Using programmablecontrollers, the signals can also be (pre-) processed.The devices have been developed for use in an environment that meets the IP20protection class criteria. Protection against finger injury and solid impurities up to12.5 mm diameter is assured; protection against water damage is not ensured.Unless otherwise specified, operation of the devices in wet and dustyenvironments is prohibited.
