Yarn Sensor: An improved replacement for the BTSR ® piezo type STCS yarn sensors on single and double cylinder computer controlled sock knitting machines.  The integrated tension device provides a complete replacement assembly.

Works with integrated internal controls or external CMP 24-32 control units.

• The "OPTOSTOP" dynamic opto-electric unit provides non-contact sensing of yarn movement.  With its design of the light source and light detector, the "OPTOSTOP" detects yarn movement across a wide "window".  Reliable detection of filament, textured and spun yarns of all sizes and types at every knitting speed is assured.
• The "OPTOSTOP" is an intelligent sensor with an integrated micro-controller for autonomous function.
• The circuitry of the "OPTOSTOP" is completely sealed for absolute protection from vibration, moisture, and solvents.
• All "OPTOSTOP" signals are compatible with the BTSR ® STCS Piezo unit that it replaces.  The existing cable connection plugs directly into the "OPTOSTOP" unit.
• Integrated LED affirms the yarn is running accurately, is stopped as programmed or is broken or missing.

Yarn Tension:

• The complete "Tension and Sensor" assembly can be quickly exchanged.
• Robust stainless steel support with smooth surfaces insures years of service.
• Non-contact detection and a metal support that eliminates static loading and insures minimum lint accumulation.
• Wide setting range of yarn tension.
