ambulance communication and monitoring systems
• General-purpose electronic board-to-board connections

Procurement Notes

Verify the specific ordering suffix to confirm contact type and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the vertical mounting orientation aligns with the mechanical design constraints of the final enclosure. Cross-reference the manufacturer's latest datasheet for any updates to material specifications or environmental ratings before finalizing procurement.

Selection Notes

Select this component when a single-row, 22-position interface is required with a 3.96mm pitch. The choice is appropriate for applications demanding gold-plated contacts for corrosion resistance. Consider the low-profile form factor if space constraints are critical. Ensure the vertical mounting style fits within the available board clearance and that the through-hole termination method matches the manufacturing process.

Part Context

This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series is characterized by its .156 inch contact spacing and robust construction for general industrial use. The 306 line offers various position counts and mounting options, positioning this model as a solution for mid-density interconnect needs within EDAC's broader portfolio of edgeboard connectors.

Replacement Considerations

Direct substitutes include other EDAC parts within the 306 series with matching pin counts, such as the 306-021-521-112 for different contact configurations. Verify that any alternative maintains the 0.156-inch pitch and single-sided design. Ensure mechanical dimensions, particularly the board thickness acceptance range, remain compatible with the existing PCB design.
