AUMOVIO Engineering Solutions offers ARS 408-21 as an industrial radar. Lodda supplies it on the agency line.
ARS 408-21 measures distance, radial speed, and angle on natural targets, without a reflector, using fast FMCW ramps. AUMOVIO describes a real-time scan on the order of 17 cycles per second, and the datasheet puts the near-and-far cycle at about 72 ms. Lodda supplies the sensor and supports the engineering around it. The design is AUMOVIO / Continental.
Read the range in two layers. The standard far range on the datasheet is 0.20–250 m. The near field is shorter and depends on angle: 0.20–70 m / 100 m from 0° out to ±45°, and 0.20–20 m at ±60°. A special software version is described up to 1,200 m, and only for high-RCS objects with a free field of view.
The industrial -21 build exposes a CAN protocol, with user settings for sensor ID, sensitivity, and collision-warning regions. Supply is +8.0–32 V DC. Typical power on the datasheet is 6.6 W at 12 V, with a 12 W peak.

Notes
- 1.Far range of 250 m is the datasheet figure for natural targets. A configurator listing also prints 0.2–260 m for a standard sensor; this page follows the datasheet. Near range shortens as the angle opens. The datasheet separates far and near resolution and accuracy; the full table is the manufacturer’s.
- 2.1,200 m is a special software version, described for objects with high RCS and an unobstructed field of view. It is a conditional range.
- 3.Power, temperature, and ingress are copied from the AUMOVIO datasheet for ARS 408-21. They are manufacturer statements. Lodda does not recast them as its own certification.
