Today’s industrial plants operate under changing, often extreme conditions. So, safety sensors must not only have precision detection but must also be resilient. The safety sensors PSEN from Pilz are designed for use in environments with dust, vibration, cold, humidity and cleaning processes. Thanks to high protection types, robustness to shock and vibration and a durable design, they support constantly high plant availability. Robust sensor solutions include, for example, the safety light curtains PSENopt II, the safety locking device PSENslock 2 and the safe radar systems PSENradar. Each of these technologies is optimised for specific environments, from hygiene-critical areas to applications prone to dust and chipping, such as metal and woodworking.
