RSF73YNP, Sensata / Cynergy3 RSF70 Series Horizontal Nylon Float Switch, Float, NO/NC, 240V ac Max, 120V dc Max

Cynergy3 Horizontal Float Switches

Cynergy3 offers wide range of horizontal switches which are WRAS approved and have low-cost compact design. These horizontal float switches consist of a reed switch and a pivoted actuator magnet and can be used for N/O or N/C operation. The switch action can be reversed by mounting the float switch with the float able to move upwards away from the body instead of downwards.

WRAS approval explained

WRAS is the standard against waste, misuse, undue consumption or contamination of the water supply and must have an appropriate quality and standard.

What materials can you choose from?

• Nylon
• Polypropylene
• Polypropylene Sulfide (PPS)

Features and Benefits

• Operating temperature: -10 °C to +120 °C
• N/O or N/C Switch output
• Switch action may be reversed by rotating the switch through 180º
• Choice of gasket materials: Silicone, Nitrile, Viton or combination of Silicone & Nitrile
• Flying Lead
• M12 plug connection
• Internal & external fitting inside a tank
• UL recognised

Typical Applications

These Cynergy3 Horizontal Switches are most likely to be used in vending machines, commercial washing machines and evaporator units.

Note

Suitable for signal switching and for use with transistorised input/low power, suppressed coil miniature relays. Not suited for any inductive or inrush (e.g. filament lamps) loads.

Sensata Cynergy3 Horizontal Float Switch, NO/NC, 240V AC - RSF70 Series - RSF73YNP

This float switch from Sensata's Cynergy3 range is designed to monitor and respond to changing liquid levels in your tanks, containers or wells. It's designed for external mounting, so there's no need for access to the inside of the tank. Thanks to its wide operating temperature range of -20°C to +75°C, it's suitable for use with both hot and cold liquids. For enhanced versatility, you can reverse the switch action by mounting the switch so the float can move upward rather than downward. It's commonly used to activate pumps or alarms in waterworks, sewage systems and food processing machinery.

Features & Benefits

• M12 plug offers easy connection to circuitry and devices without the need for any additional tooling
• Nylon body for durability and corrosion resistance
• Nitrile gasket seal and back nut to help prevent leakage

How does this switch work?

The switch's actuator magnet causes electromagnetic fluctuations as it rises and falls with liquid levels. The corresponding sensor reacts to any changes in your tank's magnetic field and triggers the contacts to open or close.
