The proximity switch 490 with ATEX does not require contact and is triggered by a magnetic field or an Fe object. The device does not require a continuous air supply. A further advantage of the proximity switch is its compact dimensions.
The ATEX version of pneumatic proximity switch 490 is certified for use in potentially explosive atmospheres where there is a risk of gas or dust explosion, zones 1 and 21 as well as for Mining (category M2).
