Education is Key

GPS Vehicle & Asset Tracking Educational Webinar

Many fleet owners understand there is value in GPS vehicle and asset tracking technology but they don’t know where to begin or understand the overall technology. By not knowing what to ask or look for a fleet manager is subject to a sales person’s perspective, option, guidance or twist on a solution to stated fleet problems.

We’ve all heard education is power but it also money. If you are not educated and make a bad in investment, it will cost you or your company money. As in most industries and situations, there may be 3-4 ways to resolve an issue with a technology solution. In every industry there is low end, low-cost solutions all the way to expensive and complete solutions. Knowing what you need, understanding the technology and being clear on a process will ensure you get the right solution for the lowest investment.

NEMA Enclosure Rating Explained

NEMA is an organization that has developed an international standard for rating an enclosures resistance to various elements. Elements such as humans, moisture, debris, fire, temperature, pressure and other elements all determine an enclosures NEMA rating.

Understanding the NEMA rating can save you money in two ways. First, you don’t buy an enclosure with a NEMA rating well above what is needed. The “tougher” the enclosure or the higher the NEMA rating, the more expensive the enclosure. Second, you won’t under buy an the enclosure and lose what you are trying to protect in the enclosure.

For applications related to GPS vehicle tracking a NEMA enclosure from a big box store might be all you need and many are available in the electrical section for under $20.

NEMA TypeDefinition[1][2]
1General-purpose. Protects against dust, light, and indirect splashing but is not dust-tight; primarily prevents contact with live parts; used indoors and under normal atmospheric conditions.
2Drip-tight. Similar to Type 1 but with addition of drip shields; used where condensation may be severe (as in cooling and laundry rooms).
3Weather-resistant. Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. Used outdoors on ship docks, in construction work, and in tunnels and subways.
3RAs 3, but omits protection against windblown dust.
3SAs 3, but also operable when laden with ice.
3X, 3RX, 3SXX indicates additional corrosion protection; commonly used near salt water.
4 and 4XWatertight. Must exclude at least 65 GPM of water from a 1 in nozzle delivered from a distance not less than 10 ft for 5 min. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X (as 4X) indicates additional corrosion resistance.
5Dust-tight. Provided with gaskets or equivalent to exclude dust; used in steel mills and cement plants.
6 and 6PSubmersible. Design depends on specified conditions of pressure and time; submersible in water or oil; used in quarries, mines, and manholes. 6 is temporarily submersible, 6P withstands occasional prolonged submersion. Neither are intended for continuous submersion.
7Certified and labelled for use in areas with specific hazardous conditions: for indoor use in Class I, Groups A, B, C, and D environments as defined in NFPA standards such as the NEC.
8Certified and labeled for use in areas with specific hazardous conditions: for indoor and outdoor use in locations classified as Class I, Groups A, B, C, and D as defined in NFPA standards such as the NFPA 70.
9Certified and labelled for use in areas with specific hazardous conditions: for indoor and outdoor use in locations classified as Class II, Groups E, F, or G as defined in NFPA standards such as the NEC.
10MSHA. Meets the requirements of the Mine Safety and Health Administration, 30 CFR Part 18 (1978).
11General-purpose. Protects against the corrosive effects of liquids and gases. Meets drip and corrosion-resistance tests.
12 and 12KGeneral-purpose. Intended for indoor use, provides some protection against dust, falling dirt, and dripping non-corrosive liquids. Meets drip, dust, and rust resistance tests.
13General-purpose. Primarily used to provide protection against dust, spraying of water and non-corrosive coolants. Meets oil exclusion and rust resistance design tests.

Debris and Moisture Resistant

IP Rating System

The IP rating, or Ingress Protection Rating, is a “system for classifying the degrees of protection provided by the enclosures of electrical equipment, establish by the International Electrotechnical Commission (IEC). The IP code consists of two numbers, the first representing debris intrusion and the second representing moisture intrusion. The higher the number the more resistant the component is to intrusion. The IP does not include hypens but simply IP##. When an IP rating replaces a number with an X, the component has not been tested against that type of intrusion.

Waterproof

The term waterproof is a misnomer in the world of electronics. Nothing is waterproof but resistant to water pressure. All electronics can leak if enough pressure is applied under the right conditions. In general, electronics may be weatherproof or weather resistant which represent fall less invasive pressures.

As a rule of thumb, weatherproof GPS trackers should not be pressure washed at less than 3′ in order to maintain moisture integrity.
