Stepper motors of ZK42HS series

Hybrid stepper motors of ZK42HS series are used in textile industry (winding machines, flat knitting machines), medical equipment (syringe and infusion pumps, dental equipment), video surveillance and signaling devices, laser systems. Also can be used in production automation (printed circuit boards, soldering of the semiconductors). Characterized by a high output torque, high resolution, high-precision installation at the desired position, low vibration level.
