| Housing | base: material PC (10 % GF), colour light grey (similar to RAL 7035), snap-on lid: material PC, transparent, cable gland PG 11 with strain relief |
| Membrane | silicone, LSR (Liquid Silicon Rubber, tempered at +200 °C, non-outgassing, LABS-free, no emission of varnish-adhesion inhibiting substances), long-term stability of switching points due to trapezoidal bead membranes |
| Humidity | < 90 % r. H., non-precipitating air |
| Mounting | by 4-hole base ring, plastic (included in the scope of delivery), recommended mounting position: vertical (pressure connections downward) – factory setting, horizontal (cap up/ down) |
| Protection class | II (according to EN 60 730) |
| Protection type | IP 54 with top cover (according to EN 60529) |
| Standards | CE conformity, low-voltage directive 2014/ 35/ EU |
