Makrolon® 9415 Polycarbonate for Tablet & Display Unit Case Stud

Ready to withstand a rough and tumble world

Durable polycarbonate protects electronics in rugged applications

Products used in rugged environments - from industrial to outdoor to medical – must be tough and durable. This is the “real-world” situation InHand Electronics faced when developing its own Hydra-F6™ tablet and the display unit for the Praemittias Systems’ Wolfhound Cooperative Radio Direction Finding System® (Wolfhound).

For its rugged tablet and radio system, InHand Electronics required a commercially available material that was durable, moldable, resistant to chemicals and withstood impact testing. Makrolon® 9415 polycarbonate from Covestro, an easy-release, high-viscosity and flame-retardant grade, fit the bill. It is 10 percent glass-fiber reinforced and meets UL 94 V-0 rating at 1.5 mm and 5VA rating at 3.0 mm.

Standards compliance was important when developing the Hydra-F6™ tablet  – which offers the versatility and portability of a consumer tablet with the durability and long production life of a MIL-SPEC mobile device. With a size of 8.42 inches by 5.92 inches by 0.98 inches and weighing 1.5 pounds, the tablet meets challenging MIL-STD-810G, MIL-STD-461F and IP67 environmental requirements. The housing, molded from Makrolon® 9415 polycarbonate, borders the 7-inch WSVGA sunlight-readable display with touchscreen, brightness control and automatic display rotation.

InHand required a lightweight material (for portability) that was tough and satisfied MIL-SPECs to create a handheld display head for the Wolfhound device . The display head utilizes Makrolon® 9415 polycarbonate and provides a touch-screen LCD in a durable, lightweight package tethered to the main Wolfhound unit, enabling users to easily interact with the system while in environmentally harsh conditions.
