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.

Rating system against intrusion.

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 Type Definition[1][2]
1 General-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.
2 Drip-tight. Similar to Type 1 but with addition of drip shields; used where condensation may be severe (as in cooling and laundry rooms).
3 Weather-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.
3R As 3, but omits protection against windblown dust.
3S As 3, but also operable when laden with ice.
3X, 3RX, 3SX X indicates additional corrosion protection; commonly used near salt water.
4 and 4X Watertight. Must exclude at least 65 GPM of water from a 1 inch 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.
5 Dust-tight. Provided with gaskets or equivalent to exclude dust; used in steel mills and cement plants.
6 and 6P Submersible. 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.
7 Certified 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.
8 Certified 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.
9 Certified 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.
10 MSHA. Meets the requirements of the Mine Safety and Health Administration, 30 CFR Part 18 (1978).
11 General-purpose. Protects against the corrosive effects of liquids and gases. Meets drip and corrosion-resistance tests.
12 and 12K General-purpose. Intended for indoor use, provides some protection against dust, falling dirt, and dripping non-corrosive liquids. Meets drip, dust, and rust resistance tests.
13 General-purpose. Primarily used to provide protection against dust, spraying of water and non-corrosive coolants. Meets oil exclusion and rust resistance design tests.

What is the IP rating important on an asset tracker?

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.

Solid Protection

 

IP Code Protection Object size
0 No protection N/A
1 Protection from contact with any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part, such as a finger Less than 50mm
2 Protection from fingers or similar objects Less than 12.5mm
3 Protection from tools, thick wires or similar objects Less than 2.5mm
4 Protection from most wires, screws or similar objects Less than 1mm
5 Partial protection from contact with harmful dust N/A
6 Protection from contact with harmful dust N/A

 

 

Moisture Protection

 

IP Code Protection Test duration Usage
0 No protection N/A N/A
1 Protection against vertically dripping water 10 mins Light rain
2 Protection against vertically dripping water when device is tilted at an angle up to 15 degrees 10 mins Light rain
3 Protection against direct sprays of water when device is tilted at an angle up to 60 degrees 5 mins Rain and spraying
4 Protection from sprays and splashing of water in all directions. 5 mins Rain, spraying and splashing
5 Protection from low-pressure water projected from a nozzle with a 6.3mm diameter opening in any direction 3 mins from a distance of 3 meters Rain, splashing and direct contact with most kitchen/bathroom faucets
6 Protection from water projected in powerful jets from a nozzle with a 12.5mm diameter opening in any direction 3 mins from a distance of 3 meters Rain, splashing, direct contact with kitchen/bathroom faucets, outdoor use in rough sea conditions
7 Protected from immersion in water with a depth of up to 1 meter (or 3.3 feet) for up to 30 mins 30 mins Rain, splashing and accidental submersion
8 Protected from immersion in water with a depth of more than 1 meter (manufacturer must specify exact depth) Varies Rain, splashing and accidental submersion

 

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.

 

Water Pressure

 

Water Ratings Protection Usage
1 ATM Withstands pressures equivalent to a depth of 10 meters (33 feet) Improved resistance to rain and splashes. No showering or swimming.
3 ATM Withstands pressures equivalent to a depth of 30 meters (98 feet) Rain, splashing, accidental submersion and showering. No swimming.
5 ATM Withstands pressures equivalent to a depth of 50 meters (164 feet) Rain, splashing, accidental submersion, showering, surface swimming, shallow snorkeling
10 ATM Withstands pressures equivalent to a depth of 100 meters (328 feet) Rain, splashing, accidental submersion, showering, swimming and snorkeling. No deep water scuba diving or high-speed water sports.
20 ATM Withstands pressures equivalent to a depth of 200 meters (656 feet) Rain, splashing, accidental submersion, showering, swimming, snorkeling, surface diving and water sports. No deep water diving.
