BNC Connectors Types & Applications


BNC (Bayonet Neill Concelman) Coaxial connectors are the mostly widely used RF connectors that are used in any coaxial or screened cable application, particularly RF applications. A BNC connector is used on test a wide range of device including oscilloscopes, audio generators, power meters and function generators.

Attributes of BNC Connectors:
The BNC Connectors uses a bayonet fixing to prevent accidental disconnection if the cable is repeatedly moved or pulled. It is a constant impedance connector or In other words, we can say that it has the same characteristic impedance across the whole of the connector. Coaxial cable has “characteristic impedance”. Consequently RF signals travelling along a coaxial cable will see no impedance changes as they pass through the BNC connector. Therefore, This is vital for RF applications as it will result in few reflections and a lower level of loss.

Types of BNC Connectors:
BNC Crimp on connector
BNC Crimp on connector is available in two types– 2 piece and 3 piece. To attach the BNC Crimp on connector onto a coaxial cable, additional tools needed are a coaxial cable stripper and a coax crimping tool.
Steps:
First Slide the crimp ferrule piece of the connector onto coaxial cable, slimmer side. Using a cable stripper, trim the jacket off the edge of the cable and peel it off easily. Fold the copper braiding over the long side of the cable and after that trim the interior insulation shielding the cable core. Slide the connector onto the cable and fold braid back over crimp body and push crimp ferrule up over braid and crimp body. With the help of crimping tool, crimp ferrule to connector. This is a very secure and easier method and is widely used by installers.
BNC twist on connector:
A BNC twist on connector is convenient in that it requires no additional tools in order to be attached to the coaxial cable, except for a cable stripper. Once the cable is stripped after that the rest of the work is done by hand.
Steps:
Strip the cable to reveal its inner part. After striping the cable cut the plastic jacket to reveal the copper braiding, and fold the braiding over the plastic shielding. Slide the bare inner part side of the cable into the BNC twist on connector and twist it clockwise to secure it.
BNC compression connector:
A BNC compression connector comes in the F connector style or once piece style. To fix the once piece BNC compression connector, you’ll require a stripper and a compression tool.
Steps:
Strip the jacket off the cable revealing the inner part of the cable. Next take the BNC compression connector and slid the inner core into the internal connector hole and push the cable into the connector into place. The inner part will come out through the connector. With the help of a compression tool, insert the connector into place and squeeze it tight, while holding the cable in place.

Different types of Limit Switches

Rotary Geared Limit Switches The operating of the Limit Switch is to prevent the mechanism or drive at the intense forward/reverse positions. The Limit Switches are significantly suited to use on reversing drives like a hoist, winches, rolling mills and various other mechanisms used in steel plants such as coke ovens, feeding machinery, valve drives etc. The contacts of Limit Switches are forty amps rated ceaselessly at 500 Volts A. C. The Limit switch is often supplied with two NC contacts or four NC contacts or (2 NO + two NC) contacts as per the need. For Series Limit Switches are shields are provided. The frequency of switching of each contact is suitable for a maximum of 720 operations per hour. The speed of the driving shaft rotation shouldn't be over 60 rpm. Features:- High durable standards Optimum performance Easy to install Counter Weight Limit Switches A metal structure offers the required stability to Counter Weight Limit Switches that job on heavy c

Solid State Relay AC & DC Input Circuit

Solid State Relays are semiconductor equivalents of the mechanical device relay and may be accustomed control electrical masses while not the utilization of moving parts. a normal electro-mechanical relay, SSR’s provide complete electrical isolation between their input and output contacts with its output acting as a conventional electrical switch in that it has very high, almost infinite resistance once nonconductive (open), and a really low resistance once conducting (closed). Solid State Relays can be designed to switch both AC or DC currents by using an SCR, TRIAC, or switching transistor output instead of the usual mechanical normally-open (NO) contacts. Solid State Relay DC Input Circuit When utilizing mechanical contacts, switches, push-catches, other hand-off contacts, and so forth, as the initiating signal, the supply voltage utilized can be equivalent to the SSR's base information voltage esteem, though when utilizing strong state gadgets, for example, trans

What is switching regulator? How does a switching regulator work?

switching regulator  A voltage controller that uses a changing component to change the supply into a rotating current, which is then changed over to an alternate voltage utilizing capacitors, inductors, and different components, at that point changed over back to DC. The circuit incorporates guideline and separating parts to safeguard an unfaltering yield. Switching regulators or DC-DC converters are used universally in almost all electronic devices. They are popular as they have high efficiency during both step up (boost converter) and step down (buck converter) of DC voltage. Below may be a simplified diagram of a buck convertor that is used to step down DC voltage. A controller IC is needed to sense the feedback voltage and alter the switching PWM consequently. Some DC-DC converters today replace the diode with a transistor for synchronous rectification for higher efficiency. This efficiency comes at a higher cost as a more complex driver is needed. How does a switch
