“KB” - “KM” SERIES LIMIT SWITCHES M 22 GB 14 10 03 1
“KB” - “KM” SERIES LIMIT SWITCHES FACTS The LIMIT SWITCH is an electromechanical device, which can interact with the ambient by sensing an external movement and transforming it into an electric signal that can then be handled by an appropriate control system. It can be used to detect the position of mobile equipment and for safety applications. M 22 GB 14 10 03 2
“KB” - “KM” SERIES LIMIT SWITCHES FACTS Three fundamental parts compose the LIMIT SWITCH: Head • Operating head Contact block • Body (housing or container) • Contact block M 22 GB 14 10 03 Body 3
“KB” - “KM” SERIES LIMIT SWITCHES LOVATO Electric has innovated the range of limit by designing the new K series with dimensions per EN 50047: • KB series with plastic body • KM series with metal body M 22 GB 14 10 03 4
