The Meskernel LDLG-P4 is an industrial-grade High Frequency Ranging Sensor engineered for precision distance measurement in demanding environments.
Built on proven iToF (Indirect Time of Flight) technology from the LDL40 series, the LDLG-P4 integrates a green laser beam, a durable IP54-protected aluminum housing, and a 100 Hz high-speed measurement rate.
It delivers fast, stable, and accurate distance readings even under strong ambient light, vibration, or dusty industrial conditions.
To meet different application needs, the High Frequency Ranging Sensor series is available in multiple ranging versions — 40 m, 60 m, and 100 m — all maintaining consistent measurement precision and signal stability.
