January 24, 201 - Heason announces Dover Motion DDM X-Y table.The open frame X-Y positioning stage has performance and accuracy that will suit demanding high throughput automation applications for imaging and biotechnology. The low profile DDM features direct drive ironless linear servomotors and anti-creep cross roller bearings for exceptionally smooth zero-backlash motion combined with integral linear encoders that provide positioning resolution to 0.1 micron (to 5 nanometres on request).
The small footprint DDM stage has a nominal travel of 120 mm x 80 mm and an overall height of only 40 mm - with a generous through aperture that will suit both imaging and microscopy use as well supporting microtitres or wellplates with top and underside access for biomedical sampling use. The DDM is designed to provide imaging throughput of up to 30 images/sec with outstanding stability during image capture.
The DDM series has built-in cable management with a single point exit for all motor and encoder connections which reduces the overall stage footprint and facilitates straightforward installation. The combination of direct drive servomotors and non-contact optical encoders plus the absence of moving cables provides the basis for exceptionally long working life with minimal maintenance.
