Although this sensor is a reflection non-contact sensor developed for take-up winders, it can also be used for many machines such as drawing machine.
Features:
- The structure is simple even for multi-spindle because this sensor is reflection type.
- This sensor hardly malfunctions due to vibration or impact.
- This sensor can detect only moving yarn because it employs differential method using 2 light-sensitive elements and this cancels unnecessary reflected light.
- Because the light-emitting and light-sensitive elements are exposed and they have a shape of convex lens, oil solution, etc. are hardly accumulated on them and they can be cleaned easily.
- All the vibrating yarns can be detected because the light is emitted continuously
