Handheld Enclosures

Designed for remote control and mobile applications, handheld enclosures can fit comfortably in your hand or pocket. Lightweight, yet durable handheld instrument enclosures keep your electronics secure on the go. Molded from flame-retardant plastic, our ABS boxes and enclosures are available in a variety of sizes and styles for your handheld electronics. Some of our handheld project box series are enclosures with a battery compartment. Optional 20mm coin cell battery holders are also available for the key fob case styles. Polycase’s durable handheld enclosure styles are suitable for use as data loggers, controllers, network devices, medical equipment and so much more.

Choosing a handheld electronics enclosure for your device? Read below to understand which handheld enclosure may be the best choice for your project.

What’s the Best Handheld Enclosure for Your Application?

These are some factors to think about as you browse our selection of compact plastic cases: 

  • Material: We manufacture our handheld plastic enclosures from ABS plastic, an extremely popular material for handheld applications. It’s cost-effective, impact-resistant, easy to shape and machine, and has natural flame-retardant properties. 
  • Component Mounting: Many of Polycase’s handheld enclosures include features that make it easy to mount internal components, such as built-in PCB mounting bosses for easily adding a printed circuit board. 
  • Form Factor: Almost all handheld devices require a small enclosure with an ergonomic design. Polycase also offers additional form factor options, such as built-in buttons and keypads, that are especially useful for electronics applications like key fobs and remote controls.
  • Customization: Handheld electronics can require all kinds of custom cutouts for their various connectors, as well as digital printing for branding and user experience. Polycase offers both through our custom CNC machining and digital printing facilities.
