The Criteria to Consider While Choosing Circular Connector Types

Any electrical connector can be circular connectors if they have multi-pin interconnects featuring circular contact interface with cylindrical contact housings. A variety of circular connector types is there that are used for applications that demand high reliability such as military and aerospace.

Circular connectors are widely used for some of their unique capabilities. They can hold various types of contacts, provide solid mechanical performance, are compatible with a broad range of contact currents and voltages, and are capable of environment sealing with ease. On the other hand, their principal drawback when compared to rectangular connectors is the loss of panel space when used in groups.

Circular Connector

Selection Criteria of Circular Connector Types

Choosing the right circular connector is important to get the correct mechanical performance. There are some basic parameters that you have to consider while choosing circular connector types:

Gender

All connectors can be primarily divided into two categories – male and female. A male connector has pins that plug into a receiver with sockets while a female connector has sockets that connect to a connector with pins.

Terminals

A variety of terminal options is there that determine how the conductive element connects to the connector’s electrical contacts. Termination options include tabs, screws, PCB solder, solder cup, lugs, wire wrap, insulation displacement, and crimp.

Mounting

The connectors come with particular mounting types as they are required to mount on a circuit board, panel, cable end, or other points. Different mounting methods are available including inline cable mounts, jam nuts, bulkheads, and flanges.

Performance Criteria

You also have to consider several performance criteria for selecting the right circular connector types. Let’s take a look at the key performance factors:

  • Voltage and Current Ratings

The maximum rated voltage and current indicates to the highest amount of voltage and flow of electricity a connector can transmit, respectively. The size and type of contacts in the connectors typically control the voltage and current rating.

Connectors that are used for electrical signals and sensors have low amperage and voltage ratings. Power connectors, on the other hand, have a high voltage and current ratings.

The standard voltage ratings of the connectors are 50V, 125V, 250V, and 600V while the current ratings range between 1A and 50A.

  • Contact Number & Size

The contact number indicates to the number of conductive elements in a connector. On the other hand, the size of the contact can refer to either the termination size or the diameter of the contact.

The American Wire Gauge (AWG) is the standard according to which the size of the wire is measured in North America. The AWG number is conversely proportionate to the diameter of the wire. So, the thinner the wire is, the higher the AWG number.

Previously, the term circular connectors were used for circular plastic connectors (CPC), which were used in industrial applications for their ability to offer a secure connection and withstand hard environments. There are mil-spec connectors that are specifically designed for military and aerospace applications. You’ll also find DIN, micro, and nano connectors for different applications.

A Brief Guide to Understanding AC Drive System

The function of an AC Drive is to change the speed and torque of an electric motor (AC Motor) used in electro-mechanical drive systems by changing the frequency and voltage of the power supplied to the motor. An AC Drive system, which is also known as a variable-frequency drive (VFD), inverter drive, variable speed drive, and adjustable-frequency drive, mainly performs the speed adjustment of a motor.

AC Drive System

AC Drives Applications

The AC Drive system has a variety of applications in different electrical systems. Let’s take a look at some common uses:

Control Performance

AC Drives control the performance of various systems in commercial and industrial applications. They work for bringing the quality improvements of different systems’ speed, acceleration, tension, torque, flow, and pressure.

The advantage of using the drives is that they ramp up the motor to the operating speed gradually, reducing the electrical and mechanical stress on the motor and the driven equipment. On the other hand, fixed-speed load keeps torque and current surge at a high point at the beginning, creating damage risk for the motor and other equipment.

Energy Savings

The AC Drives provide the flexibility of tuning the configuration of a system to the most energy-efficient level. They help saving more energy than drives that offer the optimization of individual functions of a system.

HVAC Applications

AC Drives are most commonly used in compressors, pumps, and fans of HVAC systems. Using them other than any other tool in controlling the output of a fan, pump, or compressor system saves a substantial amount of energy.

AC Drives Working Principle

An AC Drive system converts the frequency of a power network, and thus controls the motor speed in a proportional rate to the frequency. Understating some simple basics of AC Drives will help you figure out their working principle. The procedure consists of:

Rectifier unit. The electrical network connects to the AC drive via a uni- or bi-directional rectifier unit. The AC Drive takes energy from the system and uses it to accelerate and run the motor if the rectifier is unidirectional. In the case of a bidirectional rectifier, the drive supplies energy to the network by taking mechanical rotation energy from the motor.

DC circuit. The DC circuit mainly assists the inverter by storing energy for it from the rectifier.

