Detailed LRF0816C Specifications

The technical material below is retained for this model only. Do not transfer a range, pulse, interface, mechanical or safety value from another 1535 nm product.

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.
