RSF66A50A150, Sensata / Cynergy3 Sensata / Cynergy 3 RSF66 Series Vertical Polyphenylene Sulfide Float Switch, Float, 1m Cable, Direct Load, 240V ac

Cynergy3 RSF66 Double Float Switches

The Cynergy3 RSF66 dual switch point series are float switches for high and low level switching. The RSF66 float switches are made using Polyphenylene Sulphide (PPS) in grey, which is ideal for a wide range of different liquids. This makes the RSF66 range versatile for different applications.
Dual float switches can be used to control filling or emptying tanks with electromechanical relays.

What length cable do they come with?
The RSF66 series comes with a 1m standard cable length with flying lead. It is a four core PVC cable.

What temperature can they withstand?
-10°C to +85°C / +14°F to +185°F

What is their power capacity?
RSF66 float switches have a power capacity of 25VA.

Warning

The Cable entry point must NOT under any circumstances be submerged:
– On the Horizontal switches they must be fitted through the wall of a tank so that the cable is on the outside.
– On the vertical type the mounting thread and cable entry must be above the highest level of the liquid.

Sensata Cynergy3 Vertical Float Switch, 2NO, 1m - RSF66 Series - RSF66A50A150

Choose this Sensata Cynergy3 dual float switch to keep your system's liquid levels within pre-set high and low limits. You can use it to control the emptying of tanks via electromechanical relays. The switch is made from durable and robust PPS (polyphenylene sulphide) which is compatible with a wide range of liquids, including inorganic and organic chemicals, oils and water. The device comes supplied with a four-core PVC cable, and you can mount it vertically on the top or bottom of your tank, so it's ideal for use when there's no side access.

Features & Benefits

• Wide operating temperature range of -10°C to +85°C for use in challenging environments
• 1m standard cable length with flying lead for flexibility
• Nitrile rubber gasket for resistance to corrosion and abrasion

How do I know when liquid levels are too high or low?

This device has an internal magnet that'll move in relation to the reed switch as liquid levels change. When the liquid reaches a specified level, the magnet will trigger the switch, which can then activate an alarm.
