Sensor Cables By Application
We design sensor cables for optimal and stable performance in a wide range of home appliances.
We provide both temperature-sensing cables (fixed or flexible) and door hinge sensor cables (high-flex) for refrigerators. They can survive sub-zero cold without cracking or signal drift.
These cables are built with PTFE or fiberglass insulation to deliver stable signal integrity in high-temperature environments (up to 260°C).
These cables are designed to connect to water level and temperature sensors. They can handle moisture, vibration, and detergent exposure throughout the wash cycle.
For washing machines using ultrasonic sensing, we supply transducer cables to preserve high-frequency signal integrity.
These cables are exposed to strong EMI from inverters and compressors, so we offer foil, braid, or combined shielding to block electrical noise and signal interference.
These cables feature ultra-flexible conductor stranding and space-saving insulation. They can maintain clean signal transmission within confined installation spaces.
Custom Sensor Cables — Stable Signals and Proven Durability
Whether it’s sub-zero cold in a refrigerator or 200°C heat inside an oven, our sensor cables are built to help keep the signal clean. You tell us what you need for wire gauge, connectors, jackets, and shielding, and we make the cable.
Blocks EMI with foil, braid, or combined shielding to ensure stable signal transmission.
Able to withstand tough conditions inside home appliances, such as freezer cold, oven heat, and detergent.
Passes 100,000+ flex cycle testing with no signs of wear.
We test every cable for continuity, dielectric strength, insulation resistance, and short circuits before shipment.
Facilitates routing in complex spaces and simplifies installation.
It can operate for a long time in an environment ranging from -20 ° C to +260 ° C, preventing high-temperature aging.
Work in a high-humidity environment for a long time to prevent short circuits and prolong service life.
It can withstand repeated temperature changes and prevent the insulation layer from cracking.
Sensor Cable Customization
We tailor your sensor cables to your requirements. Conductors can be bare copper or tinned copper, in either solid or stranded configurations. If your application requires continuous flexing, we use fine-strand tinned copper conductors. We also offer multiple insulation and jacket materials, such as PVC for general-purpose applications, TPE for low-temperature environments, silicone for high-heat exposure (up to 200°C), and PTFE for higher temperatures (up to 260°C), covering a temperature range from –30°C to +260°C.
Noise-Free Signal Transmission
ECOCABLES offers noise-free sensor cable assemblies for your home appliances. Where EMI is a concern, we add foil, braid, or combined shielding to keep noise out. Foil shielding is usually used on cables in static applications for high-frequency EMI protection. Braid maintains its shielding effectiveness under continuous flexing. Combined shielding (foil+braid) is preferred when both severe EMI and continuous flexing occur. We choose the right shielding based on your EMI environment and whether the cable moves.

Over 20+ years, ECOCABLES has been designing and manufacturing wiring harnesses for a wide range of applications. Our sensor cables for home appliances are built for stable signal transmission. With exports to the United States, Italy, and other global markets, we are trusted by customers worldwide.
Our factory has more than 200 automatic wire manufacturing machines, including wire cutters/strippers, crimping presses, overmolding machines, and cable testers. Every cable we ship is 100% electrically tested. We guarantee 99% on-time delivery — even the best cable is worthless if it arrives late.
Different Sensor Cable Solutions
Each appliance presents its own cable challenges. We design different solutions to help you eliminate intermittent signal failures and extend the cable service life.
Refrigerators with door-mounted displays and sensors may encounter intermittent door switch signals, ice-maker controls stopping responding, or display screens going blank. All these problems are traced back to the failure of standard door hinge cables (with PVC jackets and solid conductors) under repeated flexing at sub-zero temperatures. To address this problem, we use fine-strand tinned copper conductors for superior flex life, and a TPE jacket that stays flexible at –30°C. Our solution is proven to survive 100,000+ flex cycles in testing.
Washing machines may experience overfilling or not filling at all, which is often traced back to moisture ingress at the sensor cable connector. That is, water seeps in, corrodes the metal pins, and causes the sensor to fail. The standard PVC jacket also breaks down under constant exposure to detergent and moisture. To address this problem, we adopt an IP67 overmolded connector with a rubber sealing ring to block water ingress at the termination point, and use a chemical-resistant TPE jacket that withstands detergent and moisture. Our solution passes rigorous water immersion tests, with no water ingress detected after 72-hour submersion.
The oven sensor cable is exposed to high temperatures, heat radiation, repeated heating and cooling, as well as long-term heat aging. Therefore, it is subject to extremely strict requirements for its heat resistance performance. We select appropriate insulation materials such as silicone, PTFE, FEP, or high-temperature XLPE according to the different temperature ranges of the equipment, and combine them with high-temperature resistant terminals, fiberglass sleeves, and protective structures to comprehensively improve the heat resistance of the line sensor cable. Guarantee steady transmission of sensor signals in high-temperature environments, effectively reduce insulation aging, and protect equipment during safe operation.
Dryer sensors are constantly exposed to high-temperature air, continuous thermal cycling, vibration, and moisture. We select cable materials resistant to high temperatures and thermal cycling to guarantee stable performance under extreme temperature fluctuations. We also design flexible cabling and protective structures tailored to the installation location to effectively protect against vibration and moisture damage. The final dryer sensor cable achieves precise temperature and humidity detection, thereby optimizing the drying control logic.

Sensor cables connect sensors to a control board. They carry low-frequency analog or switching signals, such as temperature or water level readings. Transducer cables, on the other hand, transmit high-frequency signals between the ultrasonic generator and the transducer.
Temperature sensing cables for refrigerators fall into two main types: fixed and flexible.
- Fixed types are designed for sensors inside walls and air ducts. They do not move after installation. PVC insulation is usually used to maintain signal accuracy at sub-zero temperatures (down to –30°Cor lower).
- Flexible types are built for sensors mounted onto doors or drawers. They bend every time the refrigerator door opens and closes. TPE insulation is preferred, so that the cable can stay soft at –30°Cand have a longer flex life.
The typical temperature ratings of sensor cables range from –30°C to +260°C. After reviewing your application requirements, we will select suitable insulation and jacket materials, and customize the cable construction to meet the temperature rating you require for your project.
Stable signal transmission comes down to the right cable design and manufacturing. Signal interference can be suppressed through appropriate conductor structures and EMI shielding. Our quality team electrically tests every sensor cable before shipment and archives test records for traceability.
Connectors can be chosen from XH, JST, Molex, and other widely used connector families. Pin configurations are available from 2 to 20 positions (e.g., 2-pin, 3-pin, 4-pin, and 5-pin) for most sensor cables, and can be expanded for more complex applications. Waterproof connector solutions (e.g., IP67 connector) and M8/M12 connectors are also available.
The MOQ starts from 50 pcs. Prototypes can usually be prepared within 3–7 days. The lead time for small-batch orders is generally 3–7 days, while custom production usually takes about 7–15 days.
