FAQ

What is the maximum range of the LRF50H?

The published range is 0.05–50 m (90% reflectivity); 0.05–15 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity. The source marks this parameter as measured at 25°C in an indoor environment.). A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.

Which interface does the LRF50H use?

The published communication interface is UART.

What laser wavelength does the LRF50H use?

The published wavelength is 905 nm; laser safety entry: Class 1.

How much does the LRF50H cost?
