Thomson Electrak Pro Actuators
Date: 01 May 2010
Thomson Elektrak Pro series push-rod style linear actuators are now available from West Sussex based motion specialist Heason Technology Limited.
Characterised by its extreme durability,
toughness and compactness, the DC motor driven Electrak Pro is
available in Acme leadscrew or ballscrew versions with a broad
range of options making it equally suited for simple open loop load
actuation or sophisticated closed loop control.
The CE certified Electrak Pro series is supplied in choice of 12 or
24 VDC input as standard or optional 36 VDC, allowing flexibility
for battery or DC power supply operation. The actuator's maximum
stroke length is 300 mm with a dynamic load rating of 2000N for the
ballscrew version and 750N for the lead screw option. With no-load
speeds to 50 mm/sec and a 25 percent full load duty cycle, the
Electrak Pro's performance will meet the requirements for a wide
range of actuator applications for industry, agriculture,
construction, medical, H & V and many more.
An attractive 'clam shell' cast aluminium housing with a stainless
steel extension shaft and support tube combine for a smart design
for applications where the actuator is externally mounted such as
medical or laboratory lift equipment. The Electrak Pro is rated for
IP66 operation with an optional IP67 version for liquid immersion
protection. The housing and its integral electrical connector are
fully gasket sealed and together with an operating temperature
range of -40ºC to +85°C, the actuator is well suited for use in
hostile indoor and outdoor environments where washdown and spray is
frequent. The compact size of the actuator allows installation in
restricted spaces with an unextended length of around 250 mm for
the leadscrew version.
As standard, electronic limit switches are fitted for over-travel
protection and a load holding brake is included for the ballscew
version. Further standard options include an electronic load
monitor that checks critical parameters and shuts down the actuator
if they are exceeded. The front and rear clevis mounting is
straightforward for installation and removal, and in the event of
power failure, an integral manual override is easily accessed with
a 5 mm Allen key for fast hand-operated position adjustment.
To suit the widest range of applications, the Electrak Pro series
is available with a number of options and accessories. These
include position feedback from a choice of optical encoder or a
potentiometer which can also be used as a part of a signal follower
option that allows the actuator to track position from a customer
provided analogue input. A programmable limit switch option is
available to modify the usable stroke length via a hand held
pendant which may be removed after set-up to prevent unauthorised
changes.
In addition, a PWM speed control option interfaces load monitoring
system with a customer supplied PWM input for variable speed
control. The actuator can also be supplied in a protective black
paint finish if required.
As a Premier Partner distributor for Thomson, Heason Technology can
also supply fully customised versions of the Electrak Pro together
with controls as complete system solutions.
The Premier Partner programme aims to ensure a high level of
service and support with regular training, competitive pricing and
recommended inventory levels for all participating distribution
partners. Heason Technology's in-house design capability matches
products from its distribution partners with its own expertise in
motion control and automation to provide customised
electro-mechanical solutions for challenging applications across,
