The sensors consist of a sensor head and an analysis module, and are laid out for use in very hot work environments. Together with unparalleled service life in hot surroundings, large switching distances assure maximum system availability. Easily interchangeable sensor heads with numerous standard cable lengths are additionally available as separate replacement parts.Switching distance can be quickly adjusted via a potentiometer within a temperature range of -60 to 450° C. Range: 25 mm; Speed: 200 Hz; Output: PNP; Circuit: NC+NO; Sensor head temperature range: -60...450 °C
