  • Your benefits

    Reliable detection of objects from PET bottles to transparent film.

    PinPoint technology for bright, small and precise light spot enabling fast and simple sensor alignment

    Precision switching characteristics and high standard of detection quality guaranteeing universal detection of objects

    Effective suppression of optical interference factors from the industrial environment

    Less downtime and robust metal housing resistant to high-pressure cleaner, cleaning agents and disinfectant, optionally available with Teflon coating

    User-friendly sensors, simple commissioning and installation plus simple sensor diagnosis due to easily visible status LEDs mean there is no need for specialist personnel or expensive training.

    Easily installed with SICK accessories
