REQUEST A SAMPLE OR DOWNLOAD A 3D MODEL? WHY NOT DO BOTH?

Request a sample of your chosen electronic enclosure

DRAWINGS CONFIRM THE FIT, SAMPLES CONFIRM THE FEEL

Every design engineer knows the moment when a specification looks sound on screen and then feels different in the hand. Dimensions, wall thicknesses and cutout positions can all be verified from a drawing. What a drawing cannot tell you is how an enclosure balances once the PCB and battery are inside, how the finish feels, or whether the edges are comfortable after 20 minutes of use. That’s the gap that a sample closes, and it’s why we encourage engineers to request one before committing to the design.

WHAT A SAMPLE TELLS YOU THAT A SCREEN CAN’T

Handling a physical enclosure answers a set of questions that are surprisingly hard to settle any other way. You can judge the stiffness of the walls and the quality of the moulding. You can see how the finish holds up under real lighting. You can check that the parting lines and edges are as refined as you need them to be. You can test how the two halves close and whether the fit inspires confidence. You can also place your PCB, display or connectors against the real mounting features and see the relationships between them for real.

Some of these questions occur only once the part is in front of you, which is precisely the point. Finding out at this stage costs a conversation. Finding out after tooling or a production order costs rather more.

A sample is also easy to share. Passing an enclosure across a table to a colleague, a product manager or a customer gets honest replies quickly, and it tends to be better feedback than a PDF can prompt.

WHERE FEEL MATTERS MOST: HANDHELD AND WEARABLE DESIGNS

For a benchtop instrument, ergonomics is a refinement. For a handheld or wearable device it is crucial. The enclosure is the interface between your electronics and a human body, and users form a judgement about quality within seconds of picking it up or wearing it.

This is where our own ranges make the case better than any description. BODY-CASE wristwatch-style enclosures have a glossy finish that only really registers when you see it move in the light and feel how the case sits against the wrist. BLOB has curves that guide the hand towards the controls; you need to hold one to understand why the designers departed so radically from convention, and why the result works. SOFT-CASE offers tactile contours that suit a secure, comfortable grip, while SENSO-CASE is shaped for single-handed scanning.

In each instance the real test is the one a user will apply, which is whether it feels natural to hold and operate for the length of time the application demands. Handheld and wearable products are also where small differences in size, weight and curvature add up. A sample lets you judge those differences honestly before they are built into a design.

THE 3D MODEL AND THE SAMPLE WORK BEST TOGETHER

We would not suggest you treat the sample and the 3D model as alternatives. They answer different questions, and the strongest specifications use both. The 3D model, available to registered users in x_t, step and sat formats, lets you work in your own CAD environment. You can position the PCB, check connector and display alignment, test clearances around pillars and bosses, and iterate quickly without waiting for anything to arrive. And our 2D drawings are available in PDF, DWG and DXF should you need them. The model is where you establish that your electronics fit and where you plan any machining, such as cutouts for interfaces, displays and cable entries.

The sample is where you establish that the design works for the person using it. It validates the model against reality and brings out the human factors that CAD cannot represent. It also lets you test practical details, such as how a decor foil or printed finish might look on the actual surface, or how a lacquer colour transforms a standard housing into your ideal enclosure.

Some engineers begin with the model to narrow the shortlist, then request samples of the two or three most promising enclosures to make the final choice. Others handle a sample first to settle the form and feel, then download the model to finalise the internal layout.

Either order works, and requesting a sample while you are still working on the model often saves a design iteration. Once you are confident in the choice, our customisation can take it further; in-house services include CNC machining, printing, laser marking, special colours, EMC shielding and assembly of accessories.

SPECIFYING WITH CONFIDENCE

Specifying an enclosure is a series of decisions made with incomplete information, and the aim is to reduce the uncertainty as early as possible. A 3D model removes doubt about fit. A sample removes doubt about quality, feel and finish. Together they give you a far firmer basis for the decision – and for the conversation with your colleagues, your customer and us.

To request a sample, add the enclosures you’re considering to your basket (and then submit your request). While you’re browsing the products, you can also download 2D drawings and 3D models (once you have registered). If you would like a second opinion on which enclosure suits your electronics, our expert team is always glad to talk it through.
