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.
