To protect against risks at shearing and crushing edges, safety sensitive edges are employed. Applications such as machine guards, lifting tables, theatre stages and many others are typical. Safety edges, when activated, will immediately switch off the power source. Prior to the launch of the Haake safety edge, either electrically operating devices to the N/O

In certain applications, the power-operated devices have, due to their inertia, long stopping times and thus also large stopping travels. Examples are big and heavy doors (hangar doors), automatically-guided vehicles (AGV), theatre stages etc. In these cases, the up to 150 mm high safety edges mentioned above will not be sufficient. Here so-called bumpers are

To protect persons against risks of this kind, pressure sensitive safety mats are employed. At devices such as machines, machining centres, presses, robot cells, high-shelf warehouses and many others, safety mats immediately switch off the power source, when the mat is stepped on. As long as the person stays on the mat, the machine cannot

Guard locking devices are for instance key-operated mechanical interlocks, also called trapped-key systems. They are based on the easy-to-understand premise that a key cannot be in two places at the same time – it can for instance be inserted in a switch OR be used for opening a guard. Another safety-relevant feature is that a

Valve interlocks are used everywhere where a sequence of valves helps protect personnel and machinery. These are mainly: offshore applications, chemical plants and refineries, or the gas industry as well as electricity and water suppliers. Valves have a very important safety function in many industrial processes. An operating error at a valve can have dramatic
