Position detection:AMTROBOX EEx ia and AMTRONIC EEx ia
General
The intrinsically safe microswitches and inductive proximity detectors fitted in AMTROBOX EEx ia and AMTRONIC EEx ia are in
accordance with EN 60079--0 and EN 60079--11 standards relating to components installed in explosive environment.
They must be connected individually to an approved safety barrier. Situated in a safe area, these barriers allow the power supply of
the microswitches installed in hazardous area.
