RIKEN OPTECH CORPORATION r-PA Safety Light Curtain for Press Machine

Manufacturer: RIKEN OPTECH CORPORATION
Model: r-PA

Features

  • Self-diagnosis function at power-up
    At power-on, self-diagnosis is performed for about 1 second
    When no abnormality is found, the sensor immediately starts to operate normally.
  • Error-mode Monitor
    When an error arises, its cause is indicated with LED flashing patterns.
  • Mutual-interference Preventive Function
    When 2 sensors are so close to be mutual-interference, it’s prevented with making mutual-interference
    preventive connection.
  • Ambient-light Diagnosis Function
    With modulated light system, it’s mostly unaffected by ambient-light
    Also, it turns to be lock-out state when detecting external abnormal light.
  • External Diagnosis Function (Emitting Stop)
    Stops emitting of the emitter forcibly.
    It’s effective when pre-operation check of the safety system.
  • Both-Side Protection
    Control box (option) is selectable from one-side and both-side types.
    The both-side type enables to control 2 pairs of emitters and receivers simultaneously.
