Sensata Cynergy3 Vertical Float Switch, 1m Cable Length, 600mA - RSF50 Series - RSF53Y100RC


Choose this sensitive vertical float switch from Sensata Cynergy3 to monitor liquid levels in your tanks. It's mounted either at the top or bottom of the tank from the inside, so it's a good choice for when there's no side access to a tank. This switch is made of a nylon material that's lightweight and waterproof, so it can withstand long-term exposure to liquids. Its nitrile gasket offers excellent abrasion resistance to stand up to wear and tear. You'll find this type of switch used in modern dishwater systems and water closets.

Features & Benefits


• Low current consumption rate of 600mA (milliamperes) for energy efficiency
• Cable length of 1m for flexible connections
• Wide operating temperature range of -20°C to +75°C for use in harsh environments

What precautions should I take while using this float switch?


It's important not to submerge the cable entry points of this float switch to avoid electrical hazards. If you're mounting the switch horizontally, you must fit it through the wall of the tank so the cable is outside. For vertical installations, the switch's mounting thread and cable entry points must be above the liquid level.
