Anti-Water/Dust IP Technology

What is it?

To protect against damage from environmental factors, IP sealing offers resistance to water, dust, and humidity. This technology has been tested by Winmate, following standard product design testing procedures.

Various mechanical IP dust & water proof designs are available, as well as ruggedized industrial flat panel LCD displays. Ruggedized LCDs are designed specifically for high reliability, shock and vibration tolerance, survival of high temperatures, and corrosive environments. The combination of IP65 technology and ruggedization results in a product that is ideal for outdoor environments.

Table of IP Sealing Ratings

First Number (Protection against solid objects)	Definition	Second number (Protection against liquids)	Definition
	No protection		No protection
	Protected against solids objects over 50 mm (e.g. accidental touch by Hands)		Protected against vertically falling drops of water
	Protected against solids objects over 12 mm (e.g. fingers)		Protected against directsprays up to 15 degree from the vertical
	Protected against solids objects over 2.5 mm (e.g. tools and wires)		Protected against direct sprays up to 60 degree from the vertical
	Protected against solids objects over 1mm (e.g.tools, wires and small wires		Protected against sprays from all directions, limited ingress permitted
	Protected against dust,limited ingress (no harmful deposit)		Protected against low pressure jets if water from all directions,limited ingress permitted
	Totally protected against dust		Protected against strong jets of water e.g. for use on shipdecks — limited ingress permitted
			Protected against the effects of temporary immersion between 15 cm and 1m. Duration of test 30 minutes
			Protected against long periods of immersion under pressure

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 they are 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.

Table of NEMA Enclosure Ratings and Comparison to IP Code

NEMA Enclosure Rating	Description	IP Classification Code
1	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.	IP20
2	NEMA 2 — Same as NEMA 1 including protection against dripping and light splashing of liquids.	IP21
3	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.	IP54
3R	NEMA 3R — Same as NEMA 3 excluding protection against windblown dust.	IP24
3S	NEMA 3S — 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 in which the external mechanism(s) remain operable when ice laden.	IP54
4, 4X	NEMA 4 — 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, windblown dust, splashing water, and hose-directed water; and that will be undamaged by the external information of ice on the enclosure. NEMA 4X — Same as NEMA 4 including protection against corrosion.	IP56,IP65,IP66
5	NEMA 5 — Enclosures constructed for indoor 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; against settling airborne dust, lint, fibers, and to provide a degree of protection against dripping and light splashing of liquids.	IP52
6,6P	NEMA 6 — Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; toprovide a degree of protection against falling dirt; against hose-directed water and the entry of water during occasional temporary submersion at a limited depth; and that will be undamaged by the external formation of ice on the enclosure. NEMA 6P — Same as NEMA 6 including protection against the entry of water during prolonged submersion at a limited depth.	IP67
12, 12K	NE1V1A 12 — Enclosures constructed (without knockouts) for indoor 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; against circulating dust, lint, fibers, and against dripping and light splashing of liquids. NEMA 12K — Same as NEMA 12 including enclosures constructed with knockouts.	IP52
13	NEMA 13 — Enclosures constructed for indoor 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; against circulating dust, lint, fibers, and against the spraying, splashing, and seepage of water, oil, and non-corrosive coolants.	IP54

Technology/Function Diagrams

For each product, there are many different possibilities of sealing, the most typical of which, is front sealing. Other sealing options include the back side, the top side, the connectors, or a full seal. Type of sealing required is based on the application.

Standard testing procedures are applied to determine the degree of sealing required for each application.

IP6X Test — Test for protection against dust

IP6X Test — Test for protection against water

IP6X Test — Test for protection against water and dust

IP4X Test — Test for protection against dust

IP4X Test — Test for protection against water

The sealing concept of WAL Technology Inc. contains the following product sealings:

1. Glass or Touchscreen to front bezel
2. Internal dust sealing from LCD to the glass or touchscreen
3. Prepared sealing for mounting to the equipment

In addition to water and dust, other external factors such as cleaning solutions, salt water, UV from sunlight may all pose a threat. The right choice of sealing material is imperative and is a core competence of WAL Technology Inc.’s engineering and design capabilities.
