Temperature sensor d=18mm "Temp-Optimizer" Voca

Thermocontact set to attach to the motorcycle's water circuit and act as a switch.
The supplied thermocontact is 60-70, it activates at 70ºC and disconnects when the water drops to 60ºC. This system is widely used to control the radiator fan.
VOCA develops this kit to control your electric water pump.
When the engine water heats up, the thermocontact activates the water pump, and it turns off if it cools down too much.
Very practical so that the electric water pump, the fan, or whatever you connect, does not run when the engine is cold.
It greatly facilitates the rapid heating of the engine and maintains it.
The connector to the water hose has an outer diameter of 18mm.
