These optical fiber sensors are specialized for uses such as the detection of leakage or surface level of chemicals and pure water used in semiconductor and LCD manufacturing processes, detection during wafer mapping, and detection of the dropping of an LED or other very small part.

Equipment becomes smaller and smaller, but there is probably room to install this approx. 10 mm-thick switch. The easily detachable switch head enables quick restart of equipment after a leak has occurred.

Features

• •Maintenance-free optical liquid leakage detection switch
  •Reliably detects liquids by ensuring sufficient gain between Light-ON and Dark-ON light levels. 
  •Sensitivity adjustment is not required. Can be used immediately after installation.

• •Acids or alkaline liquids, IPA (isopropyl alcohol), pure water, Fluorinert, Galden, etc.
  •Note: For explosion-proof applications, be sure to select a suitable fiber type.
  •Fluorinert and Galden are registered trademarks of 3M and Solvay Solexis respectively.

• •PFA protection for switch and cable
  •PVC bracket is available for acid/alkali detection, and PFA (with some SUS) for organic solvent detection.

• •Easy maintenance
  •the detector surface—a much easier process than with detection tape or a liquid-absorbing model.

• •Operation indicator
  •The operation status is indicated by the LED on the switch. It is green normally and orange if a problem occurs.
