Deutsch (TE) Wire Harness

Deutsch (TE) wire harness with braided sleeving

Professional manufacturer of Deutsch (TE) connector

Deutsch, founded in 1938, is an American maker of harsh-environment connectors. Its DT series became standard for trucks, tractors, boats and construction machines. TE Connectivity acquired Deutsch in 2012, so Deutsch (TE) harnesses retain the original design under the TE brand. QL-Custom Technology Ltd., a custom harness, cable assembly and overmolding manufacturer, builds every Deutsch connector harness per your drawing, BOM or sample. Our engineers review all designs pre-production, and finished harnesses get circuit-by-circuit testing. A two-pin lead receives the same care as large multi-branch looms. We also supply matching connector parts, so one team manages your full order.

Deutsch (TE) Connector family

Deutsch (TE) connector & wire harness core series

Every project starts differently. Some buyers need loose connector parts for their lines. Others want finished Deutsch (TE) harnesses plugging straight into machines. Many need new designs. We cover all three. Deutsch housings, contacts and wedgelocks are stocked, ready to build.

Standard Deutsch (TE) Connectors

Need parts for your own assembly line? We supply standard Deutsch receptacles, plugs, contacts, wedgelocks and seal plugs. Popular DT, DTM and DTP sizes are kept in stock in 2- to 12-way configurations. Parts ship loose or packed as kits. Each lot carries clear part numbers. If a housing is hard to find, we will help you find it.

Finished Deutsch (TE) Wire Harness Assemblies

Some teams just want a part they can install right away. For them, we build finished harnesses, pigtails, jumpers and extension leads with Deutsch plugs on one or both ends. Each Deutsch connector cable assembly is tested before it leaves our floor. Labels and part numbers follow your drawing. It arrives ready to plug in.

Custom Non-Standard Harness & Connector

A catalog part will not fit every design. We build harnesses with mixed connector brands, unusual lengths, special wire and overmolded ends. Custom breakout points are no problem. If all you have is an old sample, we can study it and rebuild it to spec. You approve a drawing first, so the finished part matches what you expect.

Deutsch (TE) wire harness Tailored Solutions

No two machines face the same conditions. A harness on a highway truck is exposed to road salt and engine heat. One on an excavator gets hit by rocks and blasted with high-pressure water. For this reason, we design each Deutsch wiring harness for the place where it will be used. Before we draw anything, we look at current, wire length, bend points and nearby heat. We also ask how often the plugs will be opened for service. Only then do we pick the series, wire type, sleeving and routing. You get a Deutsch (TE) wire harness that fits the first time and keeps working when conditions get rough.

Automotive & Refitting

Trucks, buses, vans and off-road vehicles commonly use Deutsch plugs for lights, sensors and accessories. We manufacture engine, chassis, lighting and trailer harnesses for OEM and aftermarket clients. Refit & upgrade kits account for much of our output: LED light bars, winches, work lights and camper power systems. Our plug-and-play harnesses fit vehicles without cutting original wiring.

Construction Machinery

Excavators, loaders, cranes and road rollers operate amid dust, mud and vibration. Their harnesses withstand rocks, hydraulic oil and pressure washing. We supply cab, engine, boom, valve harnesses for such equipment. Deutsch DT and DTM plugs serve most signal and control circuits. At bulkheads and cab-chassis joints, HD30 and HDP20 connectors route multiple circuits via one sealed plug.

New Energy Equipment

Electric machines and energy systems need tough low-voltage wiring. We build Deutsch harnesses for battery management, charging stations, energy storage cabinets and solar trackers. These carry control signals, sensor data and auxiliary power. For rising current, we use DTP and DTHD series with larger contacts and thicker wire. Electric forklifts and construction machines use this sealed design.

Industrial Automation Control

Factory and outdoor machines need wiring that is easy to service. Pumps, compressors, generators and wash-down food machines all gain from sealed quick-disconnect plugs. Control, sensor and solenoid valve harnesses come with Deutsch connectors on each end. When a part fails, a technician can unplug it and fit a new one without rewiring. Contacts can also be pulled and replaced with a simple tool.

Advantages Deutsch (TE) connector and harness

Harsh Condition Resistant & Rigorous Quality Assurance

Most Deutsch series work from -55˚C to +125˚C and keep their seal against water, dust and heavy vibration. Our job is to build every harness so it keeps that rating. Crimps are checked for height and pull force, and each finished harness is tested circuit by circuit. A Deutsch (TE) wire harness from QL-Custom is ready for pressure washing, road salt and long days in the sun.

