Coiltek’s CS-5100 is a repackaging of the reliable and accurate ultrasonic sensing electronics of the workhorse CS-5000 series control. Configured as a sensing head connected to a control housing, this version of the non-contact loop control must be mounted on an existing framework. Like the CS-5000, it is tailored for the specific purpose of slack loop control. By sensing the height of the stock, the CS-5100 controls the replenishment of the loop by the feed device (straightener, decoiler, puller, etc.). Set up in ‘take-up’ mode, it can also control a downstream device, such as a rewind stand.


  • Super-easy Setup: Takes mere seconds. Push-button set-up or via USB with computer.
  • Works with many different types of materials: Metals, Plastic Extrusions, Rubber, Mesh products, Fabric, etc.
  • Simple two screw mounting to existing stand or framework.
  • Flexible: May be used very close to the sensor with control ranges from 5 inches (125mm) to 70 inches.
  • Using free CSWin software, the control range may be as small as 1 inch and as large as 200 inches.
  • Useful feature set: allows the user to tailor control to the application.
  • Multiple Program Set-ups: Up to seven distinct preset loop control profiles may be stored. Allows multiple tailored loop control algorithms to be instantly employed as required. Our 3CPO option allows quick operator control over presets.
  • Two or more may be used in close proximity: Simple multiplex setup eliminates crosstalk.
