The areas of application include presses for metal working, powder metallurgy, printing and paperprocessing machines, croppers and similar, as well as machinery in the rubber, plastic and chemical industries.
Two-hand control panels are the preferred protection devices for use in setting-up work and single-stroke operations for feed and removal processes.

The machine safety is not limited to the use of safety sensors alone, but relies on the correct design of the safety interface. Two hand safety control will determine the overall safety to enviornment. A two-hand control requires constant, concurrent pressure by the operator to activate the machine. Monitoring of two-hand controllers requires a part-revolution clutch, brake, and a brake monitor if used on a power press. With this type of device the operator’s hands are required to be on control buttons, and at a safe distance from the danger area of the machine. A two hand control station circuit uses capacitive proximity switches to imitate the function of mechanical switches. A two hand control station is comprised of an isolation transformer, an enclosure, an electrically coupled isolation transformer, and a capacitive proximity switch. An adjustable two hand safety module includes both pneumatic models and electric models. Two hand safety modules are designed and manufactured to meet most industry specifications.
