Details
Built for robotics and automation, the SK100 series delivers up to 100 m ranging with ±3 mm accuracy and flexible industrial interfaces.
Common use cases include level measurement for grain silos and liquid tanks where fast, non-contact distance readings are needed.
UART TTL output makes integration straightforward with Arduino, Raspberry Pi, PLCs, and MCUs for AGV and robot builds.
Long-distance performance supports navigation, positioning, and obstacle measurement tasks across larger work areas.
A 63 × 40 × 18 mm footprint fits tight spaces while maintaining a 100 m range and adjustable 1–20 Hz measurement rate (model dependent).
