- OEM sensor integration
Why choose this series: If your system requires millimeter-level accuracy in a very limited space, these modules offer the best balance of size, precision, and cost.
2.2 Medium & Long Range Phase Modules
Typical specs:
- Range: up to 150–200 m
- Accuracy: ±(3 mm + D×1/10000)
- Higher power and larger optics
Best suited for:
- Industrial measurement systems
- Construction and structural monitoring
- Outdoor fixed installations
Selection tip: Choose these models when range is more important than compact size, but you still need high repeatability.
2.3 Red vs Green Laser Phase Sensors
| Lazer Tipi | Avantajlar | Recommended Scenarios |
|---|
| Red (610–690 nm) | Lower power consumption, cost-effective | Indoor, controlled lighting |
| Green (510–550 nm) | Better visibility, less ambient light interference | Outdoor, liquid level, reflective surfaces |
Special note: Green laser phase sensors perform better on liquids and complex surfaces, making them ideal for water level and outdoor industrial applications.
2.4 High-Frequency Phase Modules (LDJU Series)
Key highlight: measurement frequency up to 10,000 Hz
Best suited for:
- High-speed motion tracking
- Dynamic object tespit
- Real-time feedback control systems
If your application values speed over range, this series is unmatched.
When to choose housing versions:
- Dusty or humid environments
- Outdoor installations
- Harsh industrial sites
Metal housing improves mechanical stability, EMC resistance, and service life.
3. Pulse Laser Rangefinder Series: How to Choose
3.1 Mini Long-Range Modules (TS1224 Series)
Typical specs:
- Range: up to 2000 m
- Size: coin-sized metal housing

- UAVs & dronlar
- Portable surveying devices
- Space-constrained long-range systems
3.2 Square & Cylindrical Rangefinder Modules
Square (PTFS):
- Easier system integration
- Higher frequency options (up to 500 Hz)
Cylindrical (TC25):
- Optimized for drone and optik systems
- Lightweight design
3.3 Telescope Rangefinder Sensors
Key advantage:
- Integrated optical viewfinder

FAQ: Laser Distance Sensor Selection
What is the difference between phase and pulse laser distance sensors?
Phase (iToF) lazer mesafe sensörleri calculate distance by measuring phase differences in a modulated laser signal. They offer higher accuracy (millimeter-level) and faster update rates, making them ideal for industrial automation and continuous measurement. Pulse (dToF) sensors measure the uçuş süresi of laser pulses and are better suited for long-range and outdoor applications, typically with meter-level accuracy.
How do I approach laser distance sensor selection for industrial applications?
Start by defining your required measurement range, accuracy, and environment. Indoor, short-to-medium range applications usually benefit from phase lazer sensörleri, while outdoor or long-distance projects require pulse laser rangefinders. Also consider target surface, installation space, and communication interface requirements.
When should I use a green laser instead of a red laser?
Green laser distance sensors (510–550 nm) are more visible to the human eye and less affected by ambient light. They perform better on reflective surfaces and liquids, making them ideal for outdoor measurement and liquid level monitoring. Red lasers are more energy-efficient and cost-effective for indoor use.
Are laser distance sensors suitable for liquid level measurement?
Yes. Phase-based laser distance sensors, especially green laser models, can penetrate liquid surfaces more reliably and provide stable measurements for non-contact liquid level monitoring in industrial environments.
What communication interfaces do Meskernel laser distance sensors support?
Most Meskernel laser distance sensors support UART, RS232, and RS485 interfaces. Some models also support Modbus and high-baud-rate communication, making them easy to integrate into industrial control systems, PLCs, and embedded platforms.
