Sensata / Cynergy3 RSF30 Series Horizontal Nitrile Rubber (NBR) Float Switch, 1 m Cable, NO/NC, 300 V ac ac Max, 300 V

This float switch from Sensata Cynergy3 is a simple and highly reliable way to detect liquid levels in your system. For versatility, it can be used as an alarm or indicator, or to control a pump. It keeps the level of water in your tank between a must-close level of 23 mm and a must-open level of 52 mm to prevent overfilling or underfilling. You'll find switches like this one used for applications that need a repeatable signal to indicate when fluid has reached a pre-determined level.

• Polypropylene body and nitrile gasket for excellent resistance to heat and chemicals

A float switch is most commonly used in a tank to maintain the minimum and maximum liquid levels. When the fluid level reaches a minimum level, the switch signals a pump to operate and fill the tank. When the maximum liquid level is reached, the switch tells the pump to stop working. This means the fluid in the tank always stays within the pre-set range.
