IP65 Outdoor Temperature Sensor ENVIROMUX-STS-O

ENVIROMUX-STS-O IP65 Outdoor Temperature Sensor by NTI

When critical infrastructure such as transformer stations, data centers with outdoor cooling, or industrial facilities operate outdoors, reliable temperature monitoring is essential. 

The ENVIROMUX‑STS‑O from NTI is built exactly for this purpose: a weatherproof IP65 sensor that measures temperatures from ‑40 to +85 °C with ±0.5 °C accuracy – even in rain, snow, dust, or extreme heat. 

Its robust housing (115 x 65 x 54 mm) fully protects the electronics, while the waterproof RJ45 connector with quick‑lock provides a secure link over CAT5/6 cables up to 305 meters. 

No calibration, no external power supply – simply connect it to ENVIROMUX‑2D, ‑5D, or ‑16D, and the system provides both power and data. The digital RS485 signal is immune to interference, ideal for long runs in EMI‑exposed outdoor areas. 

The strength of the ENVIROMUX‑STS‑O lies in its combination of extreme durability and user‑friendliness. With only 14 mA current draw at 5 VDC (powered directly from the ENVIROMUX system), it is energy‑efficient and maintenance‑free. 

The optional ENVIROMUX‑FSC fiber converter extends range up to 2 km – ideal for large‑scale sites or remote measurement points. With an MTBF of over 1.8 million hours and CE/RoHS certification, it is built for longevity and global use. 

Whether in arctic cold storage, desert solar parks, or rainy industrial yards, the sensor delivers precise real‑time readings to the NTI dashboard. Combined with humidity sensors such as ENVIROMUX‑STHSB or alarm modules like ENVIROMUX‑SRN‑BCNL, it forms a comprehensive outdoor monitoring solution. 

The ENVIROMUX‑STS‑O is the reliable guardian of your outdoor infrastructure. No analog signal loss, no delicate components – only precision and protection. Easy to install using screws or adhesive mounting, a waterproof connector, and long range make it the first choice for demanding outdoor applications. 

In times of climate change and extreme weather, preventive monitoring is critical. A data center operator using outdoor air cooling integrated the sensor: during a record heat wave of 48 °C, the system triggered emergency cooling automatically – servers stayed online, preventing losses valued in millions. With the ENVIROMUX‑STS‑O, you invest in operational safety, compliance, and long‑term cost control – 24/7, in all conditions.
