ENVIROMUX-STS Temperature Sensor

ENVIROMUX-STS Temperature Sensor for 0–50 °C from NTI

In server rooms, control cabinets, or production environments, a temperature difference of just a few degrees can decide between stability and downtime. 

The ENVIROMUX‑STS from NTI is the smart, cost‑effective solution for precise temperature monitoring in the 0–50 °C range – exactly where most critical applications operate. 

With an accuracy of ±0.5 °C and a digital RS485 output signal, it delivers reliable data even over long CAT5/6 cables up to 305 meters. 

No calibration after installation, no external power source – simply plug it via RJ45 into an ENVIROMUX‑2D, ‑5D, or ‑16D unit, and the system provides both power and communication. The sensor is immune to electromagnetic interference, making it ideal for noisy industrial environments or densely packed data centers. One IT administrator noted, “We installed 20 STS sensors in our main server room in under an hour, with no tools. Since then, no false temperature alarms – and a potential hotspot was spotted in time.”

The ENVIROMUX‑STS is built for longevity and ease of use. With an MTBF of over 3.7 million hours and CE/RoHS certification, it’s designed for continuous operation. Power consumption is only 20 mA @ 5 VDC, supplied directly by the ENVIROMUX system. 

The optional ENVIROMUX‑FSC fiber converter expands range to 2 km, making it ideal for distributed facilities or outdoor enclosures. Whether in offices, warehouses, or data centers, the sensor installs easily – mounting hardware is included – and integrates seamlessly into existing NTI monitoring infrastructures. 

When combined with humidity sensors like the ENVIROMUX‑STHSB or signal modules such as the ENVIROMUX‑SRN‑BCNL, it enables a comprehensive environmental monitoring solution. 

The ENVIROMUX‑STS is more than a temperature sensor – it’s a key component for proactive maintenance and system stability. No analog signal loss, no recalibration headaches, no complex cabling. Simply connect, measure, and protect. With a 96 kbps data rate, updates are instantaneously reflected in the ENVIROMUX dashboard for centralized threshold, trend, and alarm management. 

In an era of rising energy costs and tighter uptime requirements, precise temperature control is essential. A manufacturing plant integrated the sensor into its production line; whenever the temperature exceeded 45 °C, the system automatically activated ventilation – downtimes from overheating dropped by 85 %. With the ENVIROMUX‑STS, you invest in stability, efficiency, and safety – without compromise.
