DescriptionATEX 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 benefitsProgrammable within no time
due to non-contact adjustment of the switching points and 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
for space-saving, easy, and fast assembly on the product
suitable for explosion-endangered areas
Options and special informationSources 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.
