■
Applications
Typical applications include
automatic vending machines,
photocopiers, small collection tanks,
miniature pumping stations, pilot
plants and similar small system
applications.
Controlling delivery of plating
liquid
Nickel plating liquid is used for
surface treatment of electronic parts.
The liquid is automatically fed into
a plating bath with the LFP-V-2PG
detecting the upper and lower levels.

Miniature Liquid Level Sensors

Operational Description
The stem of these miniature
liquid level switches contains a
hermetically sealed reed switch. The
float contains a permanent magnet.
As the float rises or falls with the
level of the liquid, the reed switch is
activated by the magnet. On most
models, the operation of the switch,
normally open (NO) or normally
closed (NC), is easily changed
by removing a retaining clip and
inverting the float.

Utility design for shock resistive
construction in the float
These miniature liquid level
switches have been designed for
reliable operation in small tanks and
containers. Their rugged design and
careful engineering make them the
Commercial Coffee Maker
The LFS-V-5UN is mounted in the
water tank to detect the lower limit
of the hot water. The LFS-V-5UN is
suitable for food and pharmaceutical
applications
because the
float joints
are plasma
welded and
the surface is
buffed smooth.
