Your Benefits

  • Small, compact sensor ideal for difficult installation conditions with limited space
  • Quick commissioning without medium calibration saves time and money
  • No moving mechanical parts reduce maintenance and eliminate the need to recalibrate, even after long periods of use.


Simple, compact, and rugged

The MHF15 is a compact optical level limit switch which is incredibly easy to commission. The sensor is based on SICK's energetic photoelectric proximity sensor technology, which has been tested and optimized over a number of decades. Thanks to this, the sensor design is simple, rugged, and reliable.. The use of high-quality materials such as stainless steel 1.4404 and polysulfone, combined with the housing in IP69K enclosure rating, provides reliability not only on the process side, but also in situations where there are adverse ambient conditions outside the tank. Fast, hassle-free commissioning does not require medium calibration, reducing both commissioning costs and maintenance. The optical technology makes the MHF15 particularly suitable for use with water-based media.
