SM90-1100-SS Stainless Float Switch, SPDT, 1/8″ NPT, 8VA, UL Rated

Description

The Stainless SM90-1100-SS Float Switch is a rugged, high-performance liquid level sensor specifically engineered for industrial applications where durability and precision are critical. Constructed entirely from corrosion-resistant stainless steel, this float switch is built to withstand demanding environments, including exposure to harsh chemicals, oils, and water-based fluids.

Equipped with a Single-Pole Double-Throw (SPDT) reed switch, the SM90-1100-SS provides reliable and flexible level detection, making it suitable for both normally open (NO) and normally closed (NC) configurations—easily adjusted by inverting the float during installation. This versatility allows for integration into a wide range of control systems and tank designs.

Capable of operating at extreme conditions, the switch functions effectively in temperatures ranging from -40°F to 300°F (-40°C to 148.9°C) and can handle pressures up to 900 PSI, making it ideal for high-pressure and high-temperature environments such as hydraulic systems, chemical processing plants, food and beverage facilities, and marine or fuel storage tanks.

The SM90-1100-SS comes standard with 24-inch PVC-insulated lead wires, offering secure electrical connectivity and easy integration into control panels or monitoring systems. In addition to its robust mechanical and electrical performance, the switch is UL recognized, ensuring compliance with key safety and quality standards in North America.

Whether you’re designing a new system or retrofitting an existing one, the SM90-1100-SS provides a reliable, compact, and long-lasting solution for accurate liquid level monitoring. Its proven design and superior build quality make it a preferred choice for engineers and technicians who demand both performance and peace of mind.
