NTC

3.4.1 Types
There are two types of NTCs.

NTCs for the inductors.

NTCs for the electronic module (ELIN)
3.4.2 Characteristics and assembly
3.4.2.1 NTCs for the inductors
In both IH4-I (previous project) and IH5-I (current project) the NTCs
measure the temperature directly on top of the glass.
The difference lies in the way the NTC is mounted in the inductor
and the fact that they have polarity (i.e. 3 channels for the frying
function NTC).
For mounting purposes, a silicon support bracket is used instead of
a metal spring. This reduces the time taken to assemble the
component.
The external NTC has a 3-wire connector and controls the frying
sensor function.
They are both interchangeable and have a different code number
(internal 2-wire NTC connector and external 3-wire NTC connector)
and can be supplied as spare parts.
