Product description
1)
Maintaining the housing protection IP 66 or IP 67 requires the use of a seal that correctly fits the cable in
the cable entry. If the supplied seal does not fit, a suitable seal must be provided by the customer.
2)
In compensated temperature range of 0°C … +80°C, reference temperature 20°C
3)
Acc. to IEC 770, point 6.3.2 relating to the nominal range
