In today’s world, RFID transponders, tags and other technologies have become an integral part of how businesses track, manage and control goods in their operations. One of the most commonly used RFID products is the PCF7939PA/C0BC1200 transponders. This article will discuss the application fields of this product as well as the working principle behind it.

The PCF7939PA/C0BC1200 transponders can be used in several different applications. For example, it is widely used in the automotive industry in order to track and monitor keyless entry systems for cars as well as engine immobilization parameters. In addition, it is also used in the healthcare industry to monitor and control numerous medical devices such as insulin pumps, cardiac pacemakers and hearing aids. In the logistics industry, its use is very widespread in order to enable inventory control as well as track the movement of products. In the retail industry, it is frequently used to track and monitor merchandise.

The working principle of the PCF7939PA/C0BC1200 transponders is based on radio frequency identification (RFID). This technology makes use of electromagnetic fields to identify and track objects that are equipped with RFID tags. The RFID tag contains a chip which stores information related to the object and an antenna which allows for the transmission of this information to a reading device. When the reading device passes in close proximity to the RFID tag, it sends out a radio wave which activates the chip. This triggers the RFID tag to transmit the encoded information stored in the chip to the reading device.

The PCF7939PA/C0BC1200 transponders operate on a frequency of 125 kHz. This low frequency has several advantages. One of the most important of these is that it has a longer read range than other frequencies, making it suitable for many applications. Additionally, it has lower power requirements than higher frequencies. This makes the transponder more power efficient, reducing the cost of ownership.

The PCF7939PA/C0BC1200 transponders are also very secure. These transponders are encrypted, rendering them virtually impossible to clone. Furthermore, these transponders also feature a 64-bit read only unique ID number. This prevents unauthorized access by ensuring that the transponders may only be accessed by the intended user or device.

In conclusion, the PCF7939PA/C0BC1200 transponders are widely used in a variety of fields due to their versatility, power efficiency and security. The working principle of these transponders is based on RFID technology, whereby radio waves are used to trigger the chip in the RFID tag. This triggers the transmission of encoded information from the chip to a reading device. The low frequency of 125 kHz also makes the transponder suitable for many applications due to its longer read range and lower power requirements.
