It has a super compact size (φ33×47mm, 31g) and comes with an indicator light that makes the operating status easy to see. It operates without voltage, eliminating the need for a power source as a sensor. Silver contacts (standard) and gold contacts are available depending on the application. The micro switch uses a waterproof structure (IP67) that is resistant to harsh environments (excluding the terminal section). As options, a waterproof cover (transparent) and lead wire (300mm) are available. It is ideal as a sensor for various control devices. Additionally, we offer resin and rubber diaphragms that comply with food sanitation laws. *For more details, please contact us or download the catalog.
