Test Dedicated Shielded Wire: Cut Interference, Get Accurate Readings
Test dedicated shielded wire
Field measurements live and die by signal quality. A crack in a dam wall, a millimeter of settlement—if noise creeps into your sensor loop, you might miss it. That's where a properly shielded wire makes the difference. At Kingmach, we've spent years building geotechnical instruments, and we know the headaches of chasing phantom signals across a construction site. Our test dedicated shielded wire is designed to tackle that. It pairs a tight-twist conductor layout with a continuous foil and braid shield, keeping electromagnetic interference out of the signal path. Whether you're hooking up piezometers, inclinometers, or crack meters, the wire stays flexible enough for field routing and rugged enough to survive conduit pulls. We stock common gauge sizes and connector pinouts, and we'll cut custom lengths when standard reels don't fit your site. No inflated claims—just a straightforward cable that helps your sensors report what's actually happening underground.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach Measurement & Monitoring Technology Co., Ltd. has been supplying geotechnical instrumentation for projects ranging from metro tunnels to tailings dams. One piece that often gets overlooked—until a crew is tracing a noisy signal at 2 a.m.—is the signal cable. Our test dedicated shielded wire is built for exactly that: linking sensors to readout units with minimal signal degradation. The standard construction uses stranded copper conductors for flexibility, an aluminum/polyester foil wrap for 100% coverage, plus a tinned copper braid for toughness and low DC resistance. The jacket is black PVC rated for outdoor exposure, with ripcord-assisted stripping to speed up field termination. We keep multiple AWG sizes in stock, typically 22 and 24 AWG, in 2- and 4-conductor configurations. For projects requiring specific connector types—Lemo, M12, or bare tinned leads—we can terminate the wire in-house and ship pre-assembled harnesses. As a mid-range supplier with a global distributor network, we focus on practical solutions: fast turnaround on custom orders, technical support that understands field conditions, and compatibility with our own sensor lineup as well as third-party instruments. Whether it's a single monitoring station or a kilometer-long stretch of instrumented tunnel, our shielded wire helps keep your data channels clean and consistent.

FAQ
Common technical questions
What's the difference between regular shielded cable and one that's 'test dedicated'?
Test dedicated shielded wire typically has tighter tolerances on capacitance and shield coverage, which matters when you're measuring microvolt-level sensor outputs. It also uses materials that resist hydrolysis in high-humidity borehole environments, something a generic audio or industrial cable may not handle well.
Can I use this wire with sensors from other brands?
Yes, as long as the conductor count and pinout match. Kingmach's shielded wire follows standard color codes and stripping lengths. If you're interfacing with a specific data logger or readout unit, we can advise on connector crimping or provide pre-terminated assemblies.
Do you offer custom lengths and labeling?
We do. You can order by the meter with no minimum length, and we can print custom markers or color codes on the jacket. This helps a lot when you're pulling multiple cables in a single conduit.
How does the wire hold up in extreme temperatures?
The standard jacket is rated for -20°C to 80°C continuous use. For colder or hotter environments, we can source fluoroelastomer or silicone jackets—just mention it when you inquire, and we'll check feasibility.
What's your typical turnaround for custom wired assemblies?
Turnaround depends on current order volume and connector availability. We'll give you a clear lead time when you send your specifications. Often it's a matter of days for simple pigtails and a couple of weeks for complex multi-pin overmolded connectors.
