Industrial safety specialist,
Castell, has launched a 72-
page product catalogue for its
main product range of
trapped key interlocks, which
are typically used with
machine guarding and in the
switchgear industry. The
catalogue is designed to
facilitate understanding and
selection of products and
systems.

There are three factors to
consider when designing a
trapped key interlocking
system: the power source
being isolated; the number of
access points there are; and
the type of access required.

The layout of the catalogue
reflects this selection process,
enabling customers to choose
the right safety system or
products according to their
specific requirements.

In addition, an application
example is provided for each
product to clarify its
functions and uses.
