Overview

The FD02FR16H-S is a low-profile, hexadecimal coded rotary DIP switch from NKK Switches designed for surface mount applications. It features a flush, screwdriver-actuated interface with 16 positions, providing a compact solution for binary or hexadecimal setting selection on a PCB. The switch is rated for logic-level switching up to 20VAC/DC at 0.4VA and utilizes gold-plated brass contacts for high reliability.

Why Choose This Part

The surface mount gull-wing lead design and 3.20mm height above the board enable high-density PCB layouts and automated assembly. Its gold-plated contacts ensure stable performance in low-energy logic circuits over a temperature range of -25C to +85C. The hexadecimal coding allows for 16 distinct states in a small 7.7mm square footprint, saving significant board space compared to toggle or slide switches.

Applications

Industrial Control Address Mapping
Setting unique hexadecimal identification addresses for modules on a shared communication bus.
Configuration Jumpers Replacement
Replacing traditional jumper pins with a rotary interface to select operating modes or hardware presets without loose parts.
Peripheral Mode Selection
Determining baud rates, protocol versions, or functional states in embedded systems during initialization.

Getting Started

When integrating this switch, ensure the PCB footprint accounts for the gull-wing leads and use a flat-blade screwdriver for actuation to prevent damage to the flush rotor. Consult the land pattern recommendations to ensure proper solder fillet formation during infrared or convection reflow soldering.
