Automatic Chaincut

Equipped with photocells, the electronic cutter automatically activates at the beginning and/or end of the seam, ensuring clean finishes with no manual intervention.

Automatic Footlifter

The presser foot is electronically controlled and automatically lifted before and/or after sewing, thanks to integrated photocells—improving efficiency and ease of operation.

Acceleration and Deceleration

Enhanced responsiveness with 14.3% faster reaction time: accelerates from 0 to 5500 RPM in just 100ms and decelerates back to 0 in 180ms for precise and efficient control.

Three Sewing Modes

Choose from three flexible modes:

• Manual: Full control using the pedal.
• Semi-Automatic: Pedal for sewing, with automatic thread trimming and presser foot lift via photocells.
• Automatic: Fully operated by photocells—no pedal required.

Wide Adaptability

The dual-feed system enhances fabric handling, making it easy to sew a wide range of materials with precision and consistency.

Mesh Fabric Mode

Prevents false starts when sewing thin or transparent fabrics like tulle or organza by disabling photocell activation until proper fabric contact is detected—ensuring flawless stitching from the first stitch.

Short Thread Cut

The automatic electric trimmer, triggered by photocells, cuts the thread precisely—8mm at the front and 5mm at the back—minimizing waste and eliminating the need for manual trimming.

Industry 4.0

With the integrated Wi-Fi module, you can monitor productivity and adjust machine parameters remotely via the app.
Note: One Jack gateway is required for every 50 machines.
