LLC210D3SH, SSt Sensing Limited OPTOMAX LLC210 Series Liquid Level Switch Level Switch, Transistor Output, Threaded Mount,

Reverse polarity, ESD and transient over-voltage protected
Wide supply voltage range
Push-pull output, capable of sinking or sourcing up to 100mA, can directly drive small loads
Optional fail-safe PWM output
Standard and extended temperature ranges available
Polysulfone or Trogamid housing material options
Internal or external mounting options
High pressure option available
Solid state so no moving parts to cause unreliability
Small in size so they can be installed in applications where space is limited
Can detect tiny amounts of liquid when positioned correctly, ideal for leak detection
Fast response time
Repeatable switching point
Built-in output delays available on request for applications where sloshing causes intermittent switching
Very robust permitting use in a wide range of fluids and chemicals
