Platinum Temperature Sensor in Thin Film Technology
MN 420
M series platinum temperature sensors are characterized by long-term stability, precision over a broad temperature range
and compatibility. They are used in particular for applications with high consumption volumes, typically in the automotive,
white goods, ventilation, heating and energy generation sectors as well as in medical and industrial equipment. The type of
connection technology facilitates the construction of elements with leads up to 200 mm in length.

1. To avoid shear forces on the connection area,
the connection wires may be neither split or bent.
The bending may only take place 3 mm after the
element, using a bending or splitting tool.
2. Other nominal values, lengths and temperature
coefficients on request.
3. Due to a production-caused oxide layer coating
the leads, soft-soldering is restricted.
Other tolerances, values of resistance are available
on request.
