What is this technology?
IP sealing is needed in various applications to make the products sealed against liquids, dust or humidity. Winmate is following the standard testing procedures to test the product design.
We provide various levels of mechanical IP dust & water resistant design and offer ruggedized industrial flat panel LCD displays. These Ruggedized LCD products are also designed for high reliability, shock and vibration tolerance, survival of high temperature, and corrosive environments. External materials like dust/ water can be very destructive to any type of equipment over time.

NEMA Enclosure
Rating and Comparison to IP
Code
NEMA (National Electrical Manufacturers Association) sets the industry standards in the USA for electrical equipment enclosures. In non-hazardous locations, there are several different NEMA ratings for specific enclosure types, their applications, and the environmental conditions they are designed to protect against when completely and properly installed.
The following provides an overview of the NEMA types. For complete definitions, descriptions, and test criteria, see the National Electrical Manufacturers Association (NEMA) Standards Publication No. 250. The European Standards are determined by the Institute of Petroleum and are sometimes referred to as Ingress Protection (IP) numbers. The standards are listed below.

NEMA 1 - Enclosures
constructed for indoor use to provide a degree
of protection to personnel against incidental
contact with the enclosed equipment and to
provide a degree of protection against falling
dirt.

NEMA 2 - Same as NEMA 1
including protection against dripping and light
splashing of liquids.

NEMA 3 - Enclosures
constructed for either indoor or outdoor use to
provide a degree of protection to personnel
against incidental contact with the enclosed
equipment; to provide a degree of protection
against falling dirt, rain, sleet, snow, and
windblown dust; and that will be undamaged by
the external formation of ice on the
enclosure.

against falling dirt, rain, sleet, snow, and
windblown dust; and in which the external
mechanism(s) remain operable when ice
laden.

Technology/
Function Diagrams
On a product there are many different possibilities of sealing. The most typical sealing is the front sealing. After mounting the product is sealed for dust and water (depend on the tested grade).
Besides the front side sealing, there are also other parts as the connectors, the back side, from the top and the full sealing, depending on the application.
We are doing related to the degree of the sealing the related tests with the products and check if there is any water, dust or dirt passing our sealing design.
1. IP6X Test----Test for protection against Dust
2. IPX6 Test ---- Test for protection against Water
3. IP65 Test---- Test for protection against Water&Dust
4. IP4X Test ---Test for protection against Dust
5. IPX4 Test--- Test for protection against Water
The Sealing concept of Winmate contains the following product sealings:
Glass or touchscreen to front bezel
Internal dust sealing from LCD to the glass or touchscreen
Prepared sealing for mounting to the equipment
Besides the sealing to water, also other liquids for cleaning, disinfection or saltwater are possible environments, witch influences the choice of the high tech sealing material and maybe the design concept how to seal.
Also the direct sunlight need to be considered in this choice, as UV-light can destroy the polymer structure of most sealing materials.
The right choice of the material is a core competence of Winmate’
s engineering and design capabilities.
