The TC51/56 industrial handheld computer keeps working reliably even after having been submerged in water, dropped onto concrete or when used in dusty environments. The unibody design provides effective impact-protection for its sophisticated electronics. The 5” touchscreen enables use with or without gloves, with a stylus and even in wet conditions. Unique dedicated keys can be created on either side of the display for one-touch access to the most frequently used device features.
