Heason Technology has launched a low- cost modular actuator range for pick & place and sample dispensing in life science and other analytical equipment applications. The PLA range features an extruded anodised aluminium housing with a stepper motor driven leadscrew drive and precision recirculating ball linear guide bearings. The range is supplied complete with microstepping drives and a motion controller.
The modular T-slot housing profile allows the use of clamps or nuts to easily assembly multiaxis X-Z, and X-Y-Z positioning systems with a per-axis travel range from 75 mm to 300 mm. The flexible mounting system also provides the possibility to parallel-mount actuators and telescopically extend travel over a range to fulfil Z1 and Z2 axis ‘Syringe’ and ‘Plunger’ requirements - typically found in sample dispensing systems.
The PLA range is designed for medium precision and medium duty use with positioning resolution between 5 and 25 microns using 1 mm to 6.35 mm pitch leadscrews. Positioning repeatability is specified down to 0.025 mm and maximum traversing speeds up to 50mm/sec.
Specifications are based upon open loop motion control with 200 steps/rev hybrid stepper motors and microstepping drives. For higher speeds, increased resolution or improved repeatability, Heason Technology can customise the range using its own in-house design service - adding servo motors, encoders and alternative pitch leadscrews or ballscrews.
