Specifications
LRF0816C is a 1535 nm pulsed distance-measurement module. Its assigned laser source is ER300; receiver-component data below come from the supplied APD-A13B001 R01 document. The three specification levels describe different assemblies and measurement conditions.

Source clarifications
The current PDF shows a six-contact connector but describes only five contacts. No sixth-contact function is inferred. Its average-power row leaves the frequency after “@” blank; no measurement rate is assigned to that power figure.
