Why Choose TONFUL Data Cable Assembly
Superior Signal Integrity & EMI Shielding
Data loss is unacceptable. We utilize advanced aluminum Mylar foil and tinned copper braided double-shielding techniques to completely isolate your data signals from Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), ensuring flawless high-speed transmission in noisy industrial environments.
Custom Overmolding & Strain Relief
Unlike basic assembled connectors, our data cables feature custom injection-overmolded connectors. This creates an inseparable bond between the cable and the connector, providing unmatched strain relief, superior bend lifespans, and a highly professional, finished look for your final product.
Rugged Jackets for Extreme Environments
We offer specialized jacket materials beyond standard PVC. Choose PUR (Polyurethane) for robotic drag chains requiring millions of flexing cycles, or LSZH (Low Smoke Zero Halogen) for confined spaces like aerospace and rail transport where toxic smoke prevention is critical.
Advanced High-Frequency Testing
You aren't just buying wires; you are buying verified performance. We go beyond basic continuity testing by utilizing advanced equipment like TDRs (Time Domain Reflectometers) and Fluke network analyzers to certify gigabit Ethernet speeds, impedance matching, and crosstalk reduction.
IP67 / IP68 Waterproof Solutions
For outdoor telecoms, marine applications, or factory automation subjected to washdowns, we design and manufacture data cables with threaded M12, RJ45, or USB connectors that guarantee complete IP67/IP68 waterproof and dustproof seals.
Complete OEM Branding & Tooling
We act as an extension of your own brand. Our in-house tooling department can design custom molds to create unique connector shapes, specific angled exits (90-degree), and even emboss your company logo directly into the overmolded plastic for maximum brand recognition.
Professional Selection Guide
Step 1: Define the Data Protocol
Identify what the cable needs to transmit (e.g., USB 3.0 data, Gigabit Ethernet, 4K HDMI video, or low-speed RS485 serial data). This dictates the number of twisted pairs, wire gauge (AWG), and impedance requirements.
Step 2: Specify the Operating Environment
Tell us where the cable will live. Will it be indoors (standard PVC)? Will it be outdoors in the sun (UV-resistant)? Will it be constantly moving in a robotic arm (High-flex PUR)? Will it be submerged in water (IP68)?
Step 3: Determine Shielding Requirements
If the cable runs near power lines or motors, specify Double Shielding (Foil + Braid) to block interference. If it's a short run in a clean environment, an Unshielded (UTP) design can save weight and cost.
Step 4: Design the Connectors & Overmolding
Select the connector types for End A and End B. Decide if you need standard straight connectors, space-saving right-angle (90°) connectors, or panel-mount sockets. Consider adding your custom logo to the overmold.
Step 5: Provide Pinout & Wiring Schematic
Send us your exact wiring diagram. Our engineers will ensure the pin-to-pin mapping is perfectly matched, whether it is a standard straight-through ethernet cable, a crossover cable, or a completely proprietary custom pinout.
Step 6: Rapid Prototyping & Testing
We will produce a "First Article" prototype using our custom tooling. We will run it through our high-frequency testing lab and send it to you for real-world validation in your equipment before giving the green light for mass production.

Frequently Asked Questions
We have compiled some common questions from our clients. If your question isn’t included here, our customer service is always available to help. We’d love to talk with you.
Q1: What is the difference between Shielded (FTP/STP) and Unshielded (UTP) data cables?
Unshielded (UTP) cables have no internal metallic shield and are cheaper and more flexible. Shielded cables (FTP/STP) have an aluminum foil or braided copper layer surrounding the wires. This shield blocks external electrical noise (EMI) from corrupting the data, which is essential in factories or medical facilities.
Q2: Can you mold my company's logo onto the USB or RJ45 connector?
Yes! As an OEM manufacturer, we have our own mold-making capabilities. We can create custom overmold tooling that features your exact company logo, specific colors, and unique ergonomic grip designs.
Q3: What does "LSZH" mean for cable jackets?
LSZH stands for Low Smoke Zero Halogen. In the event of a fire, standard PVC jackets release thick black smoke and toxic halogen gases. LSZH materials produce very little smoke and no toxic halogens, making them mandatory for enclosed public spaces like subways, ships, and aircraft.
Q4: Do you test your custom Ethernet cables for Gigabit speeds?
Absolutely. For custom Cat5e, Cat6, and Cat7 assemblies, we use professional Fluke Network Analyzers to test for attenuation, near-end crosstalk (NEXT), and return loss, ensuring they fully support Gigabit (or 10-Gigabit) data transfer rates.
Q5: What is the Minimum Order Quantity (MOQ) for custom overmolded cables?
If the cable uses standard raw wire and existing connector molds, the MOQ is very flexible. If your design requires a completely custom wire extrusion (e.g., a specific custom color jacket) or a brand new injection mold for the connector, a reasonable MOQ will apply to cover the setup costs.
