Application Field and Working Principle of ARJM11D7-811-NN-ER2-T Modular Connectors - Jacks With MagneticsModular connectors - Jacks with magnetics are widely used in electrical and electronic applications for providing valuable electrical and mechanical connectivity in an efficient way. ARJM11D7-811-NN-ER2-T is one of the most popular modular connectors from the Amphenol range of products. This type of modular connector is used in applications where physical space availability is limited but substantial current levels need to pass through. This makes it perfectly suitable for modern electronic devices, as it offers reliable and efficient mechanical and electrical connection in a compact size.The ARJM11D7-811-NN-ER2-T is designed with two rows of contact pins that have three pins in each row. It also contains one magnetically shielded chokes and one divide, along with a conductive metal shell. The chokes in the connector provide a continuous low-pass filter, while the divider is responsible for providing a high-pass filter. The conductive metal shell gives additional grounding protection and helps to reduce system noise. This type of modular connector is designed to meet all the standards set by the International Electrotechnical Commission (IEC).The ARJM11D7-811-NN-ER2-T has excellent electrical characteristics such as a DC resistance of 0.09 ohms/contact and a current rating of 2A. In addition, the connector has an excellent surge/transient protection rating of 600V. The combination of the electrical characteristics and the mechanical characteristics of the connector provide a reliable connection and a long service life.The working principle of the ARJM11D7-811-NN-ER2-T modular connector is based on two main components: the transformer and the magnetics. The transformer is responsible for providing electrical isolation between the low voltage and the high voltage signals, while the magnetics provide an additional noise reduction. The transformer is connected between two rows of contact pins and it contains a small toroidal core made of iron. The core of the transformer is connected to two coils which act as a high-pass filter and a low-pass filter.When a signal passes through the coil, the core creates a magnetic field that is then used to reduce the electro-magnetic-interference (EMI). The core also helps to reduce the signal-noise-ratio (SNR). The shield chokes are integrated with the transformer and will help to reduce the EMI to the circuit. The magnetically shielded component used in the ARJM11D7-811-NN-ER2-T is composed of two parts: the shield and the magnetics. The shield is made of a conductive surface which is intended to reduce the EMI influence from external sources. The magnetics in the connector provide a low-pass filter that helps to reduce the high frequency emissions. The ARJM11D7-811-NN-ER2-T is one of the most versatile and reliable modular connectors available today. With its excellent electrical and mechanical characteristics it is particularly suitable for applications where limited space is available and higher current levels are needed. The combination of the chokes, divide, metal shell and the magnetically shielded component provide the perfect way to reduce EMI and maintain reliable connections over a long period of time.
