This horizontal float switch from Sensata Cynergy3 monitors high and low liquid levels in a tank. It's designed for mounting on the outside of the tank, making it a good choice for situations where it's difficult to access the inside of the tank. It's made from a robust nylon material that's compatible with oils, diesel and other harsh liquids for use in demanding applications. You'll often find a float switch like this one used in vending machines and commercial washing machines.

• Ample cable length of 1m for a flexible electrical connection
• Wide operating temperature range of -20°C to +75°C for use in demanding applications
• PVC cable sheath to protect wiring from moisture and dust
• Switch action can be reversed by rotating it through 180° for versatility

The most important factors to consider when choosing a float switch are the type and flow rate of the fluid you're monitoring, as well as the electrical switching load.
