Pulsed Time-of-Flight Engineering Context
The public LR2000E2 source used here does not state the internal timing architecture. The equation below describes pulsed time-of-flight ranging generally and is not presented as an additional LR2000E2 specification.
Real performance also depends on target reflectivity and area, incidence angle, atmospheric attenuation, receiver aperture, background light, detector response, timing thresholds and contamination of the optical path.
What the verified data supports
These are traceable design inputs, not unsupported superlatives or guaranteed field outcomes.
Performance envelope
Ranging Range: 4–2000 m · Ranging Accuracy: ±1 m (≤400 m); D × 0.4% (400 m < D ≤2000 m)
Timing and output
Ranging Frequency: 2–10 Hz
Electrical integration
Supply Voltage: 3.3–5 V
Mechanical integration
Envelope, mass and environment require confirmation before design release.
Source-stated application context
Application labels indicate where the source proposes evaluation; they do not prove fitness without system testing.
The reviewed public source used for this page does not establish a model-specific application list. Share the target, environment, interface and acceptance test for an engineering fit review.
Confirm before selection
- Define target size, reflectivity, incidence angle and required detection probability.
- Reproduce sunlight, visibility, weather and optical-window conditions in acceptance testing.
- Verify voltage tolerance, peak current, grounding, interface levels, baud rate and connector revision.
- Separate accuracy, repeatability and displayed resolution in host requirements.
- Confirm mounting datum, boresight, field of view, enclosure sealing and thermal path.
- Assess accessible emission and labeling again after integration into the finished equipment.
Questions to resolve before design release
Does the maximum stated range apply to every target?
No. Use the reflectivity and environmental conditions shown beside the range row. Smaller, darker, oblique or partially obscured targets and degraded visibility can reduce received signal.
Are resolution, repeatability and accuracy interchangeable?
No. Resolution is the reporting increment, repeatability describes variation under repeated conditions, and accuracy describes closeness to the reference distance under the stated test method.
Is the finished product automatically assigned the module laser class?
No. A module-level source statement does not replace the accessible-emission and failure-condition assessment of the finished equipment, its window, controls, service access and labeling.
Which document controls wiring and protocol release?
The ordered connector drawing, pin definition and protocol revision control the design. This marketing page deliberately does not expose hidden protocol commands or infer an interface value that is absent from the model source.
Product evidence and general technical context
The model PDF controls product claims. Public references support only the general engineering explanations and must not be used to infer a missing model value.
