Hi all,
Doing some repair on a circuit board that was inside an industrial robot that I am playing with at home. There is one component on the board I am unfamiliar with.
It is a 3 terminal device that is shaped like 3 vertical cylinders with the middle one being offset and smaller than the outside two. It is enamel dipped like ceramic capacitors. The label on the PCB is "NF1" and the terminals are labeled 1,2,3.
The component sits between the external connector which supplies +24VDC and the connectors which distribute the 24V to various devices inside the robot. The middle pin is tied to a pin on the input connector labeled RG which I believe stands for "Robot Ground". Voltage enters on pin 1, RG is pin 2, and the loads are connected to pin 3.
I don't need to do anything with this, but just had no idea what it was. First though was some sort of 3 terminal fuse?
