Product OverviewThe SDLM-051-070-01-01 is a compact high-force direct drive linear servo actuator with a 0.500-inch stroke. Its housing measures 2.000 in. (50.8 mm) in diameter and 2.750 in. (69.9 mm) long. The actuator provides a 0.500 in. (12.7 mm) stroke, 6.8 lb (30.3 N) of continuous force, and 21.5 lb (95.7 N) of intermittent force at a 10% duty cycle.Performance and ConstructionThe non-commutated direct-drive design eliminates ball screws, gears, belts, and other mechanical transmission components. Direct coupling to the low-inertia output shaft provides zero mechanical backlash, no cogging, high acceleration and deceleration, smooth bidirectional motion, quiet operation, and long service life.Integrated Encoder and Temperature SensorThe integrated quadrature optical encoder with differential outputs is protected inside the actuator housing and directly coupled to the output shaft. It provides 1.25 microns resolution for closed-loop position and velocity control. Final system accuracy and repeatability also depend on the controller, mechanical installation, load, structural stiffness, and servo tuning. The integrated temperature sensor provides thermal feedback that can be used to maximize throughput while keeping the actuator within its operating limits.Key Features• 0.500 in. (12.7 mm) linear stroke• 6.8 lb (30.3 N) continuous force • 21.5 lb (95.7 N) intermittent force at 10% duty cycle • Integrated quadrature optical encoder with differential outputs • Non-rotating 0.250 in. (6.4 mm) output shaft with plain linear bearings • Direct-drive operation with zero mechanical backlash and no cogging • High acceleration, rapid reversal, quiet operation, and long service life • Integrated temperature sensor for thermal monitoring ApplicationsManufacturing and Automation: Assembly, inspection, sorting, packaging, shaking, and automated material handling.Medical and Semiconductor: Medical devices, procedure tables, instruments, and semiconductor handling. Positioning and Actuation: Antenna positioning, dampers, door and valve actuators, agricultural equipment, and adjustable furniture. Mechanical Integration and ControlEach housing end has two 10-32 UNF-2B mounting holes on a 1.000 in. (25.4 mm) bolt circle. Each shaft end has a 6-32 UNC-2B threaded hole. For closed-loop operation, use a compatible servo controller and current amplifier selected for the required force, speed, duty cycle, load, and motion profile. |
