K-Type (NiCr-Ni) Teflon Thermocouple Cable 2x0.50 mm² is a temperature measurement cable with PFA insulation and a PFA outer sheath for use in K-Type thermocouple measurement circuits. It transmits the thermoelectric signal generated by the sensor to a temperature controller, indicator, data logger, PLC system, or control panel.
The two-core cable has a 2x0.50 mm² cross-sectional area and combines mono/solid thermoelement conductors with PFA fluoropolymer insulation. The PFA core insulation and outer sheath are designed for industrial measurement applications requiring resistance to temperature, moisture, and chemical exposure.
This product is not a standard power cable. It should be used to establish or maintain the measurement circuit with the correct thermoelement structure. For accurate measurement, the cable must be compatible with the K-Type thermocouple and the positive-negative core polarity must be maintained throughout the connection.
The positive and negative thermoelement conductors of the cable are separately insulated with PFA Fluoropolymer. The PFA outer sheath around the cores reduces the direct contact of the insulation layers with the external environment by turning the cable into a single measurement line.
PFA insulation is preferred in industrial temperature measurement cables due to its wide operating temperature range, resistance to chemical effects and low-friction surface properties. The thin and solid conductor structure of the cable helps establish regular connections in fixed installations and applications with limited installation space.
Mono / solid conductors have a single-wire construction. While this structure provides consistent terminal connections in fixed connections, it requires additional consideration of installation conditions in applications with constant movement, intense vibration or frequent bending.
This K-Type thermocouple cable uses color coding that complies with IEC 60584-3. In a K-Type measurement circuit, the green-insulated NiCr conductor indicates the positive (+)and the white insulated NiAl conductor is negative (-) connection.
The cable's outer sheath is also green. This makes the cable easier to identify as belonging to a K-Type thermocouple circuit during installation, maintenance, and troubleshooting.
Thermocouple cables may have different color code systems such as IEC, ANSI and JIS. For this reason, the same K-Type thermocouple cable can be produced with different core and outer sheath colors depending on the standard used. When choosing a product, not only the thermocouple type but also the color standard used in the current system should be taken into account.
The measurement principle does not change between K-Type cables that use different color standards, provided that their thermoelement alloys are the same. The difference is the colors used to identify the positive and negative conductors. During connection, no action should be taken based solely on core color. The thermocouple type, polarity markings, and device terminal diagram should be checked together.
K-Type thermocouple cable enables the measurement line between the sensor and the measuring instrument to be established with the K-Type thermoelement structure. Choosing the cable type compatible with the sensor and device helps reduce measurement deviations that may arise from different metal combinations at the connection points.
The 2x0.50 mm² construction offers a balance between terminal connectivity and mechanical strength in industrial temperature measurement circuits. When selecting the cross-sectional area, the wiring distance, terminal size, installation space, and thermocouple connector should be considered together.
PFA insulation and outer sheath provide advantages in applications requiring resistance to high and low ambient temperatures and chemical effects. The low-friction outer surface can make it easier to route the cable through appropriate channels and transition points.
The green and white cores are easy to distinguish, facilitating polarity checks during connection. The green outer sheath makes it easier to identify the cable as part of a K-Type thermocouple circuit in control-panel and field wiring.
PFA Fluoropolymer core insulation and outer sheath structure are suitable for industrial measurement applications that require temperature and chemical resistance. According to the manufacturer's technical data, the cable is suitable for continuous operation between -90°C and +260°C and for short periods at +280°C.
PFA outer sheath helps protect the cable structure in working environments requiring moisture, chemical contact and low-friction surfaces. In applications with UV exposure, usage conditions and exposure duration should be evaluated by taking into account the manufacturer's technical documentation.
When determining the actual operating conditions of the cable, the temperature value of the insulation material must not be the only consideration. Ambient temperature, mechanical movement, vibration, chemical contact, wiring route, connection points and the terminal or connector used should be evaluated together.
In the K-Type thermocouple circuit, the positive and negative conductors must be connected to the correct terminals. In this product green core indicates the positive (+)and the white core indicates the negative (-) connection.
Reverse polarity may cause the measurement value to change in the wrong direction or the indicator to decrease as the temperature rises. The positive and negative terminal markings on the controller, indicator or PLC should be checked before connection.
When making the connection, use a cable, terminal, and thermocouple connector compatible with K-Type. The use of standard copper cable, cable of a different thermocouple type or unsuitable connection elements may cause deviation in the measurement circuit.
Due to its mono/solid conductor structure, the cable should not be stressed on routes with constant movement or frequent bending. The cable must be protected from sharp edges, crush points and direct flame contact.
Thermocouple cable should be carried on a route as separate as possible from power cables, motor supply lines and inverter outputs in facilities where electromagnetic noise sources are present.
