Sensata/Cynergy 3 RSF50 Series Vertical Polyphenylene Sulfide Float Switch, Float, 1m Cable, NO/NC, 300V ac Max, 300V

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.

Choose this float switch from Sensata Cynergy3 for monitoring liquid levels in your tanks and other large vessels. It's designed for vertical mounting through a hole in the top or bottom of the inside of your tank. You can reverse the switch action by simply inverting it through 180°, making it a versatile component. It's suitable for applications such as vending machines, industrial printing systems and chemical dosing equipment.

• Wide operating temperature range of -10°C to +105°C for use in demanding environments
• Made of polyphenylene sulfide (PPS) material for chemical and abrasion resistance
• High maximum voltage rating of 300V for use in high-power applications
• Ample cable length of 1m for a flexible connection
• 1/8-inch NPT (National Pipe Thread) connection for a secure and simple attachment

This switch's actuator has an in-built magnet that causes changes in the magnetic field as it moves up and down with the water level. The contacts open and close when the switch's sensor responds to the change in magnetism.
