Specifications
LRF0310C is a 1535 nm pulsed distance-measurement module. Its assigned laser source is ER100; receiver-component data below come from the supplied APD-A13B001 R01 document. The three specification levels describe different assemblies and measurement conditions.
1. LRF0310C module specifications
Source clarifications
The current PDF range cell states a 2.3 × 2.3 m reference target, while its parenthetical condition names a 2.3 × 4.6 m board or vehicle. The row heading gives visibility ≥5 km; the cell gives ≥8 km and relative humidity ≤60%. These source descriptions are not combined into a new acceptance condition. Its interface description cells are also misaligned with several pin names; consult the confirmed connector record before wiring.
