Proximity sensors are electronic devices designed to detect the presence of objects without contact. Application fields of proximity sensors can vary greatly depending on specific type of the sensor. UM18-21212A211 is a type of proximity sensor that works based on the principle of magnetic induction.

This type of proximity sensor is mainly used in applications requiring a compact and narrow-profile sensing solution. It is a non-contact metal detector, which utilizes a coil as an inductor. When a metallic object enters the coil, it forms a closed magnetic loop, therefore increasing the inductance of the coil. The increase in inductance is detected and output in voltage levels. This makes it possible to detect the presence of metallic objects at a fixed distance and activte the appropriate response function accordingly.

Unlike other proximity sensors, UM18-21212A211 has a much narrower profile, and is able to detect very small changes in ferromagnetic objects. This makes it suitable for applications that require non-contact detection of metals in restricted spaces. It is also highly resistant against electrical interference and is able to work reliably within flat and steep surfaces.

This proximity sensor can be used in a wide variety of industrial and automotive applications, which require a reliable and precise sensing solution. Some common applications include: object detection in small apertures, detection of containers in automated packaging lines, detection of different metals in scrap collection systems, material handling by robots, and safety systems for sliding or moving doors.

In addition, the UM18-21212A211 sensor can also be used in medical diagnostics applications, such as detection of metallic foreign objects and body tissues. Furthermore, it can also be used for detecting the presence of magnetic fields generated by permanent magnets, loudspeakers, and electrical motors.

The UM18-21212A211 is powered by 12 or 24 V DC. It has an output load of 0.5 to 15 mA, and a response time of 2.4 ms. It is also waterproof and corrosion resistant, making it suitable for use in extreme industrial environments.

Overall, the UM18-21212A211 proximity sensor can be used in a wide variety of industrial and automotive applications, and is an ideal choice for applications requiring a compact and narrow-profile sensing solution. This sensor is highly reliable, and can detect very small changes in ferromagnetic objects. It is also waterproof and corrosion resistant, making it ideal for use in extreme industrial environments.
