Environmental ratings and installation limits
The 6AG1952-1KT00-4AA0: Rated for ambient temperatures from 0 °C to 60 °C, which covers most control cabinet conditions without derating. The maximum installation altitude is 5 000 m above sea level — important if your site is at high elevation. At altitudes above 2 000 m you need to derate the maximum temperature: above 2 000 m reduce Tmax by 10 K, above 3 500 m reduce by 20 K. Type 1 protection against fouling, conformal coating Class A. Handles Level GX group A/B gases, salt spray, and oil.
Sourcing reality
This is an active Siemens part — no end-of-life or restricted availability. If you need a SIPLUS coated variant for a new build or a line-down replacement, we can quote against an RFQ. The standard uncoated version (6ES7952-1KT00-0AA0) is more widely stocked, but this coated version is the one to specify when the spec calls for conformal coating. No direct second-source equivalent exists; the part is Siemens-only.
