The 42STH34M20X01 is a high-precision hybrid stepper motor with a 0.9° step angle and 400 steps per revolution, designed for applications requiring fine motion control. It features a 42 mm frame size, ball bearings, and a holding torque of at least 190 mNm. The motor has a rated current of 2.00 A per phase (2-phase ON), a phase resistance of 0.9 Ω, and an inductance of 1.4 mH. It operates within an ambient temperature range of -20 to +50 °C, with a maximum coil temperature of 130 °C (Class B insulation). The rotor inertia is 38 g·cm², and it supports a maximum radial force of 28 N at 20 mm from the flange and a maximum axial force of 10 N. The motor weighs 230 g and uses AWG24 UL1007 leadwires. Its dielectric strength is 500 VDC for one minute, with an insulation resistance of 100 MΩ at 500 VDC.

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.
