The M18 tubular sensors of the SDS series, thanks to the background
suppression proximity optic system, precisely detect all objects inside the set
operating distance, independently from colour and rear fixed or moving objects.
The photoemitter is a red light LED that generates a visible circular spot; the receiver is a PSD (Position Sensitive Device) photoelement sensitive to the incident light's position.
A good vibration immunity and a low detection difference between lighter or darker objects are obtained as there are no moving parts for the optic triangulation.
The background suppression distance setting is precisely obtained by means of a multi-turn trimmer.
Normally open and normally closed outputs are both present with standard configuration.
