1 NPA Pendant control station Product description The NPA pendant station is a control device for all industrial machinery. It operates as an auxiliary controller of electrical motors through a power interface, such as a contactor or PLC. Designed for heavy duty, NPA is aimed specifically for the industrial market. Both thermoplastic rectangular buttons and round disks are available, the latter mounted on rubber pushbuttons to guarantee protection against dust which may cause the pushbuttons to stick when the equipment is used under particular environmental conditions. Buttons and discs comprise of a moulded two-colour arrangement offering a combination of clear reading of symbols and text with maximum wear resistance. Materials and components are wear resistant and protect the equipment against water and dust. The pendant station can be customised with labels and colours according to the customer s requirements. By turning the cable sleeve on the central part axis, the pendant station is kept at an angle of inclination of 20 which allows the best view of all control elements, allowing the operator to work in a natural and non-tiring position. One, two or three speed switches are available. The emergency stop mushroom pushbutton complies with the EN 418 standard and is equipped with positive opening NC switches.
