Keep a closer watch on thermal conditions inside the rack with the Vertiv Liebert SN-T modular temperature sensor. Designed for Liebert MPX and MPH Rack PDUs, it supports a custom string layout through two connection points, so you can position sensing across the areas most likely to experience hot spots. That flexibility matters in dense environments where a single reading is not enough. By placing the sensor where airflow changes, cable congestion, or high-load equipment can raise temperatures, teams get more useful visibility into rack-level conditions. The result is earlier awareness of thermal drift and better support for uptime-focused operations. The SN-T is a practical fit for infrastructure teams that want targeted temperature monitoring without adding complexity. Its compact form factor and included mounting options make installation straightforward, while the modular design helps tailor coverage to the rack layout you already have. For environments where temperature trends affect service continuity, this sensor adds the kind of detail that supports better decisions.
