Surface-mounted non-contact inductive proximity sensors with nickel-copper housing | for detection of metal objects in automation control | monitoring systems
-
Non-contact inductive proximity sensors – one of the most popular automation components, used wherever it is necessary to accurately detect metal objects without physical contact. Non-flush sensors with a nickel–copper alloy housing stand out for their greater detection distance, reliability, and resistance to environmental influences. Widely used in industrial, transportation, production line, robotics, and automation control systems, as well as in electromechanical projects where precise signal transmission and long-term operation are essential.
Main functions and operating principle
Inductive sensors operate on the principle of electromagnetic induction – they create a high-frequency electromagnetic field that changes when a metal object enters it. The changed field generates a signal that allows the system to recognize the object or trigger a control action (e.g., turn on, off, or stop a device).
Non-flush sensors have a wider detection field and higher sensitivity, making them ideal when objects need to be detected not directly adjacent to the sensor surface.Applications
For home users: Used in automatic gates, doors, and alarm control systems. Enable reliable and durable non-contact switching mechanisms without physical wear.
For engineers: Excellent choice for automation system integration, production equipment monitoring, metal processing lines, robotics, conveyors, and transport systems.
For electricians: Easy to install, with standardized threaded housings, LED indication, and DC power compatibility. The IP67 protection rating allows installation in humid or dusty environments.
