faraznizamani said:I want to use an "inductive proximity sensor" for metal detector gate, but the problem is its range is (generally) under 50mm (2 inches), is there any way I can increase its range?
or is there any alternate sensor or way to detect the metal ?
Thank you.

A proximity sensor in a metal detector gate is a type of sensor that is used to detect the presence of metal objects in close proximity to it. It works by emitting an electromagnetic field and measuring changes in that field caused by nearby metal objects.
A proximity sensor in a metal detector gate typically consists of an oscillator circuit, a coil, and a detection circuit. The oscillator circuit produces an electromagnetic field, while the coil acts as a receiver for any changes in that field caused by nearby metal objects. The detection circuit then interprets these changes and triggers an alarm if a metal object is detected.
A proximity sensor in a metal detector gate can detect a wide range of metals, including ferrous and non-ferrous metals. This includes common metals such as iron, steel, aluminum, copper, and gold.
Yes, a proximity sensor in a metal detector gate can differentiate between different types of metal based on their electrical and magnetic properties. This allows for more precise detection and discrimination between different types of metal objects.
Proximity sensors in metal detector gates are highly accurate and reliable. They are designed to detect even small metal objects and can be calibrated to adjust their sensitivity based on the specific needs of the application.
