Brand Name: Jinhefeng
Model Number: L1-P
Place of Origin: Guangdong, China (Mainland)
L1-P side mount series
Description
Level sensing switch L1P (see Figure 1) for side mount float level switch, one of our popular products. Its
features simple structure,light weight,small volume , N.O or N.C by reversing 180°,it can be easily install and
used, safe and reliable to level control device, it is one mechanical switches, speed, long life, stronger anti-load impact to compared with the electronic switch. It without complex circuit ,will not be disturbed ,easy to
use to control level.
The liquid level switch has polypropylene stem and float. The Polypropylene is typically suitable for use with acidic liquids such as those found in electroplating and metal
cleaning. It is also a great option for lower temperature food operations (up to 105 degree C).

A: The components.
1: The main stem material: PP
2. The float material: PP
3. Assembly: Reed switch magnet ,Epoxy
4. Lead Wire.30 cm(Teflon).
5. Cir-clip
B: Working principle: The float level switch utilize the liquid buoyancy principle, along with the liquid pressure (water level) the float ball will move up and down ,then it will trigger the reed switch that sealed in the the PP stem ,the magnet arm will be affected, and for send the connect (ON
or disconnect (OFF) signal.
C:The installation instructions (see Figure II)
1.on the bottom or the ceiling of the tank,vertical mount, No( open) or NC (closed) due to the installation position..
2. The total length of L1-P is 36 mm , the connect use the M12 stand thread, length is
55 mm
3. Unscrew the nut ,via the hole at the side of the tank, then tighten the nut.
D: Instruction
1: The range of temperature -30 ℃~ 85 ℃
