Kobold NKP-65013 Product Overview
The Kobold NKP-65013 is a high-grade, side-mounted plastic float level switch explicitly designed for aggressive chemical environments, high-purity media, and elevated-temperature liquid monitoring. Constructed entirely from premium Polyvinylidene Fluoride (PVDF), this compact switch features a space-saving M16 bulkhead mounting configuration and an integrated 3-meter (10-foot) cable. It is optimized for small tanks, dosing systems, and chemical processing apparatus where top or bottom entry is restricted.

Enhanced PVDF Chemical and Thermal Resistance
Unlike standard polypropylene models, the full PVDF wetted assembly of the NKP-65013 ensures exceptional structural, dimensional, and chemical stability in harsh industrial environments. It reliably withstands fluid temperatures up to 212°F (100°C) and handles highly corrosive fluids, including concentrated acids, bases, and organic solvents. The internal reed switch is hermetically sealed within the PVDF core, fully isolated from volatile process fumes and fluid ingress.
Reversible Contact Architecture and Compact Geometry
The NKP-65013 operates via an adaptable hinged float layout that supports both normally open (N/O) and normally closed (N/C) electrical signal architectures. Instead of requiring separate model profiles, the user can easily invert the switch behavior simply by rotating the device housing 180 degrees about its horizontal axis during mounting. The space-saving M16 bulkhead connection allows the switch to be secured quickly to thin-walled chemical tanks or specialized equipment with a tightening torque of 4 N·m, while the 3-meter cable simplifies connection to remote control blocks or PLCs.
