Product features
World-Class Sewing Speed of Up to 2,800 Stitches Per Minute with Exceptional Stitch Quality Equipped with the DIGIFLEX TUNE function, which digitizes traditional adjustment settings for faster, more precise tuning. Features upper thread tension sensing, skipped stitch detection, thread breakage detection, and thread tension monitoring for enhanced sewing quality control. An adjustment monitoring function continuously tracks sewing conditions, helping operators accurately detect defects and maintain consistent seam quality.
Features of NEXIO BAS-342K

Sensing makes it clear how to handle sewing defects, minimizes downtime and increases productivity.
The adjustment time of the sewing machine due to poor sewing is greatly reduced by sensor monitoring technology. Appropriate adjustments depending on the cause of the sewing defect can be made just from checking numerical values on the panel.

Digitalized analog adjustment to achieve precise adjustments.
Adjustments in increments of 0.01 millimeters are possible, eliminating variations in adjustments due to people and environments. The sewing machine adjustment, which was done visually or manually, will change to adjusting while checking the target value set on the panel and current value.

Prevention of skip stitch and thread slippage at sewing start *Patent applied
Skip stitch and thread slippage at sewing start can be prevented by holding the upper thread with the intermittent presser foot.

The Upper thred tension sensou ,skip stitch detection,thread breakage delection,thread tension monitoring.
By using the upper thread tension sensor to detect skipped stitches, thread breakage, and monitor dynamic tension, sewing defects can be detected and defective products are prevented from moving on to the next process. By detecting sewing defects by detecting skipped stitch, thread breakage detection, and dynamic upper thread tension monitoring, defective products are prevented from flowing to the downstream process. By continuously monitoring the tension, we plan to add additional criteria for detecting other defects and abnormalities.
Stable sewing quality,improved anomaly detection function Brother's innovative digital technology enables analog adjustments to be accurate to 0.01 millimeters. Supports stable production by maintaining high production efficiency and quality.
Productivity
Sensing makes it clear how to handle sewing defects, minimizes downtime and increases productivity.
Comfortable Workability
The digital adjustment method using sensing makes it easy to adjust the needle bar height position, hook timing, needle guard gap, needle clearance, while checking the numerical values on the panel.
Preventing machine breakdown
Oil level monitoring
By alerting you when the oil level is low, you can prevent machine damage due to operation without oil.
Upper thread tension monitoring
Skipped stitch detector
By detecting sewing defects by detecting skipped stitch, thread breakage detection, and dynamic upper thread tension monitoring, defective products are prevented from flowing to the downstream process.
Fabric thickness detection
By measuring the thickness of the fabric at the beginning of sewing and determining whether it is within the specified value, misplacements are detected before they occur. If it differs from the set value, an error will be displayed on the LCD screen.
Other features
Prevention of skip stitch and thread slippage at sewing start *Patent applied
Skip stitch and thread slippage at sewing start can be prevented by holding the upper thread with the intermittent presser foot.
Sewing examples
Airbags
Stable sewing quality is achieved even for small parts such as front airbags and curtain airbag Y-socks and tabs.
