VERTICAL
LIQUID LEVEL SWITCHES
VS Series
High- or low-level switching
N.O./N.C. SPST or SPDT outputs
Mounted on the top/bottom wall of a tank
Certified reed switch (UL component listed)
Many different configurations available
The VS series of point liquid level switches demonstrates a high
degree of reliability due to the use of non-reactive wetted components
and a unique reed switch designed specifically for level sensing
applications. The sensor utilizes a moving float with an embedded
magnet to activate a reed switch located in the sensor body. As the
liquid level raises the float, it moves into close proximity to the reed
switch and actuates it to give an open contact or closed contact
switch indication.
Features
Voltage rating up to 250VAC
Current rating up to 1.0 amp
Compact design and low profile
Optional cable lengths
Includes mounting hardware
The reliability of this sensor results from a very simple operating
principle, a single moving part, media compatible wetted materials,
and a unique reed switch design that has a UL recognized component
certification.
Applications
Water and fuel storage tanks
Full and/or empty detection
Pump on/off controls
The sensor mounts into the top or bottom wall of a liquid storage tank
using either a 1/2” NPT or M16 x 2.0 threaded fitting. The M16 mount
is available in either an internal or external configuration. The output
is a simple N.O. or N.C. SPST, or SPDT reed switch that utilizes
Ruthenium contact points for reliability. Changing from a N.O. output
to a N.C. output is done by removing the float and reattaching it in an
inverted orientation. This change can be done in the field. Electrical
outputs are a single pair or three wires with PVC insulation and
optional lengths of 0.5 m or 2.0 m.

Application Information
The versatile design of the VCS series level sensor provides four different mounting and operating
modes. The sensor can mount at either the top or bottom of a liquid storage tank. In either position,
the float can be oriented to provide a N.O. or N.C. contact. Because the magnet is positioned at one
end of the float, it can be removed from the body, turned upside down, and reinstalled to provide any of
the four configurations shown below.
To remove and re-orient the float, gently squeeze the retainer clips at the end of the sensor and slide
the float off the body. Reinstall the float by sliding it back over the stem ensuring that it passes the clips
and allows them to return to their original position.
