Details

Designed for industrial distance measurement, the SK‑Pro Series combines a visible aiming laser with strong outdoor light immunity and flexible range options.

Get fast, stable measurements with up to 30 Hz output, 1 mm accuracy, and interface choices like RS485 or 4–20 mA for easy integration.

Built for demanding automation tasks, the SK‑Pro Series prioritizes long range, high precision, and reliable performance in complex environments.

Choose the range that fits your setup—30 m, 60 m, or 100 m—then mount securely for consistent distance feedback in robotics and automation.

Common deployments include surveying and mapping, warehousing and logistics positioning, rail monitoring, and port measurement.

Suitable for infrastructure and heavy-industry measurement, including rail/track monitoring and large tank distance or position detection.

From material-level robotic arms to crane anti-collision and tunnel safety monitoring, the sensor supports a wide range of automation needs.

Outline dimensions and mounting references help confirm fit for enclosures, brackets, and machine integration.
