var overview='<h4>Linear Belt Slider</h4><p>Complete  ready-to-run Belt Slider assembly for testing and measuring, cameras, antennas,  automatic assembly and positioning. Linear belt sliders supports loads up to 25 pounds for moving, and a maximum weight of 100 pounds before damage occurs.  They give you smooth and rapid linear motion with essentially zero backlash. Belt Slider length is given as travel in inches, add the  carriage length to obtain total rail length. 6 inches of travel with 4 inch carriage shown in picture.</p><p>Key  features are .0015 inch resolution, 16 in/sec speed, and over 10 million inches  travel life. Versatile use, fits in tight spaces, and is easy to mount  due to the thinness of rail -- size is 84mm total width x 5.5 mm thick base,  and 14mm maximum rail thickness. Unlike competitors sliders, these give you 100% full travel--the carriage moves end to end of the aluminum rail. The  Excitron motor controller gives you many modes of operation for automatic or  computer driven motion, please see details in Au Controllercoders category.</p><p>Includes:</p><ul>  <li>Au57-40M controller and stepper motor is standard with 800 half-steps per revolution</li>  <li><a href="http://www.excitron.com/webdocs/Items/Details359.cfm">24 volt 80 watt universal power supply</a> with AC power cord</li>  <li>RS232 serial interface built-in</li>  <li>Universal mount carriage 3.15 inches wide x 6 inches long</li>  <li>Long life timing belt components, MXL .040 inch pitch</li>  <li>Four precision low friction (.06 coefficient) guide bearings,  which are impervious to dust and debris</li>  <li>Dual physical end stops, causes no harm to run into them</li></ul><p>Nothing  else is needed. Belt Slider in picture has 6 inches of travel; available up to120  inches travel.  Options are:</p><ul>  <li><a href="http://www.excitron.com/webdocs/Items/Details408.cfm">14 inch carriage</a> for extra rigidity and stiffness</li>  <li>For more torque, upgrade to our  Au60-45, Au60-86, Au86-65, Au86-80, or Au86-118 integrated motor/controller. The additional price is equal to the Au motor price difference from the Au57-40M, and you order/pay for this motor upgrade by selecting Custom hardware or firmware and make the quantity equal the dollars needed.</li>  <li>Optical encoder for position feedback, coming soon as a built-in encoder inside the Au controller.</li>  <li>Optical photosensors for Home or limit position feedback.</li> <li>High-life high-flex cables and cable track guides, <a href="http://www.excitron.com/index.cfm?Action=ViewContact">contact us</a></li></ul>';
