Model DWS/DWM Door Monitoring Sensor


  • By detecting the opening and closing of the door, such as a food factory to prevent fraud and theft.
  • Open and close monitoring of the entrance door, such as drawers and safe.
  • Opening and closing and fault monitoring of the automatic door.
  • Monitoring of rack door open/close in the data center
  • Monitoring of door open/close on the slot machine


  • Small type for an easy installation even in shallow and narrow places.
  • Molded type that can be used safely even in places where water may splash.
  • In order to avoid malfunction in the commercially available magnet, it is equipped with many sensors.

International Standards

  • Our products do not have overseas safety regulations such as CE mark, UL standard, EN standard etc.

Usage Precautions

  • Always use a standard detector DWM-1 in the DWS-1, using the standard detector DWM-2 in the DWS-2.
    It does not operate a combination of DWM-1 to DWM-2 and DWS-2 to DWS-1.
    Please attach so as to be parallel to the DWS and DWM at the time of detection. 
  • In 0.59N · m (6kgf · cm) or less of torque, installed in two of the M3 screw.
