Product description
DK CMC III Temperature sensor, WHD: 80x28x40 mm
Fast, direct CAN bus connection with 2 x RJ45 interfaces enables immediate integration into existing CAN networks, reducing commissioning time and wiring errors. This is ideal for IT enclosure monitoring across data centers and industrial facilities, delivering faster time-to-value. The compact 80x28x40 mm housing houses an internal NTC resistor for accurate temperature readings in tight spaces, while operating between 0 and 55 °C with 5 to 95% RH non-condensing, ensuring reliable performance in harsh environments. The supply includes a sensor, mounting plate, assembly parts, an external temperature sensor with connection cable and connector (NTC sensor 1.80 m; max 2 m), reducing on-site procurement delays and simplifying installation. Compatibility with IoT interfaces and scalable network architecture supports growth from single cabinets to multi-site facilities. Material choices (Front: smooth plastic; Enclosure: textured plastic) and color codes (Front: RAL 9005; Enclosure: RAL 7035) ensure seamless integration into existing enclosures and branding. With cradle-to-gate PCF of 0.8 kg CO2 eq (Cat B) and packaging of 1 piece, the device supports sustainable procurement and straightforward lifecycle assessments. Overall, this sensor enables efficient temperature monitoring without sacrificing reliability, making it a practical choice for enclosure management in IT racks, industrial cabinets, and facility networks.

FAQs
Begin by mounting the sensor on the provided mounting plate and attaching the required assembly parts. Connect the external temperature sensor via the 1.80 m cable (up to 2 m total) to the NTC input, then run the 2x RJ45 CAN bus connections to your CAN network. The unit supports plug‑and‑play detection and integrates quickly with IoT interfaces, minimizing commissioning time.
It combines a compact 80x28x40 mm form factor with an internal NTC resistor for accurate temperature sensing in tight IT cabinet spaces. Operating from 0 to 55 °C and 5 to 95% RH non‑condensing, it provides reliable readings across IT and data center environments. Direct CAN bus connectivity and IoT compatibility enable centralized monitoring and alerting.
The system supports up to 32 participants per IoT interface and up to 32 PU devices in the CAN network, with a maximum of 4 PU compact units and 16 PDU devices. This structure allows scalable deployment from a single enclosure to complex data center or facility networks while preserving performance and reliability.
The DK 7030.110 is associated with ETIM 9 EC002627 and ECLASS 8.0 27189253 classifications, ensuring interoperability in industrial catalogs and procurement systems. It carries a manufacturer specification as a Rittal temperature sensor for enclosure monitoring, with EAN 4028177659483 and CN/HS references for logistics and compliance workflows.
By enabling fast installation, reliable enclosure monitoring, and scalable network integration, the sensor reduces commissioning time, minimizes downtime, and supports proactive maintenance. Its robust environmental performance and bundled mounting hardware lower installation costs, while IoT and CAN bus compatibility align with digitalization initiatives and energy-management strategies.
