Elevator Door Monitoring
Installed within elevator systems, it identifies the door’s open or closed position through the metal structure. The IP67 housing protects it from humidity and dust, supporting maintenance-free operation in enclosed shafts.
Crane End Position Sensing
Used to detect the end-of-travel position on overhead cranes. The sensor’s shock resistance and extended sensing distance help maintain reliable position feedback despite vibrations and heavy-duty use.
Gear Tooth Detection in Rotating Equipment
It tracks the passing teeth of a rotating gear to ensure synchronization. Its rapid response time and high precision enable accurate speed measurement and timing control in mechanical drives.
Valve Position Feedback in Chemical Processing
The sensor detects valve stem position without physical contact. Thanks to its corrosion-resistant housing and sealing, it performs reliably in environments exposed to chemicals and temperature shifts.
Forklift Lift Height Detection
Mounted on lift trucks to monitor metal fork or pallet height. The long-range detection and IP-rated sealing ensure accurate position control in warehouse environments full of dust and frequent motion.
Revolving Door Segment Tracking
Identifies metallic door segments during rotation. Its durability and extended detection range make it ideal for commercial entrances with frequent use and changing environmental exposure.
Escalator Step Speed Monitoring
Detects individual steps made from metal to monitor movement speed. The sensor’s fast switching capability ensures each step is tracked reliably, aiding in escalator safety and control system feedback.
