Thomson WhisperTrak Linear Actuators

Thomson Industries Inc. has expanded its WhisperTrak actuator line to give motion system designers greater ability to extend quiet, compact actuation to more demanding applications.

• New additions to lineup double force-handling capability from 2-4 kN
• Provides higher-speed operation at 2 kN
• Offers new options for low-level switching, limit switching and position control at both 2 and 4 kN operation
• Rated for 4 kN (900 lbs.) with load speed at 4 mm/sec (0.16 in./sec)
• 2 kN version is rated for 2,000 kN (450 lbs.) with load speeds of up to 8 mm/s (0.31 in./sec)
• All models can be specified for 12- or 24V input with stroke lengths available between 100 and 500 mm (3.94-19.69 in.)
• Options include five-wire, low-level switching with electronic limit switches for applications that require switching of high-amperage current
• Electronic limit switching (ELS) automatically cuts power to the actuator when preset threshold is reached, aiding both control precision and safety
• Low-level switching can be valuable for wiring high-current draw loads into programmable logic controller or small battery
• Two-wire switching with electronic limit switches only available as an option, which simplifies wiring and installation for applications requiring process start/stop location information but not low-level switching
• Embedded potentiometer and digital encoder with electronic limit switches model options free designers to use position feedback for other purposes
• Embedded ELS gives designers more control flexibility for lower loads or for applications not using low-amperage controls
• Embedding ELS into firmware retains end-of-stroke protection without need for additional programming and configuration, enabling users to run operation up to end of stroke without worrying about damaging actuator or control configuration
• Features compact and easy-to-use design that complements aesthetics of factory equipment
• Includes IP67 static environmental rating
• Maintenance free and features average life of 10,000 cycles at maximum load capacity
