I have no clue of the PCB where this component was. The reference H400 60 and a logo that is unreadable are located in the top of the package. I didn't found any datasheet or valuable information in google. There's a metal holder and a small cylinder inside the part.
The small cilinder appears to be made by two materials.
The inside material is condutive.
The outside material is isolant.
I can't measure any capacitance in the cylinder.
Thanks in advance.
