Set the working distance and margin for the real target reflectivity first, then compare weight, enclosure, protection, interface and update rate. These are current specification differences, not a performance ranking without matched-condition tests.
TFA170-L is currently specified at 0.1–170 m, about 10 g, RS-232 and 12 V for systems that need long-range input while tightly controlling payload.
Boundary: It has no enclosure; verify output rate and delivered version, and validate structural, water and thermal protection for outdoor use.
View productTF03 is currently specified at 0.1–180 m and IP67 with UART, CAN, RS-232 and RS-485 for outdoor tasks that can carry about 86 g and need enclosure and interface choice.
Boundary: High rates must match baud rate and interface version; target surface, background, vibration and control latency still require system validation.
View productTFA300 is currently specified at 0.1–290 m, up to 10000 Hz and IP67 with UART and CAN for tasks where long range and fast sampling both matter.
Boundary: Headline maxima do not replace tests with the real target and environment; verify power, data-link bandwidth, mounting stiffness and version together.
View productTF350 is currently specified at 0.2–350 m and IP67 with UART, CAN, RS-232 and RS-485 for platforms prioritizing range margin and interface choice and able to carry about 224 g.
Boundary: Greater range comes with more weight and size; do not select by maximum range alone—validate target, environment, mounting and system stopping or control margin.
