Key FS-N40 series features
Why the FS-N40 series is easier to set up and holds calibration longer:
- New high-intensity LED module with parabolic reflector - higher coupling efficiency and stronger light output for maximum detection differential
- TERA power switch - one-key changeover between standard and high power for dirty environments and low-reflectivity targets
- Full-text multilingual OLED display (not 7-segment) - plain-text menus including Chinese, faster setup with fewer manual lookups
- ACT-R button with optical filter - automatic receive-light monitoring and easy threshold tuning
- Beam-alignment indication - fiber-tip indicator lights green when the optical axis is aligned, so one person can finish alignment
Typical applications
- Micro part detection, high- and low-reflectivity targets, electronics counting, precision assembly, continuous detection in dusty or oily environments