Inverter unit. It works as a bridge for the transmission of energy from the DC circuit to the motor. It creates the three-phase AC voltage output for the motor, which influences the motors speed aka output of the process. A higher frequency of the output voltage results in a higher speed of the motor.

Benefits of AC Drive System

AC Drives offer various benefits regarding system stress, process control, and energy savings of the motors they control. Some of the advantages are:

  • Gradually ramp up the torque and current surge, and thus reducing stress on the tools and machines
  • Reduce thermal and mechanical stresses
  • Cut the level of noise and vibrations in low load situations
  • Secure smooth flow of energy by synchronizing between different parts of the main process
  • Control the output of the process as required
  • Save energy more than the traditional methods of process control

What Is Cable Tray Fitting?

A cable tray fitting is a device that performs the task of changing the elevation, direction, or width of a cable tray system. A range of fittings makes the system fully customizable to lodge any tricky configuration.

Take a look at several types of cable tray fittings:

Flat Elbow

Flat elbows create fixed angular changes in direction in the same plane, between horizontal or vertical cable tray runs, depending on where the installation of cable tray is done in a horizontal or vertical plane, respectively.

There are also 30, 45, 60, and 90 degrees elbows.

Variable Risers

Risers create angular changes in direction between cable tray runs in various planes. You can use them in both horizontal and vertical planes.

Equal and Unequal Tees

Equal tees have an identical main width (Wm) and branch width (Wb) while it is different in the case of unequal tees.

Crosses

Crosses do the job of creating right angle intersections in the same plane. The intersections are created between horizontal or vertical cable tray runs based on whether the cable tray is installed in a horizontal or a vertical plane, respectively.

Straight Reducer

The primary function of straight reducers is to produce a concentric reduction. They share a uniform width reduction along both sides.

Left Hand Reducer

Left hand reducers do the function of creating offset reductions to meet the installation requirements of different sites. They have a width reduction along the left side.

Right Hand Reducer

Right hand reducers also do the job similar to left hand reducers. However, they have a width reduction along the right side.

A/V Connectors

For Your Safety: Electrical Layout in Your Workspace

If you are doing electrical wiring in your workspace, the key to success is in your planning and layout. Knowing what electrical supplies to use, the size of your workspace, the location of your outlets and circuits and the pieces of your larger electrically powered equipment is all key. Here are some things you may want to consider when figuring out the layout for your electrical wiring to ensure a job done correctly and safely.

Electrical Layout

Large pieces of equipment should have their own dedicated circuits. It’s a good idea to know where your equipment will be while working and make the dedicated circuits easily accessible to that area. It’s also a good idea to equip every circuit with a GFCI which will shut the power down in the event of a short and reduce the possibility of an electric shock.

Also, make sure you have enough outlets before starting. Typically, people find that they need more outlets than they first anticipated. Therefore, it’s a wise idea to plan for more outlets rather than less. Also, consider the height of your receptacles. Higher outlets may be best in workshop settings which eliminates access problems that might arise with lower receptacles when tools are placed along the walls.

When wiring overhead lights, it’s a good idea to keep them on separate circuit from the wall outlets. That way, if the wall outlets overload, you will still have light in your workspace.

The breaker box you are using should have clearly labeled switches indicating which tools are operating from which outlets. Most equipment will require a 240V outlet while pieces like air compressors or welding equipment may need a higher voltage. Your breaker box should be appropriately labeled to avoid confusion.

Adequate lighting is also key in a workshop setting. Electrical supplies offer a number of options for lighting including fluorescent overhead fixtures which are inexpensive, easy to install and offer a nice even light. Undercabinet lighting can be ideal for shelves ensuring easy access to tools stored there. Track lighting can be good for illuminating specific parts of the room because individual bulbs can be directed to light up different areas of your workspace. Portable flood lights are adjustable and very bright and can be handy if you are setting in a specific area to work.

Of course, the first step in all this is finding the best electrical supply store for your circuits, outlets and lighting. There are several electrical supply stores and houses for all your layout needs. Electrical wholesale could be useful to electricians who are looking to buy in bulk. Electrical supplies online is also a great option but be sure to read the descriptions carefully to make sure you are getting the product that suits your needs.

Those that are looking for convenient electrical wiring are advised to leave this work to an electrician for optimal safety. However, it’s a good idea to supervise as no one knows your workspace quite like you do. Good luck in making your workplace safe and easy to use!
