Programmable magnetic switches
ATEX magnetic switches are used to monitor the status of automation components in potentially explosion hazard atmospheres They detect the approach of a magnet without contact and above a certain switching value, they put out a digital signal. The switching value can be programmed.

Advantages – Your benefits

  • Programmable within no time
    due to non-contact adjustment of the switching points and hysteresis
  • Adjustable hysteresis
    for precise position monitoring – even at very low strokes
  • Suitable for narrow installation spaces
    due to wired teaching with TeachTool plug
  • Version with LED display
    for control of the switching position directly at the sensor
  • Version with standard plug connector
    for fast and easy exchangeability of the extension cable
  • Very flexible cable in PUR version
    for a long service life
  • C-slot sensor
    for space-saving, easy, and fast assembly on the product
  • Certification
    suitable for explosion-endangered areas

Options and special information

  • Sources of interference
    Sensors can be influenced by other magnetic fields in the immediate vicinity. Disturbing magnetic fields can be generated by motors, electric welders, permanent magnets or magnetized material (so-called soft magnets) such as hexagon socket wrenches, chips, etc.
  • Security for ATEX applications
    The sensor must be provided with a fuse that corresponds to the rated current. The breaking capacity of the fuse must correspond to the possible short circuit current of the supply source.
  • Connection cable for ATEX applications
    For MMS(K) 22-PI1...EX, the fixed connection cable should be connected in non-explosive areas or in a certified housing in compliance with an ignition protection type according to EN 60079-0 or in a certified housing according to EN 60079-31.
