The detector/sensor is integrated with the feeder’s CAN communication network giving immediate reaction to irregularities, but can also be used with stand-alone systems. The virtually contact-free design of the detector ensures that no additional tension is applied to the yarn even when weaving at maximum insertion velocity.

The unit is easily installed and can be used together with all the input and output components in the system.
