WHY USER ACCESSIBILITY PLAYS SUCH A KEY ROLE

Aluminum enclosures for 19” rack electronics may look similar but their technical benefits can differ significantly. Specify too hastily and you could squander opportunities to enhance product quality, save budget and reduce maintenance time.

Standard 19” rack cases that can be easily customized are an excellent starting point for applications such as networking, communications, industrial control technology, sound and studio systems, and lab instrumentation. Standard rack cases are more cost-effective than bespoke housings.

But you risk limiting your design options if you specify the wrong standard case. User access is crucial in determining which model you’ll need. Ask yourself: “How will the users access the PCBs and other components when the case is in the rack?”

This is vital because it will help you to decide whether or not your rack case will need bezels – and thus ultimately determine:

  • how easily a rack case can be manufactured in custom sizes
  • the enclosure’s aesthetics
  • how easily color highlights can be added for branding.

Specify a rack case with a front bezel and you can easily remove the front plate. This enables you to access the electronics without having to pull the entire unit from the rack. Bezels also look more elegant. However, there are trade-offs: rack cases with bezels generally cost more – and they can limit your choice of custom sizes.

Instead, consider a 19” rack case that has no bezels. Specify one with a flat front panel that extends beyond the sides – one that is punched with standard obround holes for rack mounting. These enable easy adjustment when you’re installing the case in a rack.
