TE CONNECTIVITY SENSORSLIQUID LEVEL SWITCHES FOR
INDUSTRIAL APPLICATIONSTE Connectivity provides reed switch reliability in numerous standard and custom
configurations for liquid level switch applications. Our liquid level switches can bearranged to have normally closed or normally open switch indication with the rise or
fall of liquid. Switch orientation options include horizontal and vertical (top or bottomentry), depending upon the configuration chosen. All of our housings have at least
IP65 enclosure rating and both external and internal fit sensors are available.

DESIGN QUESTIONS?
• What is the switch orientation?
Example: Horizontal, from the top, from the bottom?
• Should the switch open or close when the desired
level is reached?
• Are you sensing a level “full” or a level “empty”
condition?			
• What is your liquid media?
Example; oil, water, etc.			
• What is your desired process connection?
• What are the process temperatures?
• What is the max pressure?			
• What is the desired float material?
