The SICK G20 Series Photoelectric Sensor has three base system configurations, including proximity sensor, though-beam sensor, and retro-reflective sensor. These models operate with a LED light source, using visible red or infrared light. Each unit is equipped with light/dark switching mode, with various switching output options including SPDT relay (electrically isolated), solid-state relay, and push-pull NPN/PNP outputs. Sensing ranges can start from 0m and go up to 120m (through-beam models only). An additional LED on the front of the unit, paired with rotary switches, expands this sensor's capabilities to include commissioning and operational checks. The G20 Series has optional time delay and adjustable sensitivity, making this product family highly adaptable for various applications.
