By utilizing the full digital communication method, the AX-350/650DH MKIII exchanges huge packets of block information between transmitter and receiver.

It realizes the simplified and highly accurate optical alignment and also maintains the high reliable performance even in severe outdoor environments.

Up to four sets of multiple beam installations are available. The detector features simplified optical alignment with an LED which can be checked for beam strength easily, highly accurate alignment with no need to use a voltmeter and no need for beam blocking plates. There is no crosstalk for advanced digital communication. AX-650DH MKIII provides reliable detection with ATPC in spite of environmental changes, up to four sets for multiple installations and IP65.
