Aluminium enclosures
CA series
BERNSTEIN aluminium enclosures are
ideally suited to housing electrical,
electronic or pneumatic components.
Their high mechanical strength ensures
excellent protection against impact and all
sizes are sealed to IP 65, according to
IEC 529.
BERNSTEIN aluminium enclosures are fitted
with copper earthing screws (M4 or M6) in
both the base and lid, the surface below
the screws is unpainted allowing a good
earth connection to be made. The captive
lid screws are made of stainless steel and
are held in place by a lock integrated in the
lid. A gasket (for standard enclosures) is
factory-fitted, and ensures conformance
with the protection class. BERNSTEIN
