Industrial electromagnetic environment

*1. The Detector may not operate around the setting value of “0”. Adjust the sensitivity depending on the actual application.
*2. The insulation resistance and dielectric strength indicate values between power terminals and Electrode terminals,
      between power terminals and contact terminals, and between Electrode terminals and contact terminals. Refer to
      Safety Precautions on Data Sheet.
