Banner Adds IO-Link to K50R Radar Sensors

The K50R radar sensor is Banner’s alternative to long-range ultrasonic sensors, which can be prone to failing in a blast of steam, a dust storm, or bright shop lights. The K50R radar sensor navigates these environmental challenges with radar precision, and now gets a major usability boost thanks to IO‑Link. With new IO-Link availability, users can swap out the sensor without rewiring, tweak parameters remotely, and extract the kind of diagnostics you’d normally only get with a PLC programmer.

K50R Series Radar Sensors

The K50R Radar Sensor with IO‑Link marries Banner’s reliable radar detection (50 mm to 5 m range) with IO‑Link’s smart configuration layer. That means you get plug‑and‑play module replacement, centralized diagnostics, and field‑friendly fine‑tuning—all without breaking your control system. Its compact IP67 housing and wide -40 °C to 60 °C rating ensure it stands up to tough environments.

IO‑Link Configuration and Diagnostics

When used with an IO-Link master like the DXMR90, the K50R sensors become a fully integrated part of the control system. Engineers can dial in settings like beam angle or detection thresholds without leaving their workstation, and tasks like firmware updates or sensor recalibration can be done on the fly, without pausing production or opening control panels.

With IO-Link, centralized diagnostics are also possible. Operators can monitor sensor health, signal-to-noise ratios, and error conditions directly from a PLC or SCADA interface. When a sensor needs replacing, the system can automatically apply the user-supplied stored settings using IO-Link device IDs, allowing for fast, plug-and-play swaps without needing to rewrite ladder logic. This reduces both downtime and maintenance overhead, streamlining field replacements and getting equipment back online faster.

Ultrasonic Sensor Alternative

The K50R line offers two beam patterns: 40 × 30° for precise detection in constrained spaces and 80 × 60° for wide-area coverage. This means users can choose sensors for spot-on detection or sweeping coverage while still staying in the same compact footprint.

The K50R can be used across a range of industrial and commercial settings where traditional sensors often fall short. In dock door management, it reliably detects the presence of vehicles and pallets without needing reflectors or conveyor systems, enabling smoother logistics without added infrastructure. For tank level monitoring, whether dealing with liquids or bulk solids, the radar technology remains accurate even when foam, condensation, or steam would disrupt ultrasonic performance.

In mobile robotics, the sensor enhances safety by giving AGVs and AMRs dependable obstacle detection, even in dusty or cluttered environments that typically confuse optical sensors. And in applications like drive-thru lanes or EV charging bays, the K50R delivers precise vehicle detection while minimizing downtime caused by false trips. In every case, the addition of IO-Link means remote diagnostics and configuration are just a few clicks away, reducing the need for maintenance calls and simplifying support across distributed installations.
