A worm gear and a helical toothed gear combined with one or more pairs of straight toothed gears are used for the transmission of the movement from the input shaft to the internal sensor.
Revolution ratios ranging from 1:15 to 1:150 result from the use of different combinations of gear wheels between the input shaft and the output shaft, which is connected to the cams operating the switches.
LimiteX rotary limit switches are built with a strong cast iron case and modular adaptor with feet of flange for the coupling of the units driving the switch.
Transmission and gear driving shafts are made of stainless steel to prevent oxidation and wear. The gear wheels and the driving bushes are made of self-lubricating techno-polymer material, suitably chosen to reduce the wear to a minimum and to maintain the accuracy of the couplings over time.
LimiteX rotary limit switches are the strong and reliable solution for any positioning control requirement in the Hazardous Location Areas.
