Sick india provides special magnetic cylinder sensors used to detect the position of pistons in pneumatic cylinders. They are attached directly to the piston through the housing wall, which could be made of aluminium, brass, or stainless steel. Sick magnetic cylinder sensors are fully electronic and are encapsulated in special housings, which can be attached simply to the pneumatic cylinders. Since they have no switching contacts or moving parts, the sensors are extremely reliable, even in applications involving severe vibration and shock stress. They are characterised by high sensitivity and switching accuracy, in addition to practical mounting technology for all current pneumatic cylinders. These sensors are available in many different models and versions.
