Datalogic SR21

Datalogic's SR21 sensor measures only 2 mm. It is a photoelectric fork sensor for labeling and packaging. It offers high resolution, high speed and a very short response time in the positioning, application and precise printing of labels, even with very fast machinery and processes. It has a high switching frequency of 25 kHz. It has label detection (SR21-Ir) or printing mark in transparent films (SR21-RG). It also has four -wire NPN and PNP output, as well as IR or red/green light models. It is ideal for applications such as packaging and labeling machinery or printing and application systems.
