A proximity sensor, like the TL-PP702 model, is a sensor that can identify and detect the presence of objects without any physical contact. Consider the iconic burglar alarm practical example. As soon as an intruder enters your home, the alarm is triggered due to the sensing of motion. In a similar fashion, industrial applications employ proximity sensors such as the TL-PP702 model to detect the motion of a range of objects, as well as sound, light and liquid levels, to facilitate reliable and accurate automatic operations.

In terms of its application field, the TL-PP702 model is specifically designed for industrial and professional applications. This includes manufacturing lines, robotics, oilfield automatic systems, level measurement, packaging equipment, pick-and-place applications, medical equipment, vending machines, ticketing machines, and many other areas. It can detect objects at distances ranging from 0-30mm (range depends on the model).

The TL-PP702 is a capacitive proximity sensor, meaning it works by sensing changes in electrical capacitance around it. There are two different capacitive proximity sensors, shielded and unshielded. The TL-PP702 is an unshielded sensor, meaning it does not need an interference-shielding layer to work. This type of sensor operates by sending a high-frequency alternating current signal from an internal oscillator that is received by circuitry within the area of its detection. When an object makes contact with the detection area, the electrical capacitance changes. This change influences the received signal and is transmitted to the proximity sensor’s output, triggering a change in its state. This change can then trigger an event, such as an alarm going off, or could just be detected through any number of automated systems.

The main advantage of capacitive proximity sensors is their accuracy and reliability. All capacitive sensors are designed and tuned to detect very specific material properties and change states when identifying objects of certain composition. Unlike other detection technologies, capacitive proximity sensors are not affected by changes in light, temperature, or electrical interference. This makes them a much more reliable and effective option for industrial and professional applications that require repeatability and accuracy, such as in a manufacturing line.

The TL-PP702 model is a great choice for applications that require accurate detection of objects without physical contact. Its robust design and sensitivity make it perfect for detection of both metals and non-metals and for automation of industrial processes. Its unique features, such as its high frequency alternating current oscillator, makes it more accurate and reliable than other detection technologies. The TL-PP702 is a great choice for industrial and professional applications that require accurate and reliable detection of objects without physical contact.
