Mechanical design
The cable temperature sensor consists of a sleeve (6 mm diameter, 50 mm long), sens-
ing element and connecting cable with ferrules.
The sensing element is accommodated in the sleeve which is flat on one side and to
which the connecting cable is attached.
The sensor is not suited for direct immersion in liquid media (without using a protection
pocket).

Engineering notes
The permissible cable lengths are dependent on the type of controller used. For details,
refer to the Data Sheet of the relevant controller.
Mounting notes
The following mounting choices exist:
• Up to medium temperatures of 85 °C: with plastic cable tie (supplied by thirds)
• Up to medium temperatures of 220 °C: with stainless steel cable tie (supplied by
