W 30 Photoelectric proximity switches: Clear signals even with low remission

Transcription

1 W 0 Photoelectric proximity switches Photoelectric proximity switches, BGS Photoelectric proximity switches, energetic W 0 Photoelectric proximity switches: Clear signals even with low remission In addition, the sensor offers a range of standard features. These include adjustable light- and darkswitching in the large terminal chamber, switching outputs that can be defined either for PNP, NPN or B configurations, and versions with optional time delay. FFixed scanning distances of 00, 00 and 0 mm requiring alignment once only; WT 0 sensors can detect even difficult objects. Thanks to their robust housing (with a high enclosure rating of IP ), these photoelectric proximity switches can also perform their tasks in unpleasant environments. A clear signal is generated for a machine control system even if only a small amount of light is reflected by the object. SENSICK CATALOGUE
