Certified for hazardous locations, the EF550R Explosion-proof offers ATEX/IECEx Zone 2/22 certification for use in potentially explosive atmospheres. The EF550R Explosion-proof has been designed to deliver portable performance across a range of demanding industries such as Industrial manufacturing, Utilities and Oil and Gas.

The Largest-in-class Display

The largest-in-class 5.5-inch display provides more quality information to the device users and at the same time, it enhances working condition with the best-in-class outdoor readability for users to read the screen even in bright sunlight.

Ultimate Rugged & Durability

Through Bluebird TankSmith® technology and full rugged, EF550R Explosion-proof is designed for the enterprise with the highest-in-class drop spec of 8 ft. (2.4m) and sealing up to IP68 to provide the ultimate durability and usability allowing use in environments exposed to water, humidity, or dust.

Faster, Wider Network BUT Less Power

EF550R Explosion-proof has 2x2 Multiple-User Multiple Input Multiple Output (MU-MIMO) technology that makes possible for multiple devices communicate with access points simultaneously through pinpoint beamforming,
which leads to enhancement in Wi-Fi network speed, range, and capacity. And access point is the one who processes not the device, increasing device battery cycle time.

High-Capacity Smart Battery, Power for Hours

No need to worry about recharging while working!
EF550R Explosion-proof battery offers 14-hour power in serial use.

Safe as it is a hard-pack and stable battery operation with support of BOS™ PowerManager. Hot Swap mode is available without running any application, ensuring task continuity without turning off the device or an application.

Enterprise Mobile Device Software Ecosystem BOS™
