The difference between circular and rectangular cable connectors

cable connectorsWhen it comes to cables, everything can be a bit overwhelming. Thankfully when you look for it, there is a whole range of information available at your fingertips. While there is much available for your personal reading, sometimes things are best left to the experts, so depending on the difficulty and your ability, you’ll have to decide what’s best. Here we will address the common difficulty in understanding the difference between different types of cable connectors available for your use.

Having the wrong connector in operation is not only a time consuming and costly problem for you, but also incredibly disadvantageous to business.

Circular Connectors

The most widely used cable connect is of course the circular one. While it is hugely common, the rectangle type is also, making it sometimes difficult to understand why there is a need for these two different types.

The circular connector head is especially useful when it comes to an application that uses servo motors and harnessing. While dependent on your working environment, you should use a supplier that will be able to assist you with any information or requirements, as they are in the position to give you accurate advice on all things cable.

Before purchasing a circular connect, you should understand its durability quality and decide if it is fitting with the application it is about to be deployed into.

Rectangular Connectors

Considered for slightly more heavyweight applications than the circle version, the obvious distinguishing feature is of course the shape. You will primarily find the rectangular versions in processes where there is a greater danger threat to the cable. This could be through human error, hazardous interference or elemental conditions having an effect.

The fact that rectangular head connectors are less commonly seen is due to the fact that they are used in more industrial environments, whereas the circular connector is used across many household appliances.

Before plunging into the world of cabling and connecting up your applications, it is always advisable to consult the cable experts at organisations such as Lapp, as they are able to offer sound advice that keeps things efficient and moreover, safe.

Solar Connectors

A relatively new addition to the cable connector scene, the solar connectors are set to grow significantly with the embracing of solar energy. Somewhat once seen as a gimmick, the solar energy demand is growing significantly, and expects to reach the point where at least a house on every road will be seen to have a solar panel on their roof.

To achieve the best performance from your solar energy, the most effective transmission of the power is necessary. If your applications are constantly exposed to heat as many are, it will be totally worthwhile to engage in some preventative and protective strategies in the form of suitable connectors.

EPIC Ultra Cable Connectors: Why are they ideal for your application?

EPIC Lapp cable conenctorsThe Lapp Group have a wide selection of cable connectors available, with lines of both rectangular and circular connector housings. These have been designed to thrive in corrosive, electrically noisy or mechanically challenging environments.

EPIC Ultra is a particular range of housing that features nickel-plated zinc hoods and bases with stainless steel hardware. These corrosion resistant materials allow the new housing to survive in applications that would be challenging for housings that consist of traditional painted aluminum.

This range also features an integrated brush-style cable gland, which provides a fast and easy method to terminate a cable shield with a 360-degree, low resistance contact area. This feature forms a conductive shell alongside the nickel-plated housing, around the electrical contacts to virtually eliminate electrical interference.

The connector housing’s unique mechanical design improves both sealing and strain relief. EPIC® ULTRA’s built-in cable gland not only improves sealing and strain relief but also speeds assembly and eliminates a possible leakage point. Additionally, the lip seal between the top and bottom housing components has been recessed so it is totally enclosed by the housing when mated and latched. This design feature protects the lip seal from mechanical damage and exposure to UV radiation when installed outdoors.

Rectangular connectors are a system of housings, inserts and contacts that come together and provide robust, secure and easy to assemble solutions. There are a range of other connectors other than the EPIC Ultra variety including MC Modular, H-B Housings and HD Inserts. The latter is available from 3 pin contacts up to 64, but is dependent on your voltage and current requirements.
