Warner Linear (Belvidere, IL) has introduced the S-Track line of linear actuators for generalduty applications. Models are available with aluminum or engineered plastic housings. Enhanced control allows for 12 or 24 VDC switched power operation by turning power off to the motor automatically when the internal end limits are reached. An integral MP150 Metri-Pack 8-pin molded connector allows several standard input and output features to monitor the operation of the actuator (including motor thermal and current overload protection). The actuators feature a <56 dB noise level, 700-lb. maximum dynamic and static load rating, 0.25"/sec. (1" no load) speed rating, and a 16" maximum stroke length with end-of-stroke limits. A variety of actuator controls is available, from switch box controls for basic extend/retract function, to microprocessor-based digital electronic controls using SMT design and manufacturing processes.
