Sensor module 16564 Series

Eltex yarn sensor 16560-67, 16580 with opto coupler output General description The yarn break sensors are working on the piezoelectrical principle. The yarn movement is transferred into an electric signal, which is amplified and evaluated within the sensor. The sensor has an opto coupler output. A LED (light emitting diode) indicates the yarn movement Function and description Sensing part: ceramic eyelet/bar Power supply: 24 VDC (16–33 VDC) Current consumption: 25 mA Output: opto coupler Sensitivity setting: with a potentiometer on the sensor. The movement of the yarn is best detected if the yarn angle is 10–15° through the eyelet. To set the sensitivity, turn the potentiometer clockwise to the end position (maximum sensitivity). Let the machine run while turning the potentiometer slowly counterclockwise until the sensor stops the machine even though the yarn is moving correctly. Then turn the potentiometer approximately 45° clockwise. If there are still false stops, increase the setting by another 20° clockwise.
