SSt Sensing Limited OPTOMAX LLC700 Series Liquid Level Switch, Threaded Mount, Polytetrafluoroethylene,

SSt Sensing Limited LLC700D3SH OPTOMAX LLC700 Series liquid level switch is a precision-threaded mount sensor designed for accurate liquid detection in industrial and commercial fluid management applications. It features a polysulfone housing and polytetrafluoroethylene gasket, ensuring durability and chemical resistance across diverse environments.

With an operating temperature range from -25°C to 80°C and ability to withstand pressures up to 7 bar, this level switch supports reliable operation under demanding conditions. It has a maximum DC voltage rating of 15.4 V and maximum current of 2.5 mA, integrating electrical protections such as reverse polarity, electrostatic discharge (ESD), and transient over-voltage safeguards.

The device offers a push-pull output capable of sinking or sourcing up to 100 mA, allowing it to directly drive small loads without additional components. An optional fail-safe PWM output is available for applications requiring enhanced safety and control. Its compact threaded mount design enables installation in confined spaces, detecting even minimal liquid presence, making it ideal for leak detection and monitoring tasks.

Additional features include fast response time, repeatable switching points, and optional built-in output delay for environments where fluid movement or sloshing may cause intermittent switching. The robust construction permits use across a wide variety of fluids and chemicals in industrial, laboratory, HVAC, water treatment, and agricultural settings.

This liquid level switch supports internal and external mounting options, with versions available for extended temperature ranges and higher pressure ratings. The solid-state design eliminates moving parts, enhancing long-term reliability and reducing maintenance requirements.

Polysulfone housing and PTFE gasket ensure chemical resistance. Operating temperature from -25°C to 80°C suits varied environments. Electrical protections enhance durability and safe operation. Push-pull output enables direct load driving up to 100 mA.

Compact design allows installation in limited spaces and leak detection. Fast and repeatable switching ideal for precise fluid monitoring. Built-in delays prevent false switching caused by fluid sloshing. Solid-state for no mechanical wear and maintenance reduction.
