This is space-serving type motion sensor which consistsof a transducer to be mounted in the panel and a separated proximity switch to be mounted at the place where detection is conducted. It is possible to conduct speed control in the control room apart from the place where detection is conducted and to conduct collectively a integrated control by mounting side by side transducers from each place where detection is conducted.

Chute Switch is a safety switch vital to belt conveyors. It is used in order to stop  a belt conveyor instantly when a transported load clogs  a junction chute of the conveyor. This switch is so constructed that it should be mounted on the side wall of the junction chute by use of a square hole cut out in the wall. When the load clogs the junction , the swing plate of the chute  switch is pushed back with the pressure of accumulated load and then alarm signal to stop the belt conveyor is send.

Belt Sway Switch is a protective switch for detecting the sway or deviation of the belt conveyors and sends out an alarm signal and an emergency stop signal. This switch is used in material transport system for belt breakage prevention and ore-falling prevention due to belt sway.
