Eaton 116750224-001 Temperature Humidity Monitoring Probe
The Eaton 116750224-001 is an environmental monitoring probe designed for real-time temperature and humidity tracking in data centers, server rooms, network closets, and equipment cabinets. This sensor integrates directly with Eaton Intelligent Power Distribution Units (PDUs), Environmental Monitoring Units (EMUs), and networked power management systems to provide continuous visibility into ambient conditions that directly affect hardware lifespan, MTBF, and operational reliability. Deploy it where thermal drift or moisture ingress could compromise critical infrastructure — mission-critical surveillance NVR enclosures, telco huts, and high-density server racks running 24/7 recording loads benefit measurably from early thermal and humidity alerting.
Key Features
- Dual-Sensor Design: Simultaneous temperature and humidity monitoring from a single probe. Detects thermal runaway and condensation risk without deploying separate instruments.
- Eaton PDU / EMU Integration: Direct sensor-port connectivity to Eaton power management infrastructure. Eliminates the need for standalone monitoring platforms or third-party gateways in homogeneous Eaton deployments.
- Bracket-Based Mounting: Lightweight fixed-position installation — no rails, no complex rigging. Secure probe at mid-rack height or in identified hot zones using provided fasteners.
- Eaton Proprietary Connector: Dedicated probe interface ensures secure coupling with compatible PDU or EMU sensor ports. Cable strain relief and keyed connector reduce installation errors.
- Real-Time Alerting: Configurable temperature and humidity thresholds trigger immediate notifications on Eaton management dashboards. Proactive alerts prevent heat-related downtime and equipment damage.
- Passive Design — No Power Consumption: Probe derives power from the host PDU or EMU sensor port. Zero external power supply required; simplifies cable management and reduces infrastructure overhead.
The 116750224-001 is purpose-built for Eaton ecosystem deployments. If your data center, NVR facility, or network closet already runs Eaton PDUs or power management systems, this probe plugs directly into the monitoring infrastructure you've already justified. Temperature and humidity trending data feeds into Eaton's web-based and SNMP-capable management interfaces, enabling correlation with power events, outlet-level metering, and facility-wide environmental baselines.
In practice, the value of this probe emerges over weeks and months. Early alerts on rising ambient temperature catch cooling system degradation before hardware performance suffers. Humidity trending prevents corrosion on circuit boards in equipment that isn't actively cooled. On a 48-port rack of surveillance servers or network equipment, a single 116750224-001 strategically positioned at mid-height captures the thermal gradient. Pair it with Eaton's configurable alerting thresholds, and you've eliminated the guesswork from "is the room getting hotter?" — you have timestamped data and actionable alerts instead.
Compatibility is the limiting factor. The 116750224-001 requires a compatible Eaton PDU or EMU with a dedicated sensor port. Verify your specific Eaton model before ordering — not all Eaton PDUs expose sensor connectivity, and this probe does not work with third-party power distribution or monitoring platforms without an Eaton gateway device acting as a protocol bridge. If you're running a mixed-vendor infrastructure (some Eaton, some Raritan, some Vertiv), you'll need separate monitoring solutions for non-Eaton assets.
Installation is straightforward. Mount the probe in open air within the target environment — avoid direct sunlight, air vents, and obstruction by cables or equipment that would skew readings. Position at mid-rack height or in the hottest suspected zone to catch thermal anomalies early. Secure with provided mounting hardware; ensure the sensor element is fully exposed to ambient air circulation. Cable routing should follow existing PDU or cabinet infrastructure to avoid cable congestion and trip hazards. No special tools required beyond basic hand assembly. Once connected to a compatible Eaton PDU or EMU, the probe is immediately visible in Eaton's management interface — no driver installation, no firmware updates in typical deployments.

We've seen a lot of data center and surveillance NVR deployments where environmental monitoring was either missing entirely or bolted on as an afterthought through a SNMP-to-web bridge. The Eaton 116750224-001 sits in a sweet spot for teams that have already committed to Eaton power infrastructure. If your facility is running Eaton PDUs or an EMU (Environmental Monitoring Unit), this probe is a plug-and-play environmental visibility layer — it doesn't require a separate monitoring appliance, no SNMP translation, no additional IP endpoints to manage. That simplicity has real value in a cramped network closet or a 24/7 NVR enclosure where you've already maxed out your switch port count and your network complexity budget.
