Environment
At the housing: –40 to +70 °C (–40 to +158 °F)
–40 to +85 °C (–40 to +185 °F)
Up to 2 000 m (6 600 ft) above sea level
DIN EN 60068-2-38/IEC 68-2-38: Test Z/AD
• IP65/67 NEMA type 4X enclosure (plastic housing cover)
• IP66/68/69 NEMA type 4X/6P enclosure (metal housing cover)
As per test Fh, EN 60068-2-64:2008: a(RMS) = 50 m/s², f = 5 to 2 000 Hz, t = 3 axes ×
2 h
As per test Ea, prEN 60068-2-27:2007: a = 300 m/s² = 30 g, 3 axes × 2 directions × 3
shocks × 18 ms
Resistant to typical cleaning agents from the outside, in accordance with Ecolab test.
Electromagnetic compatibility in accordance with all the relevant requirements of the
EN 61326 series. For details, refer to the Declaration of Conformity.
Only the requirements of IEC/EN 61131-9 are met if IO-Link communication is used.
If the device is installed in plastic structures, its function may be influenced by strong
electromagnetic fields. Emission requirements for class A equipment are met (only for use
in "industrial environments").

Process
–20 to +100 °C (–4 to +212 °F)
• For 1 h: +150 °C (+302 °F)
• M24 process adapter with EPDM process seal for 1 h: +130 °C (+266 °F)
–1 to +25 bar (–14.5 to +362.5 psi)
For reliable point level detection, the device can be adapted to the process conditions in
question.
