Degree of protection / housing / shielding design

The degree of protection given in the specifications indicates the suitability of
the device for various ambient conditions and also the protection it gives
people against potential risks when they are using it. The letters IP (Interna-
tional Protection), which are always present in the designation, are followed
by two digits. These indicate which degree of protection a housing offers
against contact or foreign bodies (first digit) and moisture (second digit).
All PMX modules and the basic device are designed with degree of protection
IP20 (as per DIN EN 60529).

New Greenline shielding design:
To improve electromagnetic interference protection, HBM has developed an
effective measure, the Greenline shielding design. The shield is connected to
the connector housing. Appropriate routing of the cable shield means that the
entire measuring chain is completely enclosed by a Faraday cage.
