Features of NEXIO S-7300B

DIGIFLEX FEED 2.0
[DIGIFLEX FEED 2.0] newly installed in the S-7300B realizes 8 types of feed control, allowing more detailed settings according to the fabric and the operator's sense. High power mode, allowing for more powerful fabric feeding.

Smooth fabric feeding
Feed dog is directly driven by a stepping motor, so operator feels fabric going very smooth as if it is being sucked in. The previous model, the S7300A, was well-received for reducing operator stress.

Stitch Quality Improvement
Beautiful stitches without puckering, DIGIFLEX FEED 2.0 achieves appropriate thread tightening for the fabric

Reduce Needle Breakage
By controlling the feed motion, optimize the timing of the fabric feed. The fabric can be feed at the right timing to prevent needle breakage even when sewing thick fabrics. The response of the reverse stitch is also faster, reducing needle breakage.

Comfortable Workability
By optimizing the mechanism using our unique analysis technology and adopting a belt drive system,achieved low noise and low vibration. This reduces stress on the operator and allows for comfortable sewing work.
Brother's unique dry technology has made this the first maintenance-free machine in the industry. The needle bar uses [Hybrid DLC], which is more powerful than regular DLC, and the [Special Grease] has made it even more durable.
Motors and electrical components are designed by Brother, suitable for sewing machines. This achieves [low power consumption] and support the needs for environmental friendliness.
Brother utilizes its advanced technical capabilities as a "conglomerate company" to provide highly reliable electrical equipment for not only sewing machines but also printers and machine tools and others. This improves the durability and stability of the products. The high reliability that Brother's technical capabilities bring has been highly praised by many customers.
Comfortable Workability
Digital presser foot lifting (-9xx Spec)
A stepping motor has been adopted for the presser foot lifting mechanism, making it quieter. This reduces stress for the worker and creates a more comfortable working environment. In addition, a digital knee lifting function has been installed, making the knee lifting motion lighter. This significantly reduces the burden on the worker, making them less tired even after long hours of work, helping to improve productivity.
Productivity Improvement by Improving Production Management with IoT
Bird’s nest reduction & Short trimming
The S-7300B also features the short thread remaining function that was well received on the S-7300A. Also features an improved bird’s nest reduction function that makes it easier to use. These thread technologies reduce the amount of thread treatment work after sewing, improving productivity and reducing the burden on workers.
Easy operation User-intuitive Color LCD with Touch Panel Equipped the Color LCD with touch panel and indicates display items with illustration icons, offering user-intuitive operation. For panel display, easy home mode (for operators) and detailed home mode (for supervisor) are available. Each mode is highlighting the necessary and useful functions according to the users so they can grasp the needed information at a glance, switching those modes can be set on the panel.

Detailed home mode (for supervisor)
Detailed settings can be made according to sewing conditions.
Clogging at cross-over seam reduction (Options)
Thickness sensor set SD0637001
Automatic material thickness sensor detects the thickness while sewing, helping to reduce clogging at cross-over seam and needle breakage, S-7300B enables to correct stitch length automatically, when sensor has been detected cross-over seam, offering stable stitch length and high quality sewing for even unskilled-operator.
