E2EH

Features

Heat and detergent resistant inductive sensor in cylindrical stainless steel housing

The heat and detergent resistant inductive sensors provide reliable metal object or machine part detection in demanding environments such as food processing.

  • Temperature resistant up to 120°C
  • SUS316L housing with heat resistant plastic sensing face
  • IP69k for highest water resistance
  • ECOLAB tested and certified detergent resistance

For stainless steel photoelectric sensors see E3ZM and for stainless steel safety non-contact door switches see F3S-TGR-N_C.

Environmental resistance

Chemical resistance

Issue: Detergents and chemicals used for cleaning or during the manufacturing process may severely damage (corode) the housings or sensing face of sensors. But apart from these consciously used chemicals, accidentally applied liquids (soft drinks with low pH values or sweat) can unintentionally damage the sensors.
Solutions
* Market standard: basic splash water protection for dry and protected machine environment.
** Tested enhanced high pressure water and saltwater spray protection with our E2A for open factory environment with occasional touching (sweat), cleaning or accidental liquid contact. The optional stainless steel housings may provide additional protection.
*** High and highest chemical resistance with our E2EH and E2FQ for frequent cleaning or intense and continuous chemical liquid contact.

Extreme temperatures

Issue: Continuously high or low temperatures exceeding the rated specifications quickly damage standard sensors. Suitable materials and/or product design are required for these applications.
Solutions:
* Market standard: normal ambient temperatures for operation and storage for standard factory environments.
** Specified extended operating temperature range down to -40°C with our E2A for machine operation in lower temperatures.
*** High temperature resistance up to 200°C with our E2EH and E2C for applications with high continuous temperatures.
