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, item 6.3.2 relating to the nominal range.