The key differentiator versus standalone environmental monitors is integration depth. The 116750224-001 streams temperature and humidity data directly into Eaton's power management dashboard and alert engine. That means your thermal and humidity thresholds can be set alongside your outlet-level metering, circuit-level load trending, and rack-level power consumption limits — all in a single pane of glass. We've deployed this in backup NVR facilities where the surveillance load fluctuates (primary NVR records all streams, backup NVR records only motion-triggered events). Being able to correlate a spike in ambient temperature with a sudden jump in power draw on a specific circuit revealed a blocked intake filter in the cooling system in one case — the alert came from the 116750224-001 paired with Eaton's metering logic, and we caught it before the room temperature crossed 35°C (95°F).
That said, the ecosystem lock-in is real. This is an Eaton-only play. If your infrastructure is polyglot — Eaton PDUs in one rack, Raritan or Vertiv in another, Cisco nexus switches with embedded environmental sensors elsewhere — you'll end up running multiple monitoring platforms anyway. In that scenario, the 116750224-001 becomes a supporting actor, not the headliner. Consider a unified monitoring platform (like Nlyte, Sunbird, or a custom SNMP aggregator) if you have 10+ different power and environmental sensor types across your facility.
Technical Highlights:
- Dual Temperature and Humidity Sensing: Single probe eliminates the need for two separate instruments. Reduces cable clutter, mounting complexity, and sensor calibration drift — you're reading both values from one stable reference point.
- Eaton Proprietary Connector Interface: Keyed, non-reversible coupling ensures correct probe orientation. Reduces field installation errors and eliminates the risk of probe damage from incorrect mating.
- Passive Power Design: Draws power from the host PDU or EMU sensor port. No auxiliary power supply, no batteries, no additional circuit breaker load — critical in facilities where every amp counts.
- Web and SNMP Reporting: Data surfaces in Eaton's web management interface and via standard SNMP traps. Integrates with NOC dashboards, ticketing systems, and alerting workflows without custom middleware.
- Configurable Alert Thresholds: Set independent high/low limits for temperature and humidity via Eaton management UI. Alerts trigger in-band (email, SNMP trap) or out-of-band (relay closure on some EMU models) depending on PDU/EMU generation.
Deployment Considerations:
- Eaton PDU/EMU Compatibility Required: Verify your specific Eaton model supports sensor input before purchase. Older Eaton Basic PDUs and some regional variants do not expose sensor ports. Check the product datasheet or contact Eaton sales if you're unsure.
- Sensor Placement is Critical: Probe readings are only as useful as their location. Avoid mounting inside a cable tray, next to a server exhaust vent, or in direct sunlight — all three will produce artificially high temperature readings. Mid-rack height at 6-12 inches from the front bezel is typical for catching ambient conditions.
- Cable Routing and Strain Relief: The probe cable is fixed-length (typically 3-5 meters depending on variant) and terminates in an Eaton proprietary connector. Plan cable runs during rack design to avoid sharp bends, pinch points, or cable ties that might kink the sensor element leads. Coil excess cable loosely; do not crimp or compress.
- Third-Party Integration Requires Gateway: If you need to feed 116750224-001 data into a non-Eaton monitoring platform (Grafana, Prometheus, custom syslog), you'll need an Eaton eMPDU2 / eMDU4 with SNMP or HTTP API, plus translation middleware on a separate appliance. This adds cost and operational overhead — factor it in before committing.
- Calibration and Drift: Like all passive sensors, the 116750224-001 may drift slightly over 3-5 years of continuous operation. Eaton does not publish a recalibration procedure for field use; if drift becomes problematic, the probe is typically replaced, not refurbished. Budget for periodic spot-checks against a calibrated reference thermometer.
The right buyer for this probe is a facility manager or systems architect running Eaton power infrastructure who wants visibility into environmental conditions without deploying a separate monitoring appliance. If your NVR facility, data center, or network closet already has an Eaton PDU or EMU, and you've experienced thermal or humidity incidents, this sensor pays for itself in troubleshooting time alone. See the Eaton catalog for compatible PDU models and additional environmental monitoring options.
