Intelligent Fabric Adaptive System
The Octopus chip instantly detects changes in the fabric during sewing, calculating optimal parameters in real-time. The powerful Ape motor ensures precise needle penetration and fabric feeding, enabling smooth, continuous sewing across all fabric types.
Extended Machine Arm
The enlarged workspace allows you to work with larger materials, the distance from the needle to the machine body is 30.5 cm.
Octopus AI Dual-Core Chip
The Octopus AI dual-core chip intelligently detects and responds to changes in material thickness in real time, optimizing machine performance for stable and precise sewing.
Vigorous Ape Powerful Motor
Provides 4 times faster motor response with a peak torque of 11.3 Nm and 22.5% higher specific power. High torque and improved motor dynamics provide greater braking force and stable operation.
Jack A5E-B-H-7 AMH is a single-needle lockstitch sewing machine with an intelligent fabric adaptation system.
Jack A5E-B is a single-needle lockstitch sewing machine with automatic functions, lower fabric feed, and an energy-efficient direct-drive motor. The extended design provides a 30.5 cm clearance from the needle to the machine body. A stepping motor controls the stitch length and backtack stitching, while the Octopus AI dual-core chip adjusts machine settings in real time based on fabric thickness. Increased torque ensures smooth thread passage through multi-layer materials. Features include a thread trimmer leaving tails up to 3.5 mm, three function buttons next to the needle bar (half stitch, add stitch, backtack), and a USB port for connecting external devices.
