Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, introduced the RAA78815x Family of 5V differential RS-485/422 transceivers with electrical fast-transient (EFT) immunity ±5000V and ESD protection up to ±16,000V. These products are the ideal solution for noise-sensitive industrial communication networks. The six new full and half-duplex ruggedized devices meet both the RS-485 and RS-422…
Let’s take a journey to the world of the electrical connectors. What is an electric connector? It is a simple, small size electro-mechanical device. It is basically use to connect two or circuits together. It is possible for the circuits to transfer power or signal through the connectors. Connectors have one more metallic structure inside it for electrical connections.The connectors always provide a temporary connection between the circuits. This temporary connection has so many advantages over the permanent connections. You can easily replace a particular circuit in a system; you can check the input or output of a circuit independently etc. Moreover the connector provides easy assembling and troubleshooting. An electrical connector is made of two things, conductors and insulators. Usually there is more than one conducting path for power or signal separated by insulators.A conductor as we all know allows electricity to flow through it, offers very low resistance. They are used to make physical contacts through which the electric current can flow through.
A reed switch consists of two ferromagnetic nickel-iron wires and specially shaped contact blades (reeds) positioned in a hermetically sealed glass capsule with a gap between them and in a protective atmosphere. The glass capsule is filled with inert gas to prevent activation of the contacts. The ruthenium or rhodium plated contact surfaces are isolated from the outside environment, which protects the contacts from contamination. Reed switches can be operated using a magnetic field generated by either a permanent magnet or current-carrying coil. They induce north (N) and south(S) poles on the reeds. The magnetic attractive force leads to closure of the reed contacts. Upon removal of the magnetic field, contact open again due to the elasticity of the reeds. There are Reed Switches which operate with permanent magnet, while there are Reed Switches operate with coils which can be magnetized by sending current through them.
What would the cars run on if one day the fuels that we’ve been lavishing on for so long just disappeared? Earth had once been a planet replete with stockpiles of consumable fossil fuels like coal and petroleum. But as mankind progressed and advanced its appetite for energy shot up to humungous proportions and in much less than three centuries since the Industrial revolution, there is an outcry to conserve these natural resources and look for alternatives. Of all the industries that would directly or indirectly hit the consumers if these fuels disappeared from earth, the most obvious would be the automobile industry. To offer a viable solution to these dilemmas, many innovations in the field of automobile industry have taken place from time to time. One of them is ‘electric cars’, a solution for a cleaner and healthier tomorrow.
