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 the WhisperTrak linear actuator line double force-handling capability from 2 kN to 4 kN; provide higher-speed operation at 2 kN; and offer new options for low-level switching, limit switching and position control at both 2 kN and 4 kN operation.
“We had initially developed the WhisperTrak line for lower-load applications that benefit from a sleek, compact design, such as patient handling, personal mobility and office operations,” said Travis Gilmer, Thomson Product Line Specialist. “When system designers saw the whole package, though, they wanted it for higher-force applications as well. To deliver that, we doubled the available load capacity and bundled in some of the advanced onboard electronics capabilities we have been advancing across all of our product lines. The result is a quiet, intelligent actuator with extremely high power density.”
The 4 kN WhisperTrak offering is rated for 4 kN (900 lb) with load speed at 4 mm/sec (0.16 in./sec). The 2 kN version is rated for 2,000 kN (450 lb) with load speeds of up to 8 mm/sec (0.31 in./sec). All models can be specified for 12- or 24-V input with stroke lengths available between 100 and 500 mm (3.94 to 19.69 in.).
With the recent WhisperTrak expansion, designers can choose from among the following electronics options:
- Five-wire, low-level switching with electronic limit switches for applications that require switching of high-amperage current.
- Two-wire switching with electronic limit switches only, which simplifies wiring and installation for applications that require process start/stop location information but do not require low-level switching.
- Embedded potentiometer and digital encoder with electronic limit switches, which free designers to use position feedback for other purposes.
The new WhisperTrak offerings have the same ruggedness as original Thomson actuators. This includes an IP67 static environmental rating, which provides the ability to operate in harsh conditions in which they are exposed to washdown, rain and dust without the use of an additional cover. All are ETL listed for use on medical devices and conform to medical equipment safety standards AAMISTD-ES60601-1, IEC 60601-1 and CSA CERFTIFIC C22.2 60601. WhisperTrak actuators are maintenance free and have an average life of 10,000 cycles at the maximum load capacity.
