✳️ Direct Projection Type Safety Light CurtainRPZ

Safety Light Curtain Possessing Both Safety and Functionality

This direct-projection safety light curtain for press machines has the highest-level safety based on a design compliant with international standards, advanced basic performance including enhanced noise resistance and is equipped with a series connection function and error display function in the event of a problem, making it suitable for a variety of work sites.

✳️ Features
  • Failsafe design for the highest level safety
    The highest level safety has been realized based on a failsafe design that utilizes mutual checking performed by two CPUs equipped in the receiver, and redundancy of the signal-processing circuit and output circuit.

    • Complies with international standard IEC61496-1/2 and North
      American standard UL61496-1/2.
    • Complies with China Standard GB4584-2007(some models)
  • Diverse line-up to cope with various operating environments
    Select the optimal safety light curtain according to the installation environment, type of press and work content.
  • Series connection function and error display function equipped
    Flexible installations matched to the operating environment and work content
  • Simple to adjust beams
    LED indicators equipped: Determine status of main unit with a single glance
  • Mutual interference prevention
    When multiple RPZ units are installed, a light interference avoidance algorithm (assigned according to the respective wavelengths of light sensors) can prevent mutual interference (up to three sets).
✳️ Safety Device Selection Criteria (Protective Range)
  • Mechanical press: (Die height + Stroke length) or more
  • Hydraulic press: (Full daylight range) or more
    * Note that the necessary protective range varies according to the installation conditions.
  • In the case that the top beam height at the time of installation is 1,400mm or less from the floor surface → (Die height + Stroke length + Insufficient length) or more
  • In the case that the top beam height at the time of installation is more than 1,700mm from the floor surface → (Die height + Stroke length – Excess length) or more
    * Lowest beam position is assumed to be the top surface of the bolster.
