What is a Deutsch connector?

Deutsch connector explained: reliable connections for vehicle lighting

A Deutsch-connector is the reliable choice for demanding applications in transport and industry. Designed for performance under extreme conditions, it is widely used under the bonnet, in the chassis and cabin.

With a robust housing made of V0-rated thermoplastic, this connector offers excellent resistance to UV radiation, high temperatures and harsh environmental conditions. The advanced silicone seals ensure reliable protection against dirt and moisture, with a protection rating up to IP68. Furthermore, the Deutsch series supports the size 16 round contact system, with a current capacity of 13 amps, ideal for situations where performance and reliability are priorities.

Why are Deutsch-connectors perfect for vehicle lighting?

Vehicle lighting requires an electrical connection that can withstand shock, vibration and exposure to extreme weather conditions. Deutsch-connectors offer just that. Thanks to their robust construction and high-quality seal, they protect electrical connections from moisture, dust and corrosion, even in challenging environments.

This makes them a reliable choice for lighting applications, such as headlights, rear lights and work lights. Moreover, their modular design makes it easy to organise and secure complex wiring in vehicles. This keeps your lighting and electrical systems functioning optimally at all times, regardless of the conditions.

DT-connector

Deutsch s DT series is designed for applications requiring a robust, reliable connection in demanding environments. These connectors support cable thicknesses from 0.5 mm² to 4.0 mm² and can handle currents up to 13 amps. They are water and dust-tight to IP68, making them ideal for use in agricultural machinery, construction vehicles and other harsh environments. Choose the DT series when you need a powerful, durable solution for lighting, motor control or other electrical components with medium power needs, for example.

DTM connectors

The DTM series is designed for signal transmission and applications where space is limited. These connectors are more compact than the DT-connector series and suitable for cable thicknesses from 0.5 mm² to 1.0 mm² with a maximum current rating of 7.5 amps. Like the DT series, the DTM series offers IP68 protection, making them perfect for use in electronic systems such as sensors, ECUs and other light signals. If your project is all about precision and space saving, DTM connectors are the ideal choice.

Which Deutsch-connector is right for your lighting?

Does your light or wiring harness have a Deutsch-connector? If so, first check which connector series and mating connector are required. The number of pins alone is not sufficient to determine whether two connectors are compatible.

• series : check whether the connection belongs to the DT, DTM or another . Connectors from different are not necessarily interchangeable.
• Matching counterpart: check the housing, the contacts and any coding on the existing connection.
• Number of connections: ensure you select enough connections to accommodate all the light’s functions, such as lighting, an additional light function and mass.
• Power and wiring: check that the terminals and the cable used are suitable for the electrical load.
• Mounting and sealing: use terminals and seals that match the cable size and fit the connector in accordance with the product specifications.

When replacing or upgrading, always check the light’s connection details. A connector that fits mechanically does not, in itself, indicate the function of each PIN. View the available connectors for vehicle lighting or ask TRALERT® for advice when configuring your lighting connection.

PIN versions

There are two different types Deutsch : the male and the female versions. The male Deutsch connector (also known as a connector) has a solid pin as the centre conductor. A female Deutsch connector (also known as a socket) has a centre conductor with a hole in it to allow the male connector to be inserted. In addition to the male and female versions, the connectors are also available with various connections. This means there is always a connection available for your light. The different types are listed below:

• 2 PIN female
• 3 PIN female
• 4 PIN female
• 6 PIN female
• 8 PIN female
• 12 PIN female

Although many people assume that "Deutsch connector" is a reference to Germany, the name comes from Alex Deutsch. However, his connectors have earned such a reputation worldwide that they have become almost synonymous with reliability.

Connection of a Deutsch connector

The correct connection of a Deutsch connector is as follows:

1. Preparing the cables: Strip the ends of the cables to a length of about 5 mm.
2. Fixing the contacts: Place the stripped cable in a metal contact (PIN or socket). Use special crimping pliers to firmly attach the contact to the cable. A correct crimp connection is essential for a reliable electrical connection.
3. Installation in the housing: Push the assembled contacts (with cables) from the back through the Deutsch connector seal until they are level with the front of the connector.
4. Locking: Place the green wedge (also known as wedgelock) on the front of the connector and press firmly until it clicks into place. This wedge provides additional locking and prevents the contacts from loosening.

Did you know that Deutsch-connectors play a crucial role in rallying? During intense races over muddy trails and rocky terrain, they ensure flawless electrical connections even under the heaviest vibrations and shocks.
