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.

Monitor liquid levels in your industrial tank with this float switch from Sensata Cynergy3. The floating component sits on the liquid surface and uses magnetic force to open or close the switch whenever levels go up or down. This makes it useful for preventing overflows when filling an industrial tank, or for knowing when liquid levels are low and the tank needs refilling. This is a vertical float switch that mounts to the top or bottom of the tank, so you don't need side access. Use this switch for applications such as water wells and boilers.

• Polyphenylene sulfide (PPS) body material protects the internal magnets from interference and damage
• Maximum current capacity of 1A for dependable use with low-voltage currents
• Wide operating temperature range of -10°C to +120°C for use in both cold and hot liquids
• Long cable length of 1m ensures a flexible connection

The switch has normally open (NO) or normally closed (NC) output options, giving you flexibility in the layout of your electrical circuit.
