Water Level Sensor Float Switch - P43
Description:
P43 Water Level Sensor Float Switch is a mechanical, non-electronic liquid level sensor that operates using a magnetic float mechanism. It is designed to detect the presence or absence of liquid (usually water) within a tank, container, or reservoir. The float switch works as an on/off switch that opens or closes a circuit depending on the water level — making it ideal for water level monitoring, overflow protection, and automatic pump control systems.
Features:
1. Accurate Liquid Level Detection – Simple open/close switch mechanism
2. Configurable NO/NC Operation – Change state by inverting float
3. Mechanical Reliability – No electronics, resistant to electrical noise
4. Easy Integration – Works with relays, controllers, microcontrollers, or alarms
5. Sealed Waterproof Design – Suitable for long-term immersion
6. Corrosion-Resistant Materials – Ideal for water and light chemical use
7. Easy Installation – Vertical mounting through tank lid or side
