The ingress protection to EN 60529 against external inuences 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 specications see the corresponding WIKA data sheet and
the order documentation.
