          *1 IO-Link specification v.1.1/COM2 (38.4 kbps) is supported. (LR-ZH490CB : Only when PNP output is selected.) You can download a setup file from the KEYENCE website. If using the product in an environment in which downloading files over the internet is not possible, contact your nearest KEYENCE office.
          *2 Display readings can be used as a guide for the detecting distance. When the setting value is tuned, the readout shifts. When the value exceeds "-99", "-FF" is displayed.
          *3 Have passed resistance tests with cleaning agents from multiple manufactures.
          *4 When the response time is 10 ms
