Product overviewThe 28BH46PS008IG is a 28 mm integrated stepper servo (NEMA 11) that combines motor, drive and encoder into a single compact body for pulse/direction motion control. The built-in 4096-line (16,384-count) encoder enables closed-loop positioning suitable for compact positioning and assembly equipment.
Key highlights- TTL pulse/direction control
- Input voltage 9–36 VDC; maximum output torque 0.065 N·m
- 4096-line (16,384-count) encoder feedback
- Programmable current and microstepping
- Factory-default filter frequency 400 kHz (software adjustable)
