Series LS-20 HORIZONTAL SINGLE POINT LIQUID LEVEL SWITCH
■At the heart of this unit is a magnetically sensitive switch containing two magnetically polarized contacts, which are attracted to each other when exposed to a magnetic field. When the contacts come together an electric current can flow. When the magnetic field is removed the contacts separate and electrical current flow is interrupted.
■The major components of the LS-20 are the specially oriented magnet within the float and the switch within the float shaft. The normally open configuration occurs when the float hangs down at approximately a 60 O angle. As the float travels up through its arc due to rising liquid level the magnetic field closes the switch contacts completing the circuit. As the level lowers the float swings down and the contacts open breaking the circuit. Normally closed operation is achieved by installing the entire switch upside down causing the float to rest on the body. The switch contacts will be closed when the level is below the switch and open as the level rises.
■The unique Micro Latch function holds the switch closed for approximately 22 Degrees of arc before it opens. This helps prevent excessive tight band switch cycling found in other types of switches. In water, this translates into 1/2 to 3/ 4 of an inch of latch before release.
■The LS-20 is a small horizontally mounted hinged type single point magnetically activated liquid level switch capable of switching 10 watts up to 200Vdc or 12VA up to 230Vac. It is available in normally closed or normally open single pole single throw dry contact configurations. The LS-20 is ideally suited for mounting through tank walls in narrow tanks, close to corners, or between obstructions. This switch is designed for use with light loads such as micro processor analog inputs and outputs, logic control relays (similar to our CR-100 panel mount control relays and control modules), piezo electric buzzers, and small indicator lights. Materials of construction are unpigmented natural Polypropylene and PVDF. The LS-20 is economically priced and ideally suited for OEM applications. Custom design variations are available upon request.
