Specifications
LRF0405C is a 1535 nm pulsed distance-measurement module. Its assigned laser source is ER200; receiver-component data below come from the supplied APD-A13B001 R01 document. The three specification levels describe different assemblies and measurement conditions.
1. LRF0405C module specifications
Source clarifications
The current PDF lists DC 3–5 V in the specification table and 4.5–16 V in the interface table. It names FWF08002-S06B13W5M in the specification table and A1257WR-S-6P in the interface section, with a six-contact drawing but five described contacts. These entries document an unresolved source/version inconsistency, not a verified wiring specification.
