No compromise on accuracy
24 April 2013
Complementing its established range, Carlo Gavazzi has launched the PD30CN family of miniature photoelectric sensors. This new cost effective solution is suited to applications where high accuracy of detection is critical.
The PD30CN includes the latest technology in background suppression, which improves accuracy of the detection of colours and has a sensing range of 200mm, diffuse reflective, retro-reflective, with or without polarisation and through beam sensors which are used to detect objects either by reflection or interruption of the emitted light beam.
The background suppression model uses active pixel sensor’s (APS) CMOS array of 64 x 1 sensor with each pixel representing a specific position. The biggest advantage of a CMOS sensor is that it is immune to the blooming effect where a light source has overloaded the sensitivity of the sensor, causing the sensor to bleed the light source onto other pixels.
