User Interface

A user interface is the control panel or other location where device status is communicated with an end-user. The more intuitive and seamless a user interface is, the safer the operation of that machine will be. There are many methods designers can use to enhance the user experience through the user interface.

User Interface Design

User interface (UI) design encompasses the look, feel and functionality of the device. From aesthetics to visual communication and controls, UI can really make or break a product. 

Using user-centric design (UCD) principles is a great way to develop, test and optimize an interface until the design is seamless, reliable, and intuitive.

UV-Resistant Lens

The sun’s UV rays can be damaging to equipment as well as our skin. 

UV-resistant lenses prevent PMIs from fading or discoloration in outdoor applications and can help extend their life and maintain accurate status indication.

V-0 Vertical Burn Flammability Rating

To attain the UL94V-0 flammability standard — the best in the industry — a series of burn tests are conducted on electronic components.The V-0 vertical burn flammability rating occurs when the burning stops within 10 seconds after two flame applications are applied to a test bar, resulting in no flaming drips.

V-1 Vertical Burn Flammability Rating

To attain the UL94-V0 flammability standard a series of burn tests are conducted. The V-1 rating is the second-highest score for this test.

The V-1 burn rating occurs when the burn stops within a minute after a flame is held to a test bar for two applications that are ten seconds each with no drips.

V-2 Vertical Burn Flammability Rating

The UL94-V0 flammability standard is the highest in the industry for safety, and V-2 is the lowest rating in this series.

The V-2 vertical burn rating occurs when burning stops after 60 seconds when two flame tests are conducted, each for 10 seconds. Flaming drips are allowed.  

Visual Communication

Visual communication is the combination of color, icons and light cadence within an HMI or control panel that helps the end-user maintain safe operation. 

There are several best practices designers can implement to achieve safer, more intuitive visual language. Learn how in our Status Light Guide.

Visual Language

In status indicator design, visual language is the collective experience of elements that work together to communicate with the operator or end-user

Several elements can be used to create the visual communication of a device, such as LED color, number of indicators used, light patterns, icons, and numbers.

Waterproof Light Pipe

As the name suggests, waterproof light pipes are those that have a high level of protection from liquids like sweat, blood, or rain. 

A component’s IP rating helps determine how well the product can withstand exposure, with ratings ranging from protection against water drops to full submersion up to 3.9 meters. 

Wide Flush Lens

A wide flush lens is a type of indicator lens that is even or “flush” with the HMI or control panel. It’s also wide in diameter to accommodate larger panels and easy viewing.

Wide Hi-Hat

A wide hi-hat is a type of indicator lens that extends well beyond the control panel rather than being flush with it that is also prominent in width for better viewing.

Wide Viewing Angle

Several factors can determine the viewing angle. The greater the viewing angle, the more light is shown and at different perspectives, but the overall intensity is decreased. 

A wide viewing angle, typically 160 degrees or higher, works best in devices where the LED will illuminate a large area or the light source is very close to the panel.
