Warner Linear, a global leader in the design and manufacture of electric
actuators and controls, recently introduced the programmable S-Track
actuator for general duty applications including conveyor diverter arms, light
commercial and industrial, medical, turf & garden and recreational vehicles.
The innovative S-Track actuator is available with a mounted membrane
keypad which allows users to change both end limit stop locations and
program two additional stops if needed. Some competitive actuators
offer programmable stop positions which require the customer to plug in
a separate hand held control. Warner Linear is the only manufacturer to
provide adjustable control integrated into the actuator.
The S-Track also has an integral MP150 Metri-Pack 8-pin molded
connector that allows for several standard input and output features to
monitor the operation of the actuator. The current and temperature of the
motor are monitored at all times and power is removed from the motor
when limits are exceeded to protect components from failure.
MEETING THE FLEXIBILITY CHALLENGE
A large packaged food manufacturer needed reliable linear
actuators that could quickly reset conveyor system diverter arm positions
based on frequent carton size changes. Previous actuators required
lengthy set up times to reset diverter arm opening widths and stops, which
negatively impacted productivity.
Warner Linear Programmable S-Track actuators were
chosen to meet the requirements of this fast-paced, high change over
production application. The easy-to-use,
integrated keypad allowed operators to set and reset
end of travel positions, as well as two intermediate stops,
in response to changing carton sizes. Feedback range
automatically adjusts to new end position settings.
Enhanced control allows for 12 or 24 VDC switched power
operation of the S-Track actuator by turning power off to
the motor automatically when the internal end limits are
S-Track actuators feature a <56dB noise level, 400 lb.
max. dynamic and 700 lb. static load ratings, 0.25"/sec.
(1" /sec. no load) speed rating, and a 16" max. stroke
length with end-of-stroke limits. Models are available with
aluminum or engineered plastic housings.
An array of actuator controls is also available from simple-to-use switch box controls for basic extend/retract function
to state-of-the-art microprocessor-based digital electronic
controls using SMT design and manufacturing processes.
