Nidec Copal SA-5000 Rotary Coded Switch

In advanced electronic design, the ability to manually set hardware parameters with absolute certainty is critical. The SA-5000 series offers a sophisticated rotary coded mechanism that translates mechanical rotation into stable binary or hexadecimal outputs. This switch utilizes a high-pressure contact system, ensuring that your settings remain electronically secure even when subjected to mechanical vibrations or temperature fluctuations common in industrial environments.

A primary advantage of the Nidec Copal SA-5000 Rotary Coded Switch is its superior process compatibility. The housing is molded from high-grade, heat-resistant polyphenylene sulfide (PPS), specifically chosen to maintain structural integrity during intense reflow soldering profiles. Furthermore, the washable architecture enables manufacturers to remove flux residues using standard cleaning systems without risking damage to the internal mechanics. Whether you are configuring device IDs in networking hardware or setting operating modes in industrial automation, the SA-5000 series delivers professional precision in an ultra-compact subminiature footprint.

Description

The Nidec Copal SA-5000 Rotary Coded Switch is a high-reliability subminiature component engineered for precision digital circuit addressing and hardware configuration. Featuring a space-saving surface-mount (SMT) profile, this switch provides an accurate and stable interface for setting BCD or Hexadecimal codes in professional electronic systems.

The Nidec Copal SA-5000 (now officially under Nidec Components) is a versatile series of 11mm square rotary coded DIP switches. It is particularly known for its robustness and the unique option of having built-in resistors and diodes, which saves significant board space by eliminating the need for external pull-up or protection components.
