Proximity Sensors
Magnetic Field Sensors
Magnetic field sensors are designed to detect the presence of a magnetic field, typically from a permanent magnet. They are ideal for position detection, limit switching, and speed monitoring in industrial automation. Often used in harsh environments, these sensors operate reliably through non-metallic surfaces like plastic or aluminum. Common applications include cylinder position sensing, door monitoring, and conveyor systems.
Key Features:
- Non-contact detection
- High durability and vibration resistance
- Suitable for enclosed or inaccessible areas
- Common in pneumatics and mobile machinery
Capacitive Sensors
Capacitive sensors detect both metallic and non-metallic objects—including plastics, glass, wood, liquids, and powders—by sensing changes in capacitance. They are commonly used in level detection, bulk material handling, and object counting in automated production lines. These sensors are highly versatile and adjustable for different dielectric materials.
Key Features:
- Detects solid and liquid non-metallic materials
- Adjustable sensitivity
- Flush and non-flush mounting options
- Ideal for plastic, glass, and packaging industries
Inductive Sensors
Inductive sensors are non-contact proximity sensors that detect only metal objects by generating an electromagnetic field. Rugged and precise, they are widely used in harsh industrial environments for object positioning, counting, and automation control. Inductive sensors offer long service life, fast response time, and high reliability.
Key Features:
- Detects only ferrous and non-ferrous metals
- Immune to dirt, oil, and moisture
- Compact designs available for tight spaces
- Ideal for robotics, assembly lines, and CNC machinery
