The ABB 1SBV012842R1211 is a limit switch that comes with a lever R 26.5mm, rubber roller Ø50mm, and both NO and NC contacts. This component has a rated current of 10 amperes. It is designed to be used as a fail-safe device, controlling, protecting and/or signaling the movement of machinery in a wide range of applications, such as conveyor systems, paper mills, textile machines, elevators and so on. The switch body is made from corrosion-resistant zinc die-casting with a dust-protective enclosure. This switch also features a switch head with a thermoplastic cover, and a widened contact gap provides superior protection against electrical arc-fatigue and false trips due to vibration, shock, and temperature changes.
