NOVA20 is a compact 20-channel multi-point LiDAR that outputs distance, signal strength, channel number, and temperature across a field of view of up to 40°. It is intended for robot obstacle avoidance and drop prevention, platform screen-door foreign-object detection, and space-presence detection.

Both products can serve close-range sensing, but their output forms differ: TF-NOVA uses a line-pattern spot for area ranging input, while NOVA20 outputs channel-tagged distances in multiple directions. Decide which data form the system actually needs first.
View comparison topicTF-NOVA currently lists a 14°×1° line-shaped field, a 14 m specified range, rates up to 900 Hz and UART, I²C and I/O for doors, vehicles or robots needing horizontal area input.
Boundary: A line pattern is not 20 independent angular channels and does not output object classes or safety decisions; verify what the current IP65 statement protects in the formal document.
View model detailsNOVA20 specifies 20 channels with distance, strength, channel ID and temperature output over a channel distribution field up to 40°, fitting close-range tasks that must distinguish several directions.
Boundary: The 1 m range is stated at 10% reflectivity and 100 klux, with a 10 Hz frame rate; no protection rating is stated, and channel count alone does not establish system performance.
