Proximity sensors are used in many types of applications that require knowledge of the presence of an object without having to touch it. The TL-N7MD2 Proximity Sensor is one such device that is designed for ease of installation and maintenance in industrial applications. This section will discuss the application field of the TL-N7MD2 and its working principle.

Application Field of the TL-N7MD2

The TL-N7MD2 is a non-contact, inductive proximity sensor that is designed for industrial safety and process control applications. It is capable of detection of metal targets such as iron, steel, aluminum, and other metals up to 3mm away. This makes the TL-N7MD2 ideal for applications such as edge detection, level detection, speed detection, and position detection. It can be used for detecting objects in hazardous environments as it is certified up to IP67 for protection against water ingress. The TL-N7MD2 has a maximum sensing distance of up to 3mm and can operate on a wide range of power supply voltages starting from 5V up to 20V DC.

The TL-N7MD2 is exceptionally suited to be installed in environments where tight spaces exist such as conveyor lines, industrial robots, and machine tools. The embedded extension cable can be as long as 5m making it ideal for applications where the sensor has to be placed away from the space to be monitored. Its narrow beam aperture and adjustable sensing range makes it easy to use for highly precise applications.

Working Principle of the TL-N7MD2

The TL-N7MD2 is an inductive proximity sensor that uses an inductive coil to detect metal targets. It detects the target through the transmission of an electromagnetic field. This electromagnetic field induces an electrical potential in any conductive material that passes through the field. When the target object approaches the TL-N7MD2, the electrical potential on the target increases and this increases the flux in the coil. This causes the impedance of the coil to decrease and the output of the TL-N7MD2 changes according to the resistance it is detecting.

When the target is beyond the sensing distance of the TL-N7MD2, its output remains off. As the object approaches the sensing range, the output of the device changes to ‘on’. The TL-N7MD2 also has a built-in LED indicator that also helps to indicate the status of the device. This makes the TL-N7MD2 ideal for applications where visual indication is necessary. The TL-N7MD2 is designed to be highly reliable, robust, and has a long operating life.

With its wide range of capabilities and its ease of installation and maintenance, the TL-N7MD2 has quickly become a popular choice among engineers for proximity sensing applications. Its small size, selectable operating voltages, and high precision make it ideal for a variety of industrial applications.
