KeTop OP 300 Keyboard

Stationary operating devices with tactile short-stroke keys

Keyboard operation with tactile feedback

Operation panels of the OP 3x1 series are part of the high-performance KePlast control systems. Their primary focus is the operation of hydraulic standard injection molding machines. Insertable cards on the keyboard make it easy to adapt the keys to individual requirements, turning these panels into reliable operation devices for many other industrial uses as well.

The OP 3x1 keyboard operation panels come as monitor-only solutions with TFT color displays 7“, 8.4“, 10.4“ and 12.1“ without touchscreen functionality. They are operated using embossed short-stroke keys. The visualization is centralized and handled by a control CPU. The cost-efficient design combines robustness and industry-tested engineering with excellent value-for-money.
