Applicable scope and usage limits
Applicable scenarios
Suitable for water-surface, liquid-level and outdoor short-range industrial measurement.
Condition: Bounded by the range, accuracy and operating conditions in the product datasheet.
Not applicable

Condition: If the target requirement exceeds the specification boundary, complete a selection review or contact technical support first.
Filtering 10–50 m tasks by range and protection
This topic addresses the requested 10–50 m selection question, but not every candidate reaches 50 m. Eliminate by real working distance first, then compare weight, enclosure, protection, interface and power.
View comparison topicTFS20-L
An ultra-light 20 m-class module
TFS20-L is currently specified at 0.2–20 m, about 1.35 g and 3.3 V with UART and I²C, fitting payload-critical systems that provide their own structural protection.
Boundary: It has no enclosure, and low-reflectivity targets or strong ambient light reduce usable range; do not treat the 20 m headline as a guaranteed working distance in every site.
View model detailsTFmini Plus
Compact IP65 sensing within 12 m
TFmini Plus provides 0.1–12 m single-point ranging, IP65 and several board-level interfaces for compact equipment whose real distance stays in the short-range band.
Boundary: It is not a 50 m candidate; level or dusty applications also need separate checks for target surface, contamination, cleaning and maintenance.
View model detailsTF02-Pro
Up to 40 m with a high update rate
TF02-Pro is currently specified at 0.1–40 m, up to 1000 Hz and IP65 for tasks beyond 20 m that use UART, I²C or I/O.
Boundary: The 40 m figure is a specification boundary, not design margin for every target and environment; it is not native RS-485, so verify controller and cabling.
View model detailsTF02-Pro-WCurrent model
25 m-class RS-485 with a dust-protection path
TF02-Pro-W is currently specified at 0.1–25 m, RS-485, 7–30 V and IP5X, making it a candidate for industrial level tasks needing a bus and dust-oriented enclosure.
Boundary: IP5X is not a waterproof claim; account for its roughly 90–92 g weight and up-to-4.8 W power in mounting, supply, cleaning and maintenance.

What is the maximum measurement range of the TF02-Pro-W?
The TF02-Pro-W achieves a maximum range of 25 m at 90% reflectivity (indoors at 0 Klux or outdoors at 100 Klux), and 12 m at 10% reflectivity with low-reflective targets. At 1 cm distance resolution and ±1% accuracy beyond 6 m, it is suitable for level detection and industrial ranging applications requiring extended reach.
What communication interfaces does the TF02-Pro-W support?
The TF02-Pro-W uses RS-485 serial communication with a default baud rate of 115,200 bps, 8 data bits, 1 stop bit, and no parity. The 1.2 m cable is included, and the RS-485 interface is specifically designed for industrial scenarios and multi-node setups requiring longer cable runs and noise immunity.
What applications and use cases is the TF02-Pro-W best suited for?
The TF02-Pro-W is optimized for level detection in industrial environments, particularly in tanks, silos, and hoppers where robust, long-range single-point ranging is required. Its 7–30 V wide input voltage range, RS-485 industrial interface, and IP5X enclosure rating make it ideal for harsh environments, PLC integration, and distributed sensor networks.
What are the accuracy and precision specifications of the TF02-Pro-W?
The sensor delivers ±6 cm accuracy at 0.1–6 m range and ±1% accuracy at 6–25 m range (both measured with 90% reflectivity targets at 25°C). Repeatability is <2 cm (1σ) across the entire 0.1–25 m range, providing consistent measurements for industrial automation and control applications.
What is the operating temperature range and environmental rating?
The TF02-Pro-W operates between -20°C and +60°C, with a storage temperature range of -30°C to +80°C. It features an IP5X enclosure rating (dust-protected), providing protection against dust ingress and jets of water, suitable for outdoor and semi-protected industrial installations.
What power supply and current draw does the TF02-Pro-W require?
The sensor accepts DC 7–30 V input voltage with a 7:1 voltage tolerance designed for industrial power distribution. Average current consumption is ≤200 mA at 12 V, peak current is 400 mA at 12 V, and total power consumption is ≤4.8 W, making it compatible with standard industrial power supplies and allowing integration into existing systems.
What are the physical dimensions and weight of the TF02-Pro-W?
The TF02-Pro-W measures 85 mm (L) × 59 mm (H) × 43 mm (W) with a compact housing made of PC/ABS material, weighing 92 g including the 1.2 m cable. The compact form factor simplifies mounting on level sensors, pipeline systems, and confined industrial installations.
What are the limitations and scenarios where the TF02-Pro-W should NOT be used?
The TF02-Pro-W has a narrow 3° field of view, making it unsuitable for applications requiring wider coverage or simultaneous multi-point scanning. It is not designed for highly reflective surfaces (mirrors, polished metal >90% reflectivity beyond design specs), fast-moving target tracking, or outdoor direct sunlight scenarios exceeding 100 Klux ambient light without proper hood protection.
How does the TF02-Pro-W compare to competing single-point LiDAR sensors?
The TF02-Pro-W's key industrial advantage is its 7–30 V wide voltage input and native RS-485 interface, versus competitors like Lightware LW series (typically fixed 5–24 V, serial/CAN) and Garmin LidarLite V3 (fixed voltage, SPI/I2C). In the 0.1–25 m range with ±6 cm near-field accuracy, it matches or exceeds the Lightware SF45 single-point specification while offering industrial-grade ruggedness and multi-node scalability.
What platforms and systems integrate with the TF02-Pro-W?
The TF02-Pro-W integrates directly with industrial controllers (PLC, industrial PC) via RS-485, supporting MODBUS RTU and vendor-specific protocols. It is compatible with industrial IoT gateways, SCADA systems, and automation frameworks requiring RS-485 slaves, though it does not natively support Arduino, ROS, or Pixhawk without third-party RS-485-to-serial/USB converters.
