Product Overview
The Optomax Industrial Series liquid level switches offer versatile detection for a wide range of liquid types, including oil and water-based fluids. Designed for industrial environments, these switches feature robust construction with a choice of Polysulfone or Trogamid housing materials and multiple thread options for mounting. They provide direct load drive capability and operate with industrial supply voltages.

Notes:
- Other sensor options available on request.
- Hex nut and O-ring sold separately.
- NPT version can be sealed with PTFE tape.
- Above +85C, Trogamid is suitable for water-based liquids. Oil-based liquids may cause deformation and must be tested for compatibility.
- Before use, check fluid compatibility with Polysulfone or Trogamid.
- Minimum load impedance should not exceed Vs/max output current.
- Shorting the output to Vs or 0V will result in irreparable damage.
