Cynergy3 RSF50 float switches are compact devices suitable for vending machines printing system and chemical dosing equipment, for example. RSF50 float switches are vertically mounted and feature a single switch.
There is a range of different material options available within the RSF50 series so you will be sure to find a suitable float switch for more commonly used liquids.
The direction of the switch can be reversed by firstly removing the float, inverting the switch and re-fitting it to the stem.

Within the series there are 5 ranges:
RSF53 (black) - Nylon
RSF54 (opaque) - Polypropylene (WRAS approved)
RSF56 (grey) - Polyphenylene Sulphide (PPS)
RSF57 (green) - Polyvinylidene Fluoride (PVDF)
RSF58 (white) - Polypropylene (UL approved)
Note - the different ranges feature other differences. Please refer to the Datasheet for more information on technical specifications.

What contact types are there?
The RSF50 float switches can be configured for N/O (Normally Open) or N/C (Normally Closed) operation.

What mounting thread does it have?
RSF50 float switches have either M12 or 1/8” NPT mounting thread. This is depicted by the last part of the part number. If it ends in “B” or “C”, it is an M12. If it ends in “1/8” it is 1/8” NPT.

Part numbers ending in '1/8' have a 1/8"NPT mounting thread
Part numbers ending in 'C' have an M12 mounting thread

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.

To prevent overfilling in your tanks, containers and other receptacles, monitor liquid levels with this float switch from Sensata Cynergy3. It's designed to be mounted vertically by fitting it through the top or bottom of the tank, making it ideal for containers where there's no side access. The float switch keeps the level of water in your tank between a must-close level of 15 mm and a must-open level of 26 mm. It's a reliable method to monitor and automatically control liquid levels using a pump.

• Operates in normally open (NO) and normally closed (NC) positions for versatile use
• Wide operating temperature range of -20°C to +100°C for use in demanding environments
• Suitable for use with most liquids, making it a reliable choice for industrial applications

This float switch is made from robust polypropylene to ensure long-lasting performance. It's resistant to chemicals and corrosion, making it safe for use with acids, alkalis, detergents and oils. This makes it a popular choice for printing systems, food processing equipment and vending machines.
