Details: LFL4-*K-A2-*****
Function
The device has an initiator built into a PP float. This initiator switches in in the event of deviation from the horizontal position. A switching ball moves along an axis in the float and generates the switching operation in the initiator inductively.
The switching output of the device has a PNP output stage.
