M18 Capacitive Proximity Sensor, PNP/NPN, NO/NC

Proximity sensors are widely used to detect the stop, start, and moving positions of elevators and lifting equipment. They help determine vehicle positions to prevent collisions, set working machine positions, and identify the limiting positions of removable parts. They also detect rotational stop positions, valve opening and closing positions, and the movement of hydraulic or pneumatic cylinder pistons.

They assist in size control for metal plate punching and shearing, automatic identification of metal piece length, and stacking height control. They detect the presence of packaging boxes or product parts on production lines. They regulate conveyor or rotating machinery speed using pulse signals and count items such as products on the production line or revolutions of high-speed shafts and disks.

Proximity sensors can detect abnormalities such as bottle cap presence, product quality differences, metal vs. non-metal parts, product labels, crane danger zones, and escalator start-stop conditions. They also support metrological control, including automatic measuring of products, monitoring meter ranges and flow, detecting buoys for level control, and managing upper/lower limit measurements. Additionally, they identify coded objects and enable information transmission for sensors connected to ASI bus systems over distances of 50–100 meters.
