Our D-Sub cable assembly provides the most powerful and accurate
signals in all places. They offer smooth and secure connections.
You can simultaneously use them for various projects.
Our D-Sub cable assembly (DB9 (DE9) serial cable) is a well-known
and straightforward way to connect. It has a 9-pin D-shape plug.
It is often used for RS-232 serial links between computers and
gear like modems or sensors. The DB9/DE9 plug is small, with 5
pins on top and 4 on the bottom, and was common on older PCs.
These cables give quick and safe plug-in links for serial ports.
Each pin is shielded to cut noise and help steady data flow. With
complete shielding and a metal shell, our DB9 plugs block
interference and last longer. The body and strain relief hold the
D-Sub cable assembly tight and stop bending or pulling damage. We
also mark each cable with transparent labels so installers know
which line. This makes work faster and prevents mistakes.
DB9-to-terminal-block cables make wiring very simple with no
special tools. They have a DB9 plug on one end and a screw
terminal block on the other. You can attach each of the nine
signal wires to a screw. This stops the need for soldering or
crimping. It makes setup in the field quick and easy. The terminal
block holds wires tightly even when vibrating, so the link stays
good. With the DB9 plug's metal shell and screws, you get a strong
and low-care serial link for machines. We also offer terminal
blocks with extra covers for wet or dusty areas. We can supply
longer screws or different colors for each contact to make the
work easier. This gives you more choices for quick changes and
upgrades. You can see all wires clearly and check each one fast.
DB25 Serial Cable
The DB25 serial cable has a 25-pin D-shape plug to carry many
lines. Its bigger shell holds up to 25 wires, first made for
printer ports or multi-line RS-232. Today, DB25 cables serve old
systems and gear that need more lines than a DB9 can give. Each of
the 25 wires is shielded and covered. This provides a steady
two-way link for complex data or parallel use. Its metal shell and
screws lock it in place for a safe, low-noise link. We also add
molded backshells to block dust and moisture. The inner drain wire
keeps the ground solid to reduce hum. We can change the wire size
or jacket for remarkable work to meet high-heat or fire-safe
codes. This makes each DB25 cable ready for many types of work and
safe in many places.
DB25 Connectors
The DB25 connector is a strong D-shape plug with 25 pins (13 on
top, 12 on bottom). It is used for parallel ports and many-pin
serial links. In older PCs, DB25 ports were for printers or
modems. It has many pins, which allow it to carry many data or
control lines simultaneously. Like all D-Sub plugs, the DB25 has a
metal shell that shields all around. The shell also makes sure the
plug only fits one way. Screws hold it firmly to its port. These
parts give the DB25 excellent electrical safety and a strong build
for tough use. You can quickly spot the correct part and connect
it fast.
Material recommendation
Insulated Electronic Wires
We use top insulated wires in all cables for high work and safety.
The wires are multi-strand copper for good flex. All cables are
color-marked or labeled for easy finding. We ensure electric work
and long life by matching the correct wire to the job. We can also
add shielding foil, braid, or drain wires to improve performance.
With all these options, you get safe and easy cables to install
and service, giving you peace of mind and simple use.
Terminal Blocks (Housing)
The terminal block housing in our cables is made of rigid plastic,
such as polyamide or polycarbonate. These plastics give excellent
electrical insulation and high strength. They meet fire safety
rules. Each block holds wires with screws or springs inside,
providing a solid end. Some blocks are modular, so you can add
more poles easily. We advise blocks with seals or coats to stop
rust in wet or harsh places.
D-Sub connectors
We make D-Sub connectors built with care and follow safe rules,
and they can be used for many jobs in many places. The outside
shell is made from a potent mix of metal and is coated with
nickel. It keeps the noise outside and protects the core of the
wire. These harnesses are used in many sectors to flow the signals
to many essential systems. With these cables you can securely
connect the plugs to other ones.
Solution
We make custom cables for many needs. Whether you need small
serial links or mixed video and data, our cables deliver. Each one
is built to your needs. We ensure every D-Sub cable assembly works
right, from small custom orders to large runs. Our engineers help
you pick the proper cable type, plug layout, and protective parts.
We also offer fast turnaround for special builds.
Here is our strong D-Sub plug design. Each plug has a molded
metal shell (often zinc or aluminum with a nickel coat) for a
shield and a rust block. Inside are 9, 15, 25, or more gold pins
(type-based) for steady electric links. We offer cable-mount and
panel-mount versions. Each plug has screws to lock it in place
to stop slipping out. Many plugs also have molded backshells or
hoods. These add strain relief and block dust. Custom types can
also have seals or extraordinary mixed power and data inserts.
We can even make hybrid connectors with signal, power, and coax
all in one shell. This saves space and makes complex systems
simpler. Our vast range lets you pick the exact connector you
need for each job. This makes building your system easy and
quick.
