• Differentiation between single and double holes
  One set of sensor is capable of differentiation between single and double holes, generating various types of output signals
• Simple optical axis alignment
  When light is fully received (nothing in the detection area between the transmitter and receiver), the AMP gain of the receiver is reduced to about 1/10 of the ordinary detection of punch holes. When the optical axis is aligned in this condition, the SAFETY lamp on the receiver is illuminated.
• Self check feature
  The transmitter is provided with light emission monitor circuit, which checks for any abnormality in light emission and outputs alarm signal accordingly. The receiver allows external checking of whether it is functioning normally.
  When light is fully received, the AMP gain of the receiver is automatically reduced to about 1/10. If the receiver detects full light reception in this condition, the SAFETY lamps on the receiver and controller are illuminated, indicating that the received light intensity level has a margin of more than tenfold.

Air purge unit or water cooling jacket can be optionally attached to the transmitter and receiver.

Air purge unit: model AP60ET (for transmitter), AP60ER (for receiver)
Water cooling jacket: model WJ60E (for transmitter/receiver)
