Your benefits

Very precise detection with no scanning distance drift in case of vibrations
PinPoint technology can replace laser photoelectric proximity sensors in some applications, eliminating the need for laser safety measures, and the service life of the PinPoint LED is double that of conventional laser diodes
Less downtime due to ASIC chip technology by SICK
Reliable in operation with ambient light, optical reflections, and when devices are mounted opposite one another
Reduces setup costs e.g. in case of format adjustment by IO-Link sensor communication interface
Highly stable housing due to offset fixing holes
For use at temperatures as low as 40 C
