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.
