Tubular motor with electronic limit switch. S Size Ø 35 mm. Simple limit switch adjustment in manual, semi-automatic and automatic mode. Useful feedback from rolling shutter movement. Flawless movement even with friction: thanks to control of raising force, protects the shutter from damage during freezing conditions and recognises obstacles during lowering. This recognition is adjustable. Guarantees adequate protection against break-in when the rolling shutter is equipped with anti-intrusion springs. Time saving and simple electrical connections Thanks to the double insulation, no earth wire is needed. Low consumption in stand-by. Ideal for rolling shutters.
