BERNSTEIN Series CP and CPS polyester enclosures
are produced from highgrade glass
fibre-reinforced polyester. Thanks to their
reduced surface resistance (Ro < 109 Ohm),
the black polyester enclosures meet the
requirements for Ex applications. Polyester
enclosures are therefore particularly suitable
for accepting and encapsulating electrical
and electronic components as well as
control components in harsh environments
or potentially explosive atmospheres (see
Page 14). All enclosures achieve protection
class IP66 in accordance with IEC529 (optionally
IP67).
Corresponding to their size, BERNSTEIN
polyester enclosures feature M4 or M6
mounting elements in the enclosure body.
These galvanised steel bushes are embedded
in a flange on the narrow sides of the
base and accept mounting plates, mounting
rails, pc boards etc.
The captive stainless steel cover screws
are retained by a self-latching element
integrated in the cover. The threaded
bushes for mounting the cover are also
made from stainless steel. The protection
class (on the standard enclosure) is ensured
by a factory-fitted seal. The polyester
enclosures are available as standard
in grey (RAL 7000, squirrel grey) or black
(RAL 9005, jet black) material.
