With our passive sensor PHOTO 30 We offer an industrial sensor for detecting independent light sources: the sensor in a compact metal housing evaluates received light independently of its source and switches when its intensity exceeds a switching threshold that can be set using a potentiometer.

The passive sensor can be equipped for the visible or near infrared range and is available with transistor or relay output; There are also versions with analog output (3-8V), which enable easy measurement of the luminous intensity of light sources.

PHOTO 30 can also be used with fiber optics, which can be supplied in lengths of up to 20 m and with different protective jackets or end sleeves (see fiber optics). This means that the passive sensor can e.g. B. can be used to detect the presence of red-hot metals.
