The Cynergy3 RSF66 single 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.
Single float switches are typically used in systems that feature PLC process control.

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.

Approvals:
WRAS, UL and NSF approved

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.

Looking for a simple way to maintain liquid levels in your tank or reservoir? Turn to this float switch from Sensata Cynergy3. Thanks to its polyphenylene sulphide (PPS) construction and nitrile gasket, it's resistant to heat, sunlight and abrasion, so it offers long-lasting performance in tough environments. These materials are also resistant to acids, alkalis and bleaches, so you can use the switch for a range of heavy-duty situations. The switch mounts vertically on the top of your fluid tank, so installation is straightforward. It's suitable for both high-level and low-level switching applications and is safe for use in food and beverage manufacture.

• Broad operating temperature range of -10°C to +85°C for use in a variety of demanding environments
• Suitable for use in programmable logic controller (PLC) process control systems for added versatility
• Cable length of 1 m for ease of connection

Electrical switching is achieved by using two normally closed (NC) switches. Each switch will break the connection when the float rises past it to maintain an appropriate fluid level.
