Sick WLG4S-3P3434 Description
- Continuous adaptation of the switching threshold when there is soiling
- Temperature compensation for stable working point
- Small, highly visible, sharply defined light spot
- Detection of glass with damping > 8%
- Teach-in function for fast and simple commissioning
- The all-around carefree package provides "best-in-glass" performance since all known transparent objects can be reliably detected
- Less downtime due to reliability of usage under changing environmental conditions - temperature, dust and drift effects are continually compensated by the adapting switching threshold.
- Simple and fast setting with a single press of the teach-in button
