Conductive Level Controller 61F-GPN-BT / -BC

• 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.
