From the Inside: The Configurable Plastic Enclosures Revolution
Robert Cox, Vice President of Marketing
OKW Enclosures, Inc.
Plastic enclosures are undergoing a something of a revolution
that has the potential to transform the way in which electronics design engineers approach projects. Long gone are the days
when designers needed three different enclosures for wall
mounting, desktop and handheld applications. Now one configurable plastic
housing does it all.
Today’s ranges of configurable plastic
enclosures come with numerous base
units, wall brackets and ergonomic carrying options, enabling engineers to create
flexible products for an increasingly
demanding world. Today’s highly mobile
and design-conscious end users often
need data gathering and communications
devices that can be handheld, then perhaps cab-mounted in vehicles and finally
clipped into desk units for data download
and mains charging.
Meeting these ever-changing needs requires versatile enclosures that be configured and re-configured quickly, easily and
cost effectively as requirements evolve.
Engineers are turning to plastic enclosures that can be easily configured to
house membrane keypads, touch screen
displays plus charging/data download sockets, merely by clipping in different sections
They know that specifying configurable
plastic enclosures early in the design process not only makes for a better end product, it can significantly
cut manufacturing costs and shorten time to market.
In the past, design engineers often faced a dilemma, either they
could compromise and use a standard plastic enclosure or bite the
budget bullet and invest in their own custom enclosure. Now they
can get the best of both worlds by choosing configurable standard
plastic enclosures that can be tailored to their needs.
OKW’s Interface-Terminal range exemplifies the modern face of
configurable plastic enclosures with:
• Front Covers and Plates – For use with membrane keypads
and glass touch screens (a world first)
• Rear Plates – Including snap-in strips for versatile mounting
and lowered mounting pillars for extra space
• Handheld Options – Such as battery compartments and
charging points
• Desktop base units and wall mounting options.
But the journey that led OKW designers to Interface-Terminal
actually started 30 years ago. This has been quiet revolution that
first started back in the 1980s. Configurable plastic enclosures
took their first steps with OKW’s Vario-Box, a range of rugged
enclosures still in production today. Vario-Box was aimed initially
at mounting machinery controls to factory walls. At that time,
desk-mounting was not seen as a priority but the range has since
acquired carry handle bars that make the housing desk-friendly as
well as hand-portable.

Fast forward to the 1990’s and the focus had shifted from heavy
industry to the world of retail. Growing numbers of point of sale
applications needed attractive and consumer-friendly enclosures
that could be configured in any number of different ways. Allied
to the demand in retail was a growing market for facilities management and building access control equipment. It needed to be desk dockable, as
well as portable and wall mountable.
So design styles softened as the
emphasis switched from the factory
wall to the office wall and the desktop,
as exemplified by configurable plastic
enclosures ranges such as OKW’s DatecTerminal range with its sloping fronts and
wide range of lid options. Datec-Terminal
was the first plastic enclosure that could
directly accept a bar code reader or a
magnetic strip reader, putting it firmly in
the point of sale world, but it was also
used widely in light industry to house control equipment. Like Vario-Box, it is still in
production today.
Ten years on and configurable plastic
enclosures entered the 21st century with
OKW’s Art-Case, a step forward in both
functionality and aesthetics. As the name
suggests, Art-Case is as modern and attractive as it is versatile. Circles and gentle
curves are the hallmark of Art-Case that,
as well as wall, desk and handheld options,
offers ceiling mounts to accommodate
smoke or gas detectors and similar monitoring devices.
Art-Case offers four housing shapes – circular, lozenge-shaped,
square and rectangular that can then be configured with a
choice of:
• Domed and recessed tops
• Three angles of inclined cases
• Raised level and raised inclined cases
• Europlug connection and battery compartment.
Typical applications include transmitter and receiver units for
building services, detectors, medical and wellness devices, security
systems and peripherals.
Then in 2010 came the Interface-Terminal, the first ever configurable plastic enclosures to be compatible with touch screens.
Options include:
• Four Standard Versions – Fixed desktop, two part desktop
wall, mobile and mobile with station
• A Variety of Front Panel Styles – ABS cover and flat panel,
aluminum front panel and glass panel
• Battery compartment (5 by 1.5 v AA cells) and charging points
Units are mounted not with old-style fixed connections but
plug-in connectors to create a fast, easy and rational solution that
removes the need for fault-prone rewiring.
Development of the Interface-Terminal continues into 2013 with
the launch of an installation kit that allows the basic enclosures to
be flush mounted into a wall or control panel. The unit is mounted behind a bezel which means there are no visible screws. OKW
