The 42STH34M05X01 is a high-precision 42 mm hybrid stepper motor with a 0.9° step angle and 400 steps per revolution, designed for applications requiring fine motion control. It has a holding torque of at least 190 mNm and a rotor inertia of 38 g·cm². Electrical specifications include a phase resistance of 13.5 Ω and a phase inductance of 24.5 mH, with a rated current of 0.50 A per phase for two-phase operation. The motor features ball bearings, a maximum coil temperature of 130 °C (Class B), and operates within an ambient temperature range of -20 °C to +50 °C. It weighs 230 g and uses AWG24 UL1007 leadwires. Maximum radial and axial forces are 28 N and 10 N, respectively. Insulation resistance is 100 MΩ at 500 VDC, with a dielectric strength of 500 VDC for one minute.

The 42STH34-High Precision is a 2 phases 0.9° hybrid stepper motor. This high resolution stepper motor has half the step angle of standard stepper motors. The high precision type increases motor resolution from 200 steps/revolution to 400 steps/revolution. Smaller step angles can be achieved by half-step driving or microstep driving. If the pulse speed is within resonance region, vibration may increase. The stopping accuracy improves as the torque increases while minimizing the negative effect of the frictional load. Resonance regions can be avoided by switching to a 0.9° high-resolution type stepper motor.
