The ingress protection to EN 60529 against external influences depends
on the basic instrument and is found in the respective data sheet.
The limit switches can be used in the range from -20 to +70 °C. Where
the permissible temperatures for the basic instrument (see data sheet)
deviate from this range, the lower values are valid.
For further specifications see the corresponding WIKA data sheet and
the order documentation.
