KeTop (KEBA Teach Operation Panel) is a mobile operating device concept for machines and systems that can be used as a teaching and programming panel for robots. The KeTop T50 boasts an improved ergonomic design and is designed for left or right hand use and thus enables a comfortable and fatigue-free operation. Through the double-walled construction and the shock-resistant display mount, the T50 can withstand a fall from a height of 1.5 m and was successfully tested for vibration, shock and continuous shock conditions. It is resistant to the effects of oils, greases, alcohols and salt acid condensates.
