In the automated door‑module installation cell on a vehicle chassis, the inductive sensor is fixed to the robot’s end‑effector. It continuously checks whether a metal door panel is correctly captured before the robot moves to the welding station. When the panel reaches the predetermined position, the sensor’s magnetic field confirms the presence of the ferrous part and sends a pulse to the PLC, which then authorises the next motion step. This feedback prevents the robot from attempting a weld on an empty or mis‑aligned fixture, reducing scrap and downtime. The same sensor type is often used in the paint shop to verify that a metal body shell has arrived at the spray booth, allowing the system to start the coating cycle only after confirmation. By providing reliable, contact‑free detection of metal components, the sensor enables precise synchronization of mechanical actions across the line, ensuring that each welding or painting operation occurs only when the part is truly in place. This role is essential for maintaining high throughput and quality in vehicle manufacturing.
