NTC type temperature sensors
for ETC & ERC controllers
Danfoss has selected a programme of temperature sensors to be used with their ETC and
ERC range of controllers.
NTC (Negative Temperature Coefficient)
temperature sensors change resistance with
temperature in a manner compatible with the
controller software.
They are fully compliant with the tolerance
requirements according to IEC 60060-1.
Features
ƒƒ High accuracy in temperature measurement and close tolerances ensure improved control
ƒƒ Plastic moulded sensor case
ƒƒ Insulated connecting cable
ƒƒ Various cable lenghts available
ƒƒ Supplied with rast 2.5 connectors
ƒƒ Poka-yoke (mistake-proof ) cable connection
to the controller

Connectors diagram
Danfoss NTC temperature sensors are clearly
marked for easy identification during the assembly process.
For example, a sensor marked with two blue
stripes as shown in figure 1 is the evaporator or
defrost sensor.
Colour coding on the cable close to the sensor
element is used to differentiate between cabinet,
evaporator (defrost) and condenser sensors even
if the plug part of the cable is not visible.
There are also different connector types or codes
at the plug end of the cable. Using a combination of rib cuts on the connectors ensures correct
connection position to the controller as shown in
figure 2. This is known as Poka-Yoke design.
