Rugged Handheld Computer (Windows)

The Unitech PA550 combines rugged industrial construction with smart phone functionality, making it ideally suited for sales automation and field service applications. Featuring a durable enclosure able to withstand 4-foot drops to concrete and shield against water and dust, the PA550 is designed to perform under harsh conditions. Despite its compact size, the PA550 is an extremely powerful mobile device. Driven by a high-speed 806MHz Marvell processor and Windows Mobile 6.5 operating system, the PA550 boasts full wireless connectivity, QWERTY keypad with programmable hot keys, and exceptional battery life for extended device runtime.

The PA550 features an auto-focus 5.0 megapixel camera allowing users to take photos and video for proof of service applications. With its integrated GPS, Bluetooth, WiFi and 3.5G WAN wireless connectivity, the PA550 provides positioning, tracking and tracing capabilities – anytime, anywhere.

The PA550 features a sunlight readable display for outdoor use. The Blanview® transmissive LCD requires minimal power consumption while providing a large viewing angle, and the Smart Light Sensor technology detects ambient light to automatically adjust screen brightness without manual configuration.

For global positioning applications, the PA550 utilizes the Ublox NEO-5Q Professional GPS module with KickStart® technology. Even under weak signaling environments, the GPS module provides accelerated startup, acquisition and tracking.
