Danaher Linear has long been the leader in ball bearing screws and linear actuators. This new line of Electrak programmable linear actuators offers an expanded range of performance in life, load carrying capability, speed, duty cycle, accuracy and programmability. The ball screw actuators are rated for continuous duty and now can operate at speeds up to 25 inches per second or position loads up to 2000 pounds with repeatability of 0.0005". They are designed to operate up to 50 million cycles.
Precise Linear Positioning Applications Electrak 2000 actuator systems are designed to provide efficient linear motion control for applications requiring: • • • • • • programmability wide speed range (up to 25 in/sec) high load capability (up to 2000 lb) high duty cycle rate (up to 100%) maintenance free operation long life (up to 50 million cycles) These Electrak 2000 actuators are both providing indexing functions.
This Electrak 2000 actuator is positioning valves inside an enclosure. The application is typical of positioning gates, valves, dampers or chutes. This application shows the Electrak 2000 actuator positioning the heating head that is used in sealing plastic bags. Positioning and timing are critical to seal the bag and to avoid burning through it. This could be typical of applications that require positioning tooling work heads, cutters or drills.

Controls For BP93, BI12 Actuators SS2000I Programmable Motion Control The SS2000 control consists of a SS2000I indexer and SS2000D6 6 amp drive. The SS2000I indexer includes the MS2000 programming software and an RS232 cable. The SS2000D6 includes a 10 foot motor power cable. Both the indexer and drive must be ordered to operate an Electrak 2000 actuator. Plug In Closed Loop Module With Memory Board This module can be added to any SS2000I control to convert it into a Closed Loop unit.
Motion Profiles Triangular Motion Profile In this motion profile the actuator is linearly accelerated and decelerated to provide the desired incremental move time. All of the movement is either in acceleration or deceleration with no steady run speed.

To order an Electrak 2000 as a complete system with or without options specify the following information: 1.
Glossary Acceleration Cantilevered mount Extension rate The change in velocity as a function of time. A mount where the actuator is not supported on both sides. Cantilevered mounts are not recommended. The speed at which the actuator extends or retracts. The extension speed is load dependent and the actuator must not be programmed to exceed the load/speed curve. Axial lash/backlash The axial free motion between the ball nut and screw without rotation between the two components.
Limit switch Pulse rate Resolution A switch used to limit motion or travel in a particular direction. The frequency of step pulses applied to a step motor. The pulse rate multiplied by the resolution of the motor yields the rotational speed of the motor in revolutions per second. The rotations per second multiplied by the lead of the screw and divided by the gear ratio provides the extension speed in inches per second. The smallest positioning increment that can be achieved.
