Float Level Switch SEN-PPI110
Float Level Switch SEN-PPI110
Overview
Mechanical liquid level detection switch
Uses floating mechanism with magnetic reed switch
Designed for water tanks & liquid level control
Works without continuous power (passive device)
Working Principle
Float contains a magnet inside
As liquid level rises/falls, float moves
Magnetic field activates reed switch
Output changes:
ON level reached
OFF level dropped
Provides ON/OFF signal for level detection
