I'm trying to replace connections between a trunk cable and drop cables in a DeviceNet system. The system is in a high humidity environment, so the current clamps used now are not holding up with the harsh conditions. The plan is to replace the cable with a round cable with t-port taps. The taps are IP67 rating, which can handle full submersion in water for 30 mins. I'm wondering though if it will still hold up in the high humidity environment which is constant. My question is asking if IP ratings correlate with a products ability to tolerate humidity.
