Housing Outside Diameter, 1.000 inch, 25.4 mm

Product Overview The SDLM-025-095-01-01 is a compact one-inch-stroke direct drive linear servo motor with integrated high-resolution position feedback. Its housing measures 1.000 in. (25.4 mm) in diameter and 3.750 in. (95.3 mm) long. The actuator provides a 1.000 in. (25.4 mm) stroke, 21.0 oz (5.8 N) of continuous force, and 66.4 oz (18.5 N) of intermittent force at a 10% duty cycle. Performance and Construction The 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 The integrated quadrature optical encoder 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. Key Features • 1.000 in. (25.4 mm) linear stroke • 21.0 oz (5.8 N) continuous force • 66.4 oz (18.5 N) intermittent force at 10% duty cycle • Integrated quadrature optical encoder • Non-rotating 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 Applications Manufacturing and Inspection: Precision assembly, inspection, scanning, sampling, and automated handling. Medical and Semiconductor: Medical procedure equipment, semiconductor handling, and laboratory automation. Optical and Mechanical Systems: Laser machining, antenna positioning, dampers, door and valve actuators, and agricultural equipment. Mechanical Integration and Control Pre-drilled mounting features and threaded shaft ends make the actuator straightforward to couple directly to a load or positioning stage. For closed-loop operation, use a compatible servo controller and current amplifier selected for the required force, speed, duty cycle, load, and motion profile.
