The FL 533 is an adjustable plunger limit switch manufactured by Pizzato. It features a NO + NC closure and has a length of 19-116mm. This switch is designed for industrial applications to trigger the switching of electrical components when a physical limit is reached or exceeded. It is made of die-cast aluminum, which ensures its resistance to most industrial environments. The adjustable plunger allows the height of the plunger to be adjusted, which can alter the distance the limit switch is triggered.
