Detection of position is ensured by a system of independently adjustable cams which actuate the electrical contact are usually used for applications where it is either impossible or impractical to mount standard type position sensors that are actuated directly by the moving applications:b position control of moving parts of hoisting or materials handling equipment (winches, travelling cranes, gantries, cranes, rotary excavators, etc.)

4 B liquid level control in pumping systems. Description 1 Input drive shaft2 Reduction gear3 Cams4 Contact blocks5 Potentiometer (option) OperationThe input drive shaft, which is coupled to the machine part being controlled, is normally fi tted on the right-hand side. This transmits the movement by means of a worm Screw and reduction gear to a set of 4 or 6 independent cams which, in turn, operate the contact choice of 3 cam types (20 , 50 and 80 ) enables a wide range of cam arrangements to be cams are easily accessible and individual adjustment of the cams is a simple operation, without risk of affecting the setting of adjacent an option, a potentiometer can be fi tted in order to provide an analogue limit switchesStandard duty, XRBAE nvironmentConformity to standardsIEC/EN 60947-5-1 Protective treatmentStandard version TC Special version TH on requestAmbient air temperatureFor storage C- + 70 For operation C- + 70 Shock resistance80 gn (11 ms)
