Industrial Network Solutions

For plants to become information driven, they need a strong foundation consisting of one industrial network architecture.

Selecting the right sensor or switch depends on what must be detected, the operating environment, and how the data will be used. Key considerations include sensing range, target material, environmental conditions, safety requirements, and network or controller integration.

Rockwell Automation offers a broad portfolio of sensors and switches designed to align with Logix architectures and Integrated Architecture® systems—helping simplify device selection today while supporting long‑term scalability and system consistency.

Condition‑sensing devices continuously monitor asset health indicators such as vibration, temperature, pressure, or electrical current. When combined with analytics and software, this data enables early detection of abnormal behavior, so maintenance teams can address issues before failures occur.

This predictive maintenance approach helps reduce unplanned downtime, extend equipment life, and lower overall maintenance costs while improving operational reliability.

Many Rockwell Automation sensors and switches support EtherNet/IP™ connectivity, allowing seamless communication with controllers, drives, and software platforms. This enables real‑ diagnostics, simplified wiring, and a real timed easier system expansion within an Integrated Architecture® environment.

Network‑connected devices provide greater visibility into machine performance and support faster commissioning, troubleshooting, and data‑driven decision‑making.

Presence sensing devices—such as safety light curtains and area scanners—detect personnel from entry around machinery. When properly integrated into a safety system, these devices can initiate machine stopping functions while helping maintain productivity.

Designed to support functional safety standards, presence sensing solutions help reduce workplace risk, improve hazard protection, and support safer machine operation in industrial environments.
