Whispertrak Linear Actuators

Thomson WhisperTrak models are the quietest additions to our well-known electric linear actuator family. This actuator range sets a standard for medical, personal mobility, material handling, marine and structural automation applications. It is small, quiet, washdown-proof and created from the accumulated knowledge that Thomson has gathered from being the actuator industry leader for more than 50 years.

Compliances IEC 60601-1, CSA C22.2, AAMI ES60601-1 (3)
Options
  • Electronic limit switches (ELS) (4)
  • ELS + low level switching (1) (5)
  • Analog or digital position feedback, with or without ELS
  • Mounting adapters turned 90°

​           1) Thrust is reduced at lower temperatures for 2000 N (450 lbs) high speed (54A) and 4000 N (900 lbs) units with ELS + low level switching (option E).
           2) Prevents the extension tube from rotating if it is not fixed in the end.
           3) 4 kN units greater than 30 cm of stroke are not ETL recognized. ETL certification available on N, E, P and D feedback options only.
           4) Shuts off power at the end of stroke and all along the stroke at overload conditions. ELS is normally set for 120% of the rated dynamic maximum load.
           5) Low level switching allows low level signals to control the actuator movement instead of having to switch the high amperage motor voltage.
Whispertrak Feature Highlights:
  • Exceptionally quiet, boasting a low sound level of less than 45 dBa
  • Compact and compatible, making it easy to swap into existing applications
  • Zero maintenance throughout its entire life (10,000 cycles avg. at maximum load)
  • Ultrasonic welding of enclosure provides high degree of sealing
  • Washdown proof during operation and can be submerged when not operating
  • Anti-rotation mechanism
  • IP67 environmental protection class
  • IEC 60601-1, CSA C22.2, AAMI ES60601-1 compliant
Whispertrak Option Highlights:
  • Electronic limit switches – shuts off power for overload conditions during and at end of stroke
  • Anti-rotation mechanism – prevents the extension tube from rotating if it is not fixed on the end
  • Analog or digital position feedback
  • Mounting adapters turned 90° 
  • DCG Actuator Controls (DCG 152/154, DCG 252/254)
  • Variety of cable and connection types (flying leads, phono, DIN, Pac Con)
Whispertrak Best-fit Applications:
  • Patient handling equipment that requires lightweight, quiet design, including wheel chairs, patient lifts and other rehabilitation devices
  • Material handling equipment that benefits from compact, easy-to- use and aesthetically complementary actuators
  • Structural automation in both commercial and residential buildings that require robust and powerful, yet quiet, actuation, including louvers, adjustable desks, beds, reclining chairs and hideaway TVs
  • Marine devices, including boats, in which water spray is prevalent
