Proximity sensors: Working principle, types and applications
Oct 10, 2022 · Magnetic proximity sensors detect a target by using an external magnetic field. A typical magnetic proximity sensor features two ferromagnetic reeds (or contact blades) sealed in a glass casing filled with inert gas. When this casing is approached by the target (usually a permanent magnet), the contact ends attract each other and make contact.
Bipolar junction transistor: Operating principles, types and ...
Jan 15, 2024 · A BJT is a three-layer semiconductor device that serves as a key building block in electronic circuits. BJTs fall under the category of transistors, which are semiconductor devices that can amplify or switch electronic signals. The three layers of a BJT are the emitter, base and collector. The arrangement of these layers creates two ...
Where RoHS, REACH and PFAS intersect | Electronics360
Jun 6, 2024 · In the electronics industry, the two major regulations are the RoHS Directive and the REACH Directive, both of which originate as EU directives governing the use, import and sale of substances known to be hazardous to the environment and human health. These two EU directives have their analogues in the US, China and other developed countries.
DC Motor Calculations—Part 1 | Electronics360 - GlobalSpec
We can consider a DC motor in terms of the input-output relationship. The input parameters are the supply voltage (E) and the supply current (I) and the output mechanical parameters are the torque (T) and the rotational speed (ω). A representation of the functional block diagram is shown in Figure 1. Figure 1: DC motor block diagram.
5G vs 4G frequency spectrum comparison | Electronics360
Aug 24, 2020 · The first band is known as Sub-6 GHz bands, and it works in 5G, just like it works in 4G. The transmitted frequency in this band is less than 6 GHz and the cell phone towers transmit frequency using this band spectrum. The second frequency band creates a major difference between 5G and 4G. It is a high-frequency band with millimeter-wave ...

Working principles of inductors and capacitors | Electronics360
Feb 6, 2024 · Inductors and capacitors both store energy, but in different ways and with different properties. The inductor uses a magnetic field to store energy. When current flows through an inductor, a magnetic field builds up around it, and energy is stored in this field. The energy is released when the magnetic field collapses, inducing a voltage in the ...
An introduction to 5G New Radio architecture | Electronics360
Jul 14, 2022 · Source: Matt Lee The new wireless access network architecture means that 5G base stations will have a variety of deployment forms. There are two scenarios: distributed radio access network (D-RAN) and centralized radio access network (C-RAN). C-RAN is subdivided into two deployment modes: C-RAN small concentration and C-RAN large concentration.
Basics of inductors: Working principle, calculations, circuits and ...
Oct 25, 2022 · Where: L = inductance (Henry) V = voltage across the inductor (volts) di/dt = instantaneous rate of electric current change through the inductor. The inductance of an inductor is a result of the induced magnetic field in the coil. It depends on several factors, including the length of the inductor coil, number of turns and coil diameter.
