Omron, 61F-GPN-BT / -BC Series

Outputs can be set to self-hold at ON or OFF using special circuits.
Adjustable sensitivity, with an operating resistance range of 0 to 100 kΩ, allows use for a wide variety of liquids.
Relay contact chattering conventionally caused by waves eliminated using open collector output, reducing contact wear.
Meets CE marking and is a UL recognized component.
