FD01/FD02 Rotary Switches

NKK's FD01 and FD02 series of switches combine compact design with high performance and reliability. Series FD01is perfect for high-density mounting in space-constrained environments. The switches have dimensions of 7.2 mm or 7.7 mm square and a height from 3.1 mm to 3.3 mm. This series also has through-hole terminals, with inch terminal grid spacing, making it versatile and easy to integrate into various applications. Series FD01’s internal structure has metal springs that enable smooth, crisp operation. These rotaries also boast advanced contact reliability with their gold-plated contacts, offering superior conductivity and resistance to corrosion.

Series FD02, while sharing the compact dimensions of series FD01, has the same low profile of 3.1 mm to 3.3 mm. This series is designed with surface-mount terminals that provide exceptional mechanical stability during the soldering process. This feature, combined with the ease of solder joint inspection, makes the series FD02 a reliable choice. They are encased in a heat-resistant resin, which maintains switch reliability through various types of soldering processes. Like series FD01, series FD02 also benefits from the incorporation of metal springs in its internal construction, ensuring that each activation is smooth and reliable.

Both the FD01 and FD02 are designed not only to meet the current demands of various industries but also to anticipate future needs. Whether it's for factory automation, robotics, or audio and communication equipment the FD01 and FD02 series offer a blend of compactness, durability, and high performance.

Features

• Compact dimensions of 7.2 mm (0.283”) or 7.7 mm (0.303”) square, with a height of 3.1 mm to 3.3 mm (0.122” to 0.130”), accommodates high-density mounting
• Internal construction incorporating metal springs promotes smooth, crisp operation
• Reaction force is evenly distributed by movable contact components, ensuring consistent connection. Advanced contact reliability is achieved through gold-plated contacts
• Heat-resistant resin used for series FD02 body maintains switch reliability through vapor phase and infrared convection reflow soldering
• Series FD01 features through-hold terminals with inch terminal grid spacing
• Surface-mount (gull-wing) terminals on series FD02 provide mechanical stability during soldering and simplified solder joint inspection
• Packaging in tape-reel for series FD02 meets EIA-481-D standard
• Remarkably precise coplanarity: all considered surfaces lying between two parallel planes are a maximum distance apart of 0.0039” (0.1 mm)
