Product overview
The Meskernel LDJ-P4 200 measures distance using phase-shift ranging: it modulates the emitted laser beam and calculates distance from the phase difference between the outgoing beam and its reflection. An IP54 industrial-grade housing encloses the sensor in an 85x62x22mm body, measured as length × width × height. Weight is 92g±1g, and the working temperature range is -10~50℃. Measurement time is 0.05~4 seconds. The laser is CLASS-II according to IEC 60825-1, with power below 1mW.
Red laser versions provide 1–3 mm measurement accuracy and suit indoor work or shaded outdoor areas with adequate visibility. Green laser versions provide 3–5 mm accuracy and suit outdoor work in bright sunlight. RS232, RS485 and UART interfaces support connection to industrial control systems, while Arduino, Raspberry Pi and ESP32 compatibility supports custom measurement development. Applications include building measurement, crane positioning, conveyor monitoring, robotic positioning and automated material handling, as well as railway track alignment, bridge inspection and tunnel clearance measurement.
