Ruggedized Design

A ruggedized computer is a computer specifically designed to operate reliably in harsh usage environments and conditions, such as strong vibrations, extreme temperatures and wet or dusty conditions. They are designed from inception for the type of rough use typified by these conditions, not only in the external housing but also in the internal components as well.

In general, ruggedized and hardened computers share the same design robustness and frequently these terms are interchangeable.

Wide Temperature Range

For many embedded applications, particularly those in military transportation, or where systems must be operated in harsh outdoor environments, a wide operating temperature range of -40 °C to +85 °C is typically expected, and this can be a challenging requirement to meet.

Fan – less Design

Usually the processor is the main heat producing part, but chipset and regulator parts also can generate significant amounts of heat. The processor and chipset should therefore be chosen to be as low power as possible, while still providing for the application processing requirements, and be verified to operate over the temperature range required.

The heat removal from the back surface of the die at the top of the processor package is a key part of the design. The heat spreader can also be used to touch most of the other main heat generating components.

Fans contain moving parts and are therefore vulnerable to wear and eventual failure. Although airflow from fans is very effective to remove heat from components, fanless designs are preferred because they have much higher reliability. Fanless systems are possible to achieve by factoring in careful thermal design considerations.

Water – Dust IP Proof

IP stands for International Protection Rating. IP codes classify and rate the degree of protection provided against the intrusion of solid objects, dust, accidental contact, and water in mechanical casing and with electrical enclosures.


Solid particle protection

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.


Object size protected against

Effective against



No protection against contact and ingress of objects


> 50mm

Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part


> 12.5mm

Fingers or similar objects


> 2.5mm

Tools, thick wires, etc.


> 1mm

Most wires, slender screws, large ants etc.


Dust protected

Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact


Dust tight

No ingress of dust; complete protection against contact

Liquid ingress protection

The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.


Object size protected against

Effective against


No Protection



Dripping water

Dripping water (vertically falling drops) shall have no harmful effect


Dripping water when tilted up to 15°

Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position


Spraying water

Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect


Splashing water

Water splashing against the enclosure from any direction shall have no harmful effect


Water jets

Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects


Powerful water jets

Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects


Immersion up to 1m

Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion)


Immersion beyond 1m

The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects

Wide Voltage

Wide Voltage could be completed as wide voltage solutions with acceptance of 9V~32V DV power input. The wide voltage design is not only for concerning of high voltage equipment, but also for those worries of different power input.

Particularly for electronic products used in public transportation and automotive, the voltage specification requires 5V~42V.

Anti – Vibration

Different applications have different anti-shock and anti-vibration requirements. Our products have different levels of shock and vibration protection standards. With the choice of different materials such as butyl rubber, ENR, high damping silicone and SBR, and appropriate structural design, they can meet vertical market standards. Proper packaging is also taken into account to prevent damage to the product due to impact and vibration during transportation.
