Sensata / Cynergy3 RSF50 Series Vertical Polypropylene Float Switch, Float, 1m Cable, NO/NC, 240V ac Max, 120V dc Max

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.

Regulate liquid levels in your tank or sump with this Sensata Cynergy3 float switch. Changes in liquid level cause the float to move which brings the internal magnet into close proximity with the reed switch, activating an open or closed circuit. This compact and durable device is most commonly used to operate a pump, and typical applications include vending machines, printing systems and chemical-dosing equipment. It can be fitted to the top or bottom of your tank to suit your access needs.

• NO (normally open) or NC (normally closed) options for flexibility when designing your electrical circuit
• Wide operating temperature range of -20°C to +100°C for use in challenging environments
• 1m cable gives connection flexibility when installing
• Standard M12 mounting thread for universal connections

Expertly designed Sensata Cynergy3 float switches are manufactured in a variety of durable plastics. They also come with a choice of gasket materials to suit the most commonly used liquids. Conveniently, the action of all of the switches can be reversed by removing the float, inverting it, then refitting it to the stem.
