Nidec Copal RD Rotary Coded Switch

In modern electronic system design, maintaining accurate hardware addressing and parameter selection is critical for system integrity. The RD series addresses this by utilizing a high-precision rotary coded mechanism that translates mechanical rotation into stable binary (BCD) or hexadecimal outputs. The internal architecture is designed with high contact pressure, ensuring that selected settings remain secure even in environments prone to mechanical vibration or temperature fluctuations.

One of the key advantages of the Nidec Copal RD Rotary Coded Switch is its superior process compatibility. The switch is constructed from high-grade, heat-resistant resin, enabling it to withstand the thermal profiles of wave and manual soldering. Furthermore, its washable design allows manufacturers to remove flux residues effectively using standard cleaning systems without compromising the internal mechanics. With a mechanical life of 10,000 steps and a clear tactile response, the RD series provides professional-grade precision and exceptional durability for long-term hardware configuration.

Description

The Nidec Copal RD Rotary Coded Switch is a high-performance subminiature switching solution designed for reliable digital circuit configuration. Featuring a robust through-hole (DIP) mounting profile, this switch provides an intuitive and precise interface for setting binary or hexadecimal codes where board space is at a premium.

The Nidec Copal RD Series is a heavy-duty, PCB-mounted rotary coded switch known for its robust mechanical life and environmental sealing. Unlike the smaller SMD rotary DIP switches, the RD series typically features a larger footprint and a shaft for manual or tool-based adjustment.

The RD series is designed for reliability in industrial environments, featuring precious metal alloy contacts and an “O” ring seal.
