11/24/2011 | Thomson Introduces Quiet, Strong and Compact WhisperTrak™ Linear Actuators

KRISTIANSTAD, SWEDEN –Thomson Industries introduces the new Thomson WhisperTrak™ Electric Linear Actuator line. Featuring quiet (<45 dBa), maintenance-free operation in a compact one-piece housing, the Thomson WhisperTrak linear actuator maximises design flexibility and improves performance and user comfort in personal mobility, rehabilitation, and medical equipment applications where reliability, small size and low noise are primary design considerations. These attributes also make the Thomson WhisperTrak actuator an ideal solution in office, domestic-use equipment and also low-duty industrial applications. Thomson WhisperTrak actuators comply with CE and UL certificates and are built in accordance with ISO 9000.

Its completely sealed, IP67 enclosure enables the WhisperTrak electric linear actuator to provide true maintenance-free operation throughout the entire life of the actuator, even with regular exposure to washdown, rain, dust or other particulates. In these conditions, the WhisperTrak actuator is rated to provide a minimum of 10,000 cycles, defined as one full stroke back and forth, at maximum load. Reducing the stroke and/or the load will naturally increase operating life.

“Rooted in more than 40 years of Thomson Linear Actuator pedigree and supported by a global manufacturing, sales and service organisation, the WhisperTrak actuator is engineered to deliver long life and zero-maintenance operation, with virtually inaudible actuation, within one of the most compact envelopes available today,” says Håkan Persson, Thomson Product Line Manager for Linear Actuators. “The WhisperTrak actuator is also pin-to-pin compatible with most competitive actuators in this market segment. This enables OEMs to easily replace an existing actuator with a smaller, lighter and quieter option that will reduce total cost of ownership and improve their competitive advantage.”

Thomson WhisperTrak electric linear actuators are available off-the-shelf with optional electronic limit switches (ELS), anti-rotation and position feedback options. These options do not increase the housing size, but fit within the compact envelope of the standard WhisperTrak model.

Thomson WhisperTrak actuators operate at 12 or 24 VDC, and are rated to handle static and dynamic loads up to 2000 N (450 lbs.) at speeds up to 5.8 mm/s (0.23 in/s). They are available with standard stroke lengths of 10, 20, 30, 40 and 50 cm; custom stroke lengths are available.
