Frequently Asked Questions
- Is this a safety-rated device?
- No. This sensor is not a safety component. Use it for monitoring and control, not for personnel protection.
- What is the minimum object size it can detect?
- Minimum 30mm x 30mm. For columns, min width is 50mm.
- Can I use this outdoors?
- No. This model is for indoor use only (0 to +40°C). Check LMS100 or LMS500 for outdoor.
- What does “level control” application mean?
- It monitors fill levels in containers. The scanner measures height profiles and outputs switching signals.
- How do I configure the Region of Interest (ROI)?
- Use SICK SOPAS software. ROI can be set from 50mm x 3000mm up to 1000mm x 1750mm.
- What outputs does it provide?
- 4 PNP digital outputs + 1 analog output (4-20mA). Also Ethernet TCP/IP for data telegrams.
Selection Guide
- Choose LMS400-2000 if: you need indoor level control with 3m range and high speed (500Hz).
- For lower speed applications: consider LMS400-1000 (lower frequency, lower cost).
- For outdoor use: select LMS100 or LMS500 (longer range, weatherproof).
- Check your environment: temperature must be 0-40°C. IP65 handles dust and water.
- Interface: Ethernet is standard. RS-232 available for legacy systems.
