Why Choose Our Capacitive Proximity Switches
Our sensing solution utilizes advanced capacitance measurement technology and powerful signal processing to achieve highly reliable non-contact detection of almost any material, regardless of its color or transparency. Our capacitive proximity switch has excellent anti-interference ability and a durable fully packaged design, providing stable performance in challenging environments. Through simple and precise sensitivity adjustment
High Sensitivity and Stable Switching
Our capacitive switches are designed for highly reliable, non-contact material detection. Their sophisticated sensor field ensures immediate and stable switching output upon target presence, minimizing false triggers and guaranteeing accurate detection for process stability, particularly in level and material flow applications.
Compact Design and Versatile Mounting
Featuring robust, space-saving cylindrical and rectangular housing, our sensors are easily integrated into crowded machinery and tight spaces. The ability to sense through container walls simplifies installation and isolation from the media being detected.
Maintenance-Free and Low Power Consumption
The sensing principle is purely electronic and non-invasive, requiring zero mechanical contact or moving parts. This results in extremely low power consumption and a high Mean Time Between Failures (MTBF), drastically cutting down operational costs and eliminating routine maintenance.
Universal Material Detection
Unlike many other sensors, our capacitive switches detect virtually all materials, including plastics, glass, wood, chemicals, powders, and especially liquids. They reliably output signals regardless of the target’s color, transparency, or reflectivity, offering unparalleled versatility.
Robust Encapsulation and Longevity
Our highly integrated electronic circuits are fully encapsulated within durable industrial-grade casings (often IP67/IP68 rated). This full protection shields the core components from dust, moisture, and vibration, ensuring exceptionally long-term stability and a maintenance-free lifespan.
Extreme Reliability in Harsh Environments
Built upon years of professional experience in sensor manufacturing, our products feature outstanding anti-interference circuitry. They maintain stable and reliable performance and accurate detection data even when exposed to high humidity, strong dust, and high vibration common in heavy industrial settings.
