Carlo Gavazzi's PD30CN series photoelectric sensors with PointSpot beam uses a visible red light narrow beam, which is meant to make detection more accurate and allow detection of smaller objects. The PointSpot beam is a safer alternative as it poses no concerns with damaging people’s vision and/or eyes.
Two versions exists: a background suppression version as well as a polarized retro-reflective version, both with a narrow red light PointSpot beam. The sensing distance is controlled by a potentiometer on the back of the housing. With this expansion of the PD30 Series, the PointSpot beam eliminates the halo light disturbance and increases detection reliability.
According to Carlo Gavazzi, the sensors are ideal for applications found on packaging, palletizers, material handling, plastics and machine tools.
