Product Overview & Technology
Industrial sensors are devices used to detect physical objects, changes, or states without physical contact. Switza manufactures high-sensitivity proximity sensors (inductive and capacitive) and photoelectric sensors designed for high-speed object detection, positioning, and count tracking on automated assembly lines.
Key Features & Benefits
- check_circleNon-contact detection prevents wear and tear on both the sensor and the target object.
- check_circleHigh switching frequency for rapid object counting and speed monitoring.
- check_circleRobust nickel-plated brass or plastic housing with IP67 ingress protection against dust and liquid splash.
- check_circleShort-circuit, reverse polarity, and surge protection built into all sensor models.
Industrial Applications
- settingsObject detection, sorting, and counting on packaging and conveyor lines.
- settingsPosition sensing, limit checking, and alignment on CNC and assembly machinery.
- settingsRotational speed (RPM) monitoring of shafts, gears, and fans.
- settingsMaterial level detection (liquids, grains, plastic pellets) in hoppers.
Frequently Asked Questions
Inductive proximity sensors can only detect metallic targets by generating an electromagnetic field. Capacitive sensors can detect both metallic and non-metallic objects (like plastics, liquids, glass, and wood) by measuring changes in electrostatic capacitance.
NPN sensors switch the ground (negative) line to the load, meaning the signal wire goes negative when activated. PNP sensors switch the positive power line to the load, meaning the signal wire goes positive (V+) when activated. Select the type that matches your PLC or controller input.
Our standard cylindrical proximity sensors offer sensing ranges from 1mm up to 15mm depending on the sensor diameter (M8, M12, M18, M30) and mounting style (shielded/flush vs. unshielded/non-flush).
