Product overview
The Meskernel LDK-40 laser distance sensor module combines a red semiconductor laser with a compact design for OEM integration into systems and equipment. Intended for industrial automation, it provides UART TTL communication for user-programmed applications, with a serial level of VTTL=3.3V. The module measures 48*26*13mm and weighs 10g. It operates at DC+3.3 V, draws 80mA and consumes 0.27W. Standard supply tolerance is 3.3V±0.3V, and the module is packaged in a Meskernel paper box.
Indoor measurement range is 0.03-60m at 90% reflection, with absolute accuracy of ±2mm and a 3cm blind area. Output frequency is 3Hz; 8Hz operation is available only in fast continuous measuring mode. The red laser has output below 1mW and a Class II safety classification. Operating temperature is 0~40 ℃, with a customized -10 ℃~50 ℃ option. Strong light or excessively high or low target diffuse reflectance increases measurement error to ±1 mm+50PPM. Use a reflector under strong light or poor target diffuse reflectance.
