Harsh environments. Dust. Dirt. Humidity. Extreme temperatures. These are all challenging conditions in which stable technology is required. Certain industries and areas of application place very specific requirements on the input systems that are used there. This is exactly where so-called “rugged devices” come into play: robust devices designed to withstand extreme environmental conditions and function reliably even under harsh conditions. But what exactly constitutes a rugged device and in which areas are they used?
What are rugged devices?
Rugged devices are specially developed electronic devices that are characterized by their high resistance to most environmental influences. They are protected against shock, water and dust and can withstand extreme temperatures and humidity. They are resistant to shocks and vibrations and are scratch and break-proof.
Such devices often meet high industrial and military standards, such as MIL-STD-810G or IP protection classes such as IP69K. Here are a few practical examples:
- Rugged tablets: high-performance tablets for industrial use
- Rugged laptops: special notebooks for use in field work, logistics or military operations
- Rugged HMIs: robust input systems with durable housings and reliable input technologies
Hoffmann + Krippner’s expertise in rugged devices: Application example rugged display solutions
H+K’s potential in component development for rugged devices is perfectly demonstrated by the special demonstrator for rugged display solutions. The features implemented there cover all the requirements needed for use under extreme conditions:
Impact resistance according to IK08
Protection class at least to IP67
Display heating for extreme low temperatures
Increased EMC protection
Light and temperature sensor in the bonding layer
Qualifiable according to environmental standards (MIL-STD-810G, DIN EN 50155, IEC 60068-2)
Control unit: Capacitive multi-touch with glove operation | modular buttons in a block of 6 connected via CAN (as buttons or rocker switches) | good switching feel and optimum button pressure point
Lighting: All buttons with individually dimmable lighting in RGB and separate white LED
Connection: HDMI input | power supply based on VG96916-5
With their decades of experience, our specialists have precisely the technological expertise needed to develop robust display solutions, for example:
In which industries are rugged devices used?
The areas of application for rugged devices and therefore also for the rugged display solutions from H+K are extremely diverse and extend across various industries:
Industry and construction: On construction sites, in construction vehicles and in production facilities, devices must be resistant to dust, falls and harsh conditions.
Logistics, transportation and rail technology: Mobile devices often have to withstand extreme temperatures and shocks in warehouses, when tracking goods and during transportation by road and rail.
Agriculture and agricultural technology: Rugged devices are often used in modern agriculture for GPS-supported machine control or data acquisition.
Peacekeeping and rescue services: Robust control panels and communication devices guarantee operational capability even in crisis situations.
Conclusion: Advantages and arguments for the use of rugged devices
Rugged devices have become indispensable in many areas. This is because they offer a reliable solution for the robust and safe use of technology in extreme environments when conventionally produced devices reach their limits. The numerous advantages for use in demanding working environments in particular speak for themselves:
- Durability: The robust design makes them more resistant than conventional appliances.
- Reliability: They work perfectly even under extreme conditions.
- Less downtime: Fewer repairs or component replacements mean reduced costs and downtime.
- Increased security: Many rugged devices offer special security features such as reinforced housings or encrypted communication.