DVI Cable
This part shows a DVI cable assembly for clear video. DVI plugs
send digital video (and analog with DVI-I). If needed, our
cables can change between DVI and standard VGA (DB15). We use
top wires and gold contacts to support high resolution. The
cable is twisted or coax shielded for each channel and clock,
with a braided cover to block noise. This gives clear, stable
video on LCDs or projectors. In multimedia setups, this DB15 VGA
D-Sub cable assembly lets old VGA screens work with new graphics
cards. We can also offer long-run DVI cables with boosters or
ferrite cores to keep the picture sharp over distance. This is
useful in classrooms, control rooms, or events where displays
are far from sources. You get bright, sharp images even when
cables are long.
Micro D-Sub DB9 Cable
Our Micro D-Sub DB9 cable is a miniature version of the standard
DB9. It uses a smaller shell but still has 9 contacts. The body
is about one-third more petite but stays entirely RS-232 ready.
This small form is excellent for tight spaces, like handheld
tools or dense racks. Even though it is small, the micro plug
gives the same screw lock and shield as a complete DB9. We use
fine wires and molded strain relief, so these mini cables last
long and easily fit even in cramped spots. We can also supply
right-angle plugs or ultra-thin jacket versions for less space.
This lets you place cables behind panels or inside small devices
without strain. It makes your setup neat and straightforward.
Custom Configurations Designed
Every system is different, so we make cables to fit each need. We
can change the wires' length, thickness, and shield type around
them. To save space, we can also make cables that carry power and
data in one connector. Wires can be marked with colors or labels,
making them easy to connect and install. We can make flat,
panel-mount, or cables with quick-release plugs. Splitters and
adapters can be built to match special jobs as well. Each custom
D-Sub cable assembly is tested before large runs to ensure it
works correctly and gives safe results.
Our cables are built to keep signals safe, clean, and clear. We
use shielding around the wires to block noise, and twisted wires
to stop crosstalk between lines. We add extra covers for cables
that carry both power and data, so signals do not mix. This design
keeps data fast and safe. Each D-Sub cable assembly is tested to
ensure low loss and smooth flow. This means clear and steady data,
sound, video, or power every single time it is used.
We follow the essential rules to make the harnesses always secure.
All of our parts are UL-approved and follow RoHS and CE safety
rules. We also meet auto and plane standards for safe use in
transport. Each D-Sub cable assembly is tested for bending,
pulling, heat, cold, and shock. These tests show the wires are
secure, strong, and ready to use in many hard places.
D-Sub cables connect robots, machines, sensors, and controls on
the work floor. Their strong metal shells protect the signals
inside from noise made by motors, welding, and other machines.
This makes sure that machines work together smoothly and without
errors. They can last long and be plugged in and out many times
without breaking. They are also easy to remove and replace, so
factories do not lose much time when a repair is needed.
Telecom and Networks
Many older telecom devices still use DB9 and DB25 ports. D-Sub
cables connect modems, routers, and other setup tools. They
carry data and control signals when faster lines like Ethernet
are unavailable. Many service tools still use RS-232 ports with
D-Sub cables for testing and updates. The shield around the
wires keeps signals safe and clear even on long lines, which
makes them very reliable for network work.
Cars, Trucks, and Transport
D-Sub cables are used in cars, trucks, trains, ships, and
planes. They connect sensors, test units, and control systems.
These cables are made to work in hot, cold, and shaky places.
Many have strong shells that stop rust and block water and dirt.
They follow auto and air safety rules, so signals and power stay
safe even in motion. Repair shops also use them to connect test
tools that scan cars for problems.
Hospitals and Labs
For the essential systems in the hospital, these cables are used
to supply the signals properly. They are made under strict
health rules and checked carefully to ensure they work right
every time. This makes them trusted in places where safety is
most important.
Defense and Space
For defense, military, and space jobs, we make robust and safe
D-Sub cables. They are sealed so that dust, water, or sand
cannot escape. The backshells keep the cables locked in place,
even when there is a lot of shock or heavy shaking.
Home and Office Devices
Many older home and office devices still use D-Sub cables. Old
VGA screens, printers, and game controllers often use them. Our
cables help keep video, sound, and data precise for these older
uses. They are also a low-cost way to connect old computers and
devices still in use. Many hobby users who like older gear also
use them to keep their systems running well.

We have made many special D-Sub cable assembly projects for
different clients. These include waterproof cables for outdoor
use, Y-split cables for labs, bendy cables for robots, and tiny
cables for hand tools. We can also make large connectors like DB37
or DB50 for large systems. Each project is designed with drawings
and sample cables before complete runs. All of them are tested
with the same careful steps, so they can be trusted in real use.

and strong even after long use.
Alex Johnson
These cables worked so well in our machines. They came on
time, matched our orders, and were easy to install. The
connectors locked tight, and the shield kept the signal clean
even with other machines running nearby. We ran them for many
hours, and the signal stayed steady.
