The document discusses an inductive displacement sensor for calibrating robot axes. Some key points: - The sensor is used to acquire the zero point and adjust robot axes during setup and quality assurance checks. It provides a definite and reliable adjustment independently of the operator. - The rugged stainless steel housing and probe design ensure long service life in harsh industrial environments. - The complete calibration set includes the KTL-gaging sensor, 5m connecting cable, screwdriver, and carrying case. It represents an essential aid for reliable robot operation. - Measurement requirements for the system include a measuring range of 5mm, speed between 100um/s and 1mm/s, and operation time under 8ms