Custom Deutsch harness with braided branches

Full Customization & Original Universal Compatibility

Our harnesses plug straight into the Deutsch parts already on your equipment. Housings, keys and pin positions match the original part numbers. You choose the wire, length, color, labels, sleeving and connector ends. We can build with original TE Deutsch parts or with compatible parts, based on your budget and approval needs. Either way, every custom Deutsch wire harness is made to your drawing.

Factory Direct Supply, Low Failure & Cost Optimization

Buying straight from the factory takes the middleman out of your price. You talk directly with the engineers who plan your parts and the team that builds them. Our checks catch crimp, seal and pin faults before shipping, so fewer problems reach the field. We also look for honest savings. On high-volume jobs, for example, stamped contacts can cost less than solid ones and still do the job well.

Matching Deutsch Series to Current, Size and Pin Count

DTM

Up to 7.5 A

Made for tight spaces and signal lines. Its size 20 contacts are rated at 7.5 amps each, and housings run from 2 to 12 ways. Pick DTM for sensors, switches and small control modules.

DT

Up to 13 A

The Deutsch series you will see most often. Its size 16 contacts handle up to 13 amps, with the same wide range of housing sizes. It covers most lighting, sensor and general power circuits.

DTP

Up to 25 A

More power in a small body. Size 12 contacts can handle up to 25 amps in 2-way or 4-way housings. Use it for pumps, fans, heaters and motor feeds.

DTHD

Up to 100 A

A single-pin plug for heavy current. Contacts go up to size 4 and are rated up to 100 amps. It suits battery links, starters and main power lines.

HD30

Metal shell

A round, metal-shell connector for high pin counts. One plug can mix different contact sizes. Choose HD30 when multiple circuits must pass through a single sealed bulkhead.

HDP20

Plastic shell

A lighter plastic version of the round heavy-duty plug. It packs many circuits into one housing at a lower cost. Use it where weight and budget matter, but sealing still counts.

الصناعات والتطبيقات

Agriculture and Forestry

Tractors, sprayers, combines, forest machines work in rain, mud and chemicals. Deutsch (TE) harnesses seal lights, sensors, controls through long seasons. Plugs reopen for service. Farm makers and dealers use our harnesses for builds and repairs.

Marine and Offshore

Saltwater reaches every part of a boat. Sealed Deutsch plugs keep moisture away from pumps, lights, engines and navigation parts. We can use tinned copper wire to slow corrosion. These harnesses suit fishing boats, yachts, ferries and port equipment.

Mining

Mining trucks, drills and conveyors run nonstop in dust and heavy shock. Harnesses here need thick sleeving and strong strain relief at every plug. Our Deutsch builds withstand rock impacts and fine dust. When a part fails, crews can unplug it and swap it fast.

Rail Transit

Trains and track-maintenance vehicles need sealed underbody connections. Deutsch harnesses link brake sensors, lights, doors and track gear. They resist vibration, water spray and wide temperature swings. Clear labels let rail crews speed up scheduled maintenance.

Emergency Specialty Vehicles

Fire trucks, ambulances and police vehicles carry extra lights, sirens and control panels. All of it has to work the moment a call comes in. We build upfit harnesses with Deutsch plugs for quick installs. Upfitters save hours on each vehicle.

Motorsport and Racing

Race cars need light, tight wiring that won’t come loose. Deutsch DT and DTM plugs are a common choice in this field. We build compact Deutsch (TE) wire harnesses for engines, dash panels and data loggers. Each one is made to take heat and hard landings.

Field-Proven Build Methods for Harnesses

Deutsch DT plugs and receptacles with sealed leads

Match seals with wires and block empty cavities

We measure wire insulation carefully to select proper suitable seals: thin wires create tiny water gaps while thick wires may tear soft rubber seals. All unused cavities are fully fitted with tight sealing plugs, since open holes easily cause serious connector flooding inside housings.

Use correct crimp tools and fully seat contacts

Solid and stamped electrical contacts require separate dedicated crimp tools and must never be mixed together. Improper crimps may visually look good but unexpectedly fail later in service. Insert contacts fully until they click and pull lightly to confirm; loose contacts lead to hard-to-trace intermittent open circuits.

Install wedgelock flush with housing

The wedgelock must snap flat firmly against the housing face and be visually checked carefully by trained inspectors for every single electrical connector plug. A partially locked wedgelock lets internal pin contacts slip easily under continuous harsh mechanical vibration.

Maintain straight wire run right after the seal

Keep wires straight for a short length after exiting the plug before bending the cables freely in operation. Sharp tight bends directly behind the plastic connector will gradually pull the integrated seal open and lead to unwanted moisture ingress issues later.

Add strain relief and design drip loops

Strain relief including boots, backshells, heat-shrink tubing and clamps takes tension off crimps. Deutsch (TE) harness bends along the cable instead of at the plug. Drip loops are marked on drawings for upward-facing plugs to divert water away.
