Understanding Types of Ruggedized Laptops and IP Ratings

A ruggedized laptop is a portable computing device that can withstand physical damages in harsh environments and conditions. Whether you're working in the construction business, manufacturing industry, or supply chain sector, every business requires rugged devices that have resistance to strong vibrations, extreme temperatures, dusty conditions, drops, water, and other rough situations. However, there are different types of rugged devices that offer different levels of ruggedness, durability and protection under a variety of working conditions.

1. Military-Grade Devices

They are designed to survive under the most hazardous and harshest conditions. They are labelled as indestructible. A common military-grade certification used in a rugged laptop is MIL-STD-810G. This certification means the device has undergone a series of 29 tests involving a range of environmental stresses.

2. Fully Rugged Devices

Fully rugged laptops are tough and designed to work properly in any environment, be it freezing temperatures, extreme heat, water spill, moisture, sand, or rough riding. They are more durable than semi-rugged devices but less ruggedized than military-grade ones. They are perfect for industrial applications with riskier situations.

3. Semi-Rugged Devices

Semi-rugged computers can handle some of the challenging environments, but not as much as fully-rugged or military-grade devices. Semi-rugged laptops are ideal for office use by utility workers, technicians, engineers, and other professionals whose jobs involve infrequent rough conditions.

Another factor that is used by device manufacturers to measure the ruggedness of devices is the Ingress Protection (IP) Rating. There are 6 levels of IP certification, starting from 0 to 6. 

IP Rating

Effective Against

0

No protection against solid objects

1

Protected against large surfaces

2

Protected against finger-sized objects

3

Protected against thick wires and objects

4

Protected against wires, screws, etc.

5

Some protection against dust and complete protection against contact

6

Complete protection against dust and contact

 There is a different IP chart for water resistance in rugged devices, starting from 0 to 9.

IP Rating

Effective Against

0

Nothing

1

Protected against 10 minutes of dripping water

2

Protected against 10 minutes of dripping water when tilted 15 degrees from the normal position

3

Protected against 5 minutes of spraying water at any angle up to 60 degrees from the vertical

4

Protected against 5 minutes of splashing water

5

Protected against water spraying from a 6.3-millimeter nozzle from any direction for at least 3 minutes

6

Protected against water spraying from a 12.5-millimeter nozzle from any direction at least 3 minutes

7

Protected against water up to 1 meter of submersion for 30 minutes

8

Protected against continuous immersion in water up to depth specified by the manufacturer

9

Protected against continuous high-pressure jets of water from any direction

If you’re interested in a fully rugged laptop or military-grade laptop but don’t know what level of IP protection or what type of device ruggedness is ideal for your business environment, then contact technology experts at Panasonic.

Rugged Tablet vs Commercial Tablet! Which One You Should Buy and Why?

Ruggedized tablets are crafted to work in extreme weather and harsh conditions and commercial tablets are designed as a self-service kiosk combining commercial-grade reliability with a powerful processor and an optional Power over Ethernet. Having defined both the tablets let us see how they differ from each other for better understanding so that you can make your choice according to your needs. • Operating system – Commercial tablets run on either of three operating systems – iOS, Android, or Windows whereas Android is the most preferred operating system in ruggedized tablets as it is easy to customize and deploy. • Weight – Rugged notebook or tablets are designed to withstand harsh environmental conditions and are tested for the military-gradeMIL-STD-810G standard. Because they have sturdier cases and are more resistant to shock, vibration, impact, and drop, they are heavier as compared to a commercial tablet. • Availability – Commercial tablets are available for sa...

An Insight on Different Types of Rugged Notebooks

When we talk about rugged laptops, tablets, and computers; being rugged means strong enough to withstand hazardous environments and unfavourable climatic conditions. However, not all rugged devices are same and might vary in their features and strength. You need to have a thorough understanding of the different rugged devices so that you can choose the best model that suits your needs. They are all tough and sturdy but they can’t withstand the same extremities or intensities. Here’s a look at the different types of rugged devices you can choose from: 1. Fully- rugged devices If your work environment consists of extremely difficult situations such as dangerous activities, severe natural conditions, or harsh weather, it is imperative to have a laptop that can function anywhere and anytime. The fully rugged laptops are designed from scratch where every component is weather proof and sealed. It protects the rugged notebook from moisture, salt, acid, sand, and other probable...
