p>The ts-tl Series limit switches are designed and manufactured according to European standards EN 50041 for dimensions. The insulated housing of the limit switch is made of self-extinguishing thermoplastic giving excellent mechanical stability and is suitable, as a result, for assembly on machinery or installations in the general-purpose industrial field as well as Saline environments (for example close by the sea). the housing sturdiness allows mounting of limit switches in heavy duty applications.
