Linear measurement sensors

Your Benefits

  • Non-contact measurement ensures high level of repeatability
  • Process and quality optimization thanks to precise speed and material detection
  • Significant reduction in material costs due to non-slip cutting control
  • High degree of flexibility thanks to material-independent measurement
  • Cost-effective solutions with an attractive price-performance ratio
  • User-friendly process integration using configurable multifunctional interface
  • Easy replacement of existing mechanical systems
  • The maintenance-free, non-contact measuring system significantly reduces maintenance costs


Tactile measuring wheels, measuring rollers or tachometers often cause measuring errors and damage to measured objects due to slippage, vibration, contamination and wear. The compact OLV range of linear measurement sensors from SICK offers an accurate, user-friendly and durable solution for such systems. Your decisive advantage: they provide a non-contact, material-independent measurement.These non-contact, material-independent sensors, which are based on the laser-Doppler principle, deliver a typical measurement accuracy of ± 0.05%. The OLV sensors are lightweight, maintenance-free, permanently calibrated and measure practically any surface or color without parameter reconfiguration.
