Automotive Connectors – Industry Guide

2nd December 2019  |  Guides

Automotive connectors include both power connectors associated with wire vehicle harnesses as well as electronic connectors which are used in the automotive electronics and passenger restraint, security and passenger cars, trucks, buses and off-road vehicles.

The growing integration of automotive electronics including airbag systems, lane departure warning systems, and more are driving the growth in demand for automotive connectors.

Certain essential parameters include the operating temperature, IP rating, vibrations, shock, level of corrosion.

While the basic function of connectors is to provide electrical interconnections to complete the circuit, the type of connector system used is determined by a large number of non-electrical factors. First of all, it is necessary to consider mechanical requirements such as size, shape, mounting, mating and unmating force and frequency.

For each type of connector housing and electrical contacts, the environment has a major impact on the design and material chosen. For example, applications outside versus indoor may have a major impact on terminal design and the material used. The development and selection process is further complicated by environmental conditions such as temperature, temperature cycle, humidity, pollutants (solid, liquid and gaseous), shock and vibration and sealing.

Connection technology has evolved into a complex engineering discipline to satisfy these often contradictory requirements. Connection engineers ‘ job is to design the lowest-cost solutions that fulfil all specifications, which in fact also operate for cross-purpose purposes.


Automotive connector industries

Agricultural industry

Vital parts of the farming process are affected by adverse conditions. The consequences of an electrical connection failure can be severe to the day to day running of the farming process. That’s why farmers use TE Connectivity DEUTSCH products to keep their agricultural equipment running.

Construction industry

DEUTSCH products are designed to withstand all weather conditions, anytime of the year. Failures in construction equipment are not only expensive but can also affect the operation of a project running. TE DEUTSCH range are designed to withstand the challenges of the construction industry.

Emergency vehicle applications

Emergency vehicles such as fire engines, ambulances and police cars feature complex electrical systems that need to be kept running at all times. Operational issues can cost lives. Many of these vehicles are fit with TE Connectivity DEUTSCH products to deliver power consistently to their electrical connections.

Forestry industry

The forestry industry needs reliable electrical connections to keep its equipment operational in a variety of adverse conditions, such as extreme weather or exposure to chemicals. TE DEUTSCH connectivity solutions maintain power to the electrical connections of forestry equipment to keep the industry alive whatever the weather.

Marine industry

TE DEUTSCH is renowned for its reliability in the marine industry, and its solutions are used by many manufacturers of boats. Moisture, salt spray and humidity can all be critical factors to connectors at sea, but TE DEUTSCH’s environmentally sealed connectors are designed and tested to withstand immersion in three feet for prolonged deployment under harsh marine conditions.

Material Handling / Lifts applications

The material handling industry relies on a wide range of electrical equipment to manoeuvre their vehicles. TE DEUTSCH design solutions make the use of such equipment as secure as humanly possible, preventing breakdown and delays in the process.

Military industry

In the military, functionality is paramount. Products designed by TE Connectivity’s DEUTSCH provide consistent performance that won’t interfere with vital services and operations, helping to prevent breakdowns and downtime.

Mining industry

Mining equipment is subject to some of the most extreme and challenging conditions, where dirt, moisture and high vibration is a daily challenge. TE DEUTSCH sturdy, heavy duty and environmentally sealed connectivity solutions fulfil the interconnection needs of this industry.

Off-highway application

Off-road vehicles, such as tractors, backhoes, cranes and bulldozers are all prone to high vibration, moisture and mud, all of which can negatively impact the functionality and performance. By using TE DEUTSCH products, these potentially expensive risks are minimised. TE Connectivity’s DEUTSCH industrial environmentally sealed connectors reputation in the market is why major off-highway manufacturers use TE DEUTSCH.

Industrial commercial transportation

For trucking and transit companies, a poor connection will cost both you and your customers money. That’s why virtually every major truck and bus manufacturer uses TE Connectivity DEUTSCH solutions for their interconnection needs in critical applications.


Dalroad supply a wide range of automotive connectors for nearly all automotive-specific environment applications. We supply world-leading connectivity solutions, designed to be tough and durable in even the harshest environments.
