Technical datasheet for SST Sensing Optomax Industrial Series liquid level switches, detailing specifications, electrical interface, and ordering information.
The Optomax Industrial Series liquid level switches from SST Sensing are designed to detect a wide range of liquids, including oil and water based fluids. They offer high‑power industrial supply voltage and a direct‑load drive design, with optional housing materials such as Polysulfone or Trogamid®.
Key specifications include a supply voltage of 4.5 V DC‑15.4 V DC (or 8 V‑30 V DC), a 1 A output current, and operating temperature ranges from –25 °C to +80 °C (standard) or –40 °C to +125 °C (extended). The datasheet also provides wiring diagrams, housing dimensions, and ordering codes for various thread and output configurations.
