Monitor the level of liquid in your tank with this switch from Sensata Cynergy3. It uses an optical sensor that consists of an infrared emitter and a cone-shaped sensing tip. When the tip is immersed in liquid, beams of light are released on the surface. The sensor measures the reflection and refraction of the light to determine if fluid is present or absent. You can use this switch for fluid regulation in demanding industrial applications like the marine and pharmaceutical industries.

• Tough polysulfone housing material is resistant to impact and heat
• Supply voltage range of 10 to 28V DC for versatility
• Resistant to false triggering caused by foaming for enhanced accuracy
• Wide operating temperature range of -40°C to +125°C for use in hot and cold environments

This switch comes with three colour-coded wires so you can easily attach them to the appropriate circuits. As the conductors are made from tinned copper, they have excellent conductivity for reliable transmission.
