Proximity Sensor

Professional repair of inductive, capacitive, optical (photoelectric) and ultrasonic proximity sensors focusing on restoration of high-frequency oscillator circuits, weak-signal amplifiers, threshold comparators and switching outputs (PNP/NPN or analog). Common faults include reduced detection sensitivity due to damaged ferrite cores or sensing electrodes, high noise susceptibility, unstable oscillator operation, burned output transistors and moisture ingress into the housing. The repair process includes electrical parameter testing with dedicated equipment, readjustment of switching distance, restoration of protective coatings and final calibration according to IEC 60947-5-2 standard. These sensors play a critical role in automated production lines, packaging machinery, safety systems and robotics.
