Kobold NKP-650110 – NKP Side-Mounted Float Level Switch, M16 Bulkhead, PVDF
The Kobold NKP-650110 is a side-mounted float level switch from Kobold’s NKP series, with an M16 bulkhead connection and PVDF construction. It mounts through a hole in the tank wall and is fixed with a nut, which makes it ideal for thin-walled plastic tanks containing aggressive chemicals or hot liquids.
PVDF offers excellent chemical resistance and a higher temperature rating than polypropylene, so this model suits acids, alkalis, solvents and process liquids up to 100 °C. The bulkhead seal is FKM (FPM), which also resists aggressive media. A hinged float with a magnet switches a hermetically sealed reed contact as the level passes the switch point. The function can be changed between normally open (NO) and normally closed (NC) by rotating the switch 180°.

Choosing the Right NKP Version
- NKP-650110: M16 bulkhead, PVDF, cable variant (this item)
- NKP-640110 / NKP-64011.6: M16 bulkhead, polypropylene
- NKP-25011.6: 1/2″ NPT, PVDF
- NKP-24011.6: 1/2″ NPT, polypropylene
Choose PVDF for aggressive chemicals or higher temperatures. Note that the PVDF float needs a liquid density of at least 0.95 kg/dm³, so it isn’t suitable for light liquids. Our sales team can help you confirm the right version.
