The advanced air-purge technology provides the ultimate,
excellent anti-environmental performance.

This air-purge system dramatically increases the resistance to environment by supplying air to the sensor body to raise the inner pressure and preventing foreign objects from invading from outside. It exhibits strong performance in severe environments where liquids such as permeable oil, coolant liquids and cutting fluids spill over the detector.

※1 The value in the specifications is with an ambient temperature of 20°C.
※2 This value varies depending on the supplied air pressure.It also depends on the assembling accuracy of the product and wear of the sealing material (O-ring).
※3 This applies only when the air tube is connected and the sealing part is not degraded or damaged.
※4 An angle-type connector cable cannot be used.
◎ This type is not fitted with rubber bellows.
