RSF53V100MC, Sensata / Cynergy3 RSF50 Series Vertical Nylon Float Switch, Float, 1m Cable, NO/NC

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, 600mA - RSF50 Series - RSF53V100MC

This compact Sensata Cynergy3 float switch allows for close monitoring of liquid levels in applications with limited space. It offers both NO (normally open) and NC (normally closed) switch outputs for flexible use in liquid-level monitoring, high-alarm operations and overfill shutoffs. Thanks to its nylon construction, it's a durable choice that's resistant to corrosion and abrasion for use in harsh environments. The unit can be mounted vertically from the top or bottom of a tank's interior, so it's a good choice when you don't have access to the side of the tank. To ensure safe operation, keep the cable entry point dry by maintaining the mounting thread and cable entry above the liquid's highest level.

Features and Benefits

• Nitrile gasket material for a tight seal and resistance to corrosion
• Broad operating temperature range of -20°C to +75°C for use in challenging environments
• Cable length of 1m for flexible connections

How do you change the direction of the switch?

For flexible use, it's simple to reverse the switch's direction. All you need to do is remove the float from the tank and invert the switch. Re-fit it to the stem and re-install it in the tank.
