Datasensor slot sensors of the SRF series are photoelectric devices characterized by an excellent precision thanks to the red LED emission which offers resolutions reaching 0.3mm or class II laser emission for resolutions down to 0.03mm. High precision and reading repeatability are obtained thanks to the laser emission combined with high switching frequency. Datalogic SRF series presents versions with 30, 50, 80 and 120mm slots guaranting best adaptation to the many different applications. Sensitivity adjustment is easily accomplished thanks to the trimmer positioned on the back side of the sensor. The range offers versions with PNP or NPN output, Light/Dark mode selection.
