Product overview
The Meskernel LDK-40-20HZ is an optical laser ranging module with a 0.03-40m measurement range, ±1~3mm accuracy and a 20HZ measurement frequency. Its visible red laser operates at 610-690nm and is Class II under IEC 60825-1:2014. Measuring 48*26*13mm (L*W*H), the compact module suits installations with limited space. It provides TTL UART serial port digital output for industrial automation and is usually used for storage measurement, mid-range measurement, height measurement, and 2D and 3D scanning.
The module operates from DC 2.5V~3.6V, with a TTL communication level of 3.3V and a default baud rate of 115200 bps. It supports TTL, RS232, RS485 and USB interfaces and usually requires RX, TX, GND and VCC connections. Working temperature is 0~40 °C (32-104 °F), while storage temperature is -25~60 °C (-13~140 °F). An optional custom IP54 shell supports easier mounting. Customization options include range, accuracy, frequency and communication parameters. The module comes in neutral packing with a 12-month warranty.
