Functional Description
The source explicitly states support for both single-shot and continuous ranging modes.
The source states integration into real-time data-acquisition systems through standard interfaces such as UART.
The optical-window guidance recommends H-K9L glass, a wedge-angle tolerance of no more than 3 arcminutes, and an 855-955 nm anti-reflection coating with source-stated transmittance of at least 99.5%.
Electrical Interface Definition

Direct Time-of-Flight Ranging
The LRF200H model document identifies the product as direct time of flight (DToF). It determines distance from the delay between an emitted optical pulse and the accepted return.
R = c × Δt / 2R: one-way distance · c: propagation speed · Δt: measured round-trip delay
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.

Source-stated application context
Application labels indicate where the source proposes evaluation; they do not prove fitness without system testing.
- Land-transport vehicle positioning and collision-avoidance monitoring
- Overhead bridge-crane positioning and collision-avoidance monitoring
- Autonomous systems
- Industrial automation
- Intelligent transportation
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 Class 1?
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 documents control wiring and interface release?
The ordered connector drawing, pin definition and approved interface document control the design.
