RSF53Y100JC, Sensata / Cynergy3 RSF50 Series Vertical Nylon Float Switch, Float, 1m Cable, NO/NC, 240V ac Max, 120V dc Max

Cynergy3 RSF50 Series Float Switches

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.

Note

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

Warning

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.

Supplied with

epoxy sealed leadouts

Sensata Cynergy3 Vertical Float Switch, NO/NC, 1 m - RSF50 Series - RSF53Y100JC

Choose this compact float switch from Sensata when you need to precisely monitor liquid levels. It's a vertical switch, so you can mount it on the top or at the bottom of a container, making it an ideal solution when there's no side access to a tank.
It has NO (normally open) or NC (normally closed) options for flexibility in the layout of your electrical circuit. As this component is made from chemical-resistant nylon, you can use it with a wide range of substances, including oils, organic chemicals and printing inks.

Features and Benefits

• Nitrile rubber gasket for resistance to corrosion and abrasion
• Supplied with epoxy-sealed lead-outs for easy connection
• Wide operating temperature range of -20°C to +75°C for use in demanding environments
• 1 m cable for flexible connection
• Standard M12 mounting thread

How does this switch open and close?

A vertical float switch like this one has a magnet mounted inside the float, along with a reed switch in its body. The float fits around the stem and rises and falls with the level of the liquid. When the float nears the reed switch, the magnetic force causes the switch to open or close.
