The HS-A1 Series compact, 4-axis SCARA robots offer the highest speed and repeatability in their class. Although these small industrial robots have a compact, space-saving design, they have a large load-handling capability, with a maximum payload of 5 kg. In addition, their large, 0.1 kgm2 maximum allowable moment of inertia enables a wide range of end effectors and applications. All HS-A1 Series robots are available in dust- and mist-proof (IP65) or ISO 4 (class 10) cleanroom configurations. ANSI and CE compliance allows global deployment. UL-listed models are available for both the U.S. and Canada.
