Rittal 7030130 CMC III vandalism sensor - CAN bus

Direct CAN bus connection via two RJ45 interfaces enables fast, plug‑and‑play integration with the processing unit (PU). The immediate benefit is reduced commissioning time and simplified topology, since sensors can be snapped into a bus and auto‑detected rather than wired individually. This is especially valuable in IT racks and industrial cabinets where uptime hinges on quick sensor installation and reliable data flow. By avoiding bespoke wiring harnesses, you also cut on-site errors and spare parts. Scalability and bus architecture: The DK 7030.130 supports up to 32 IoT interface participants, 32 PU devices, and 16 PDU devices per system, allowing you to grow your monitoring network without reconfiguring the core controller. In practice, this means you can monitor multiple enclosures from a single CAN bus, saving rack space and lowering wiring complexity. The system supports bus chaining and direct connections, facilitating modular deployments from a single cabinet to an entire data center. This aligns with IT asset management and predictive maintenance workflows. Measurement capability and environmental resilience: Acceleration measurement detects tampering events or impacts on enclosure lids and doors. With an operating range of 0 to 55 °C and 5 to 95% RH non-condensing, the sensor remains reliable in harsh industrial environments. The compact WHD 80x28x40 mm footprint and the contrasting color scheme (Front: RAL 9005; Enclosure: RAL 7035) ensure easy installation and quick visual checks during audits. Durable plastics and mounting accessories support long service life. Installation and maintenance benefits: The device ships with a mounting plate and assembly parts, making wall or panel mounting straightforward. Direct CAN bus connection avoids extra adapters, reducing potential points of failure. The CMC III sensor can be linked with IoT interfaces to form a bus, enabling remote monitoring, data logging, and condition-based maintenance. Regular firmware updates and centralized management streamline compliance reporting and asset health reviews. Industry context and best practices: For IT and industrial facilities, zero-touch provisioning and predictable data latency are critical. The CMC III sensor family fits into standardized enclosure ecosystems and aligns with procurement classifications ETIM EC002627 and ECLASS 27189253, easing parts sourcing. The 1‑piece pack and compact form factor reduce logistics costs and support fast replacement during audits or capacity upgrades.
