    2015  SI- SERIES Magnetic Switches 2 
     
    DESCRIPTION: 
    The  magnetic  switches  and  inductors  used  for  motion ,  position, and  limit  detection  on  equipment  and  moving 
    systems  in  difficult  environments.        These  product s  are  used  in  industrial  environments  where  motion  and  position 
    detection  is  of  utmost  importance,  or  even  vital.  T hey  are  used  in  different  applications  in  rolling  mills  and  steel 
    mills such as opening and closing locks and gantry  cranes positioning.   These solutions offer contact-free  detection, 
    with no mechanical intermediary, and function witho ut any external power supply (no batteries, or main supply).  
      
    The  switch  mechanism  consists  of  two  changeover  con tacts  on  a  movable  plate,  which  are  operated  simultaneously 
    and controlled by permanent  magnets contained  withi n the  switch. The position of the  movable plate can be altered 
    by the influence of a magnet of the correct polarit y moving in the proximity of the switch.   Two type s of switch are 
    available, each with a different operating action d ependent on the control function required: 
      A
    UTOMATIC RESET -  Mechanical Analog Type with Roller Switch.  (RA): is operated by the approach of the 
    inductor and is only maintained as long as the indu ctor is within the operating zone. On leaving the proximity 
    of the switch the contacts will return to their ori ginal position. 
      T
    WO POSITION -  Mechanical Analog Type with Tumbler Switch.  (PS):  is operated by the movement of the 
    inductor while in the proximity of the switch, and  remain in that position until such time as they are operated 
    by  the  passage  of  the  inductor  in  the  opposite  dire ction.  Effectively  the  switch  is  memorizing  the  mov ement 
    produced by the inductor
    .
