Photoelectric Series 3130 is 30 x 30 x 15 mm in size and has sensing range from 10 to 100 mm. Series offers temperature stability between -25 and 55˚ C, and repeat accuracy. Sensing range is independent of color or surface structure of object to be detected. Since intermediate digitalization has been dispensed with, resolution of the sensors is virtually unlimited. Analog sensors have bandwidth of 500 Hz, as well as voltage (0 to 5 V or 0 to 10 V) and a current output (1 to 5 mA or 4 to 20 mA) in the same device. Units are fully potted and equipped with glass windows.
