Wire tension is one of the most critical parameters of any coil winding process, having an influence on product characteristics, particularly DC resistance of the wire. Wire tension control devices are therefore required to ensure constant wire tension as the wire speed changes during the coil winding process.
The models shown here have a scale calibrated in grams for fast, repeatable setup.
These wire tensioners are very high quality, European made, factory calibrated and will work well with fine wires down to 15 microns at high speed.
Type F71
- Used for fine wire (no larger than 0.08mm at normal recommended wire tension)
- Arm position gives feedback to the system, adjusting the main friction wheel to regulate and maintain constant wire tension during the coil winding cycle.
- The tension setting is controlled by adjusting the lower knob, to ensure that the arm operates within its working limits.
- Polished ceramic parts at each point of contact protect insulation and guide the wire.
- Captive roller on tension arm is easy to thread, eliminates chance of losing wire.
- Tension can be set using scale in grams 1.5gr - 50gr (~0.01mm-0.08mm)
Type M65
- Used for fine wire (no larger than 0.23mm at normal recommended wire tension)
- Arm position gives feedback to the system, adjusting the main friction wheel to regulate and maintain
constant wire tension during the coil winding cycle.
- The tension setting is controlled by adjusting the lower knob, to ensure that the arm operates within its working limits.
- Polished ceramic parts at each point of contact protect insulation and guide the wire.
- Captive roller on tension arm is easy to thread, eliminates chance of losing wire.
- Tension can be set using scale in grams 15gr - 350gr (~0.04mm-0.23mm)
Type DMA300
- Used for fine wire (no larger than 0.23mm at normal recommended wire tension)
- Arm position gives feedback to the system, adjusting the main friction wheel to regulate and maintain constant wire tension during the coil winding cycle.
- The tension setting is controlled by adjusting the lower knob, to ensure that the arm operates within its working limits.
- Polished ceramic parts at each point of contact protect insulation and guide the wire.
- Captive roller on tension arm is easy to thread, eliminates chance of losing wire.
- Regulates at high wire speed up to 25M/s
- Tension can be set using scale in grams 33gr - 350gr (~0.06mm-0.23mm)
