IP69K proximity switch

Under certain environmental conditions the reliability of standard sensors cannot be guaranteed for long operational life. For example, if a standard proximity sensor is exposed to high-pressure water jets in a car wash system, water can forced into the sensor and create a potential cause for failure. For this reason Pepperl+Fuchs designed in new sensor features to reduce the effects of high pressure environments and ensure problem-free use in such applications. Design features of our proximity switches include a tighter construction fit of mechanical parts such as plastic caps and sensor housing, plasma cleaning of all surfaces to which sealant is applied and the pre-sealing of the coil system. This allows for characteristics to be achieved which are significantly above the test requirements for IP67/ IP68 ratings.
