The CTT2.5UK is a K-Type thermocouple terminal block specially designed for accurate temperature signal transmission in industrial temperature measurement systems, instrumentation panels, process control applications, and automation systems. This terminal block is engineered for use with K-Type thermocouple compensating cables (Chromel / Alumel), ensuring reliable temperature signal continuity and minimizing measurement errors in industrial environments.
In temperature sensing applications, maintaining thermocouple signal integrity is extremely important. Standard terminal blocks can create unwanted junction potentials, which may lead to incorrect temperature readings. The CTT2.5UK solves this issue by using current-carrying elements made from the same material as K-Type thermocouple wire, helping preserve thermoelectric continuity throughout the circuit. This ensures precise signal transfer from the sensor to the measurement or control device.
The CTT2.5UK is widely used in industries where accurate temperature monitoring is essential, such as furnaces, ovens, heat treatment plants, process industries, chemical plants, food processing units, power plants, HVAC systems, and industrial machinery. It is designed to maintain stable and accurate temperature signal transmission even in electrically demanding industrial environments.
This terminal block features a 4 screw clamp connection design, allowing secure conductor retention and stable electrical contact. The screw clamp mechanism ensures vibration-resistant wiring, making it suitable for industrial environments where equipment movement, continuous operation, and thermal stress can affect electrical connections.
The DIN rail mounting design allows easy installation in industrial control panels, temperature instrumentation cabinets, PLC systems, and automation enclosures. Its compact structure helps optimize panel space while keeping wiring neat and organized. The terminal block is also clearly marked for K-Type thermocouple identification, helping reduce installation errors during field wiring.
Manufactured using high-grade Polyamide 6.6 insulation material, the CTT2.5UK provides excellent dielectric strength, heat resistance, and mechanical durability for long-term industrial use. The housing protects against accidental contact and ensures safe operation in harsh environments.
The CTT2.5UK supports wire sizes from 0.2 mm² to 2.5 mm² (22–12 AWG) and offers a 10A current rating with 300V voltage rating, making it ideal for industrial thermocouple measurement circuits. The compact dimensions of 10 mm width, 45 mm height, and 43 mm length make it suitable for space-efficient panel installations.
With its K-Type thermocouple compatibility, secure screw clamp design, DIN rail mounting, and reliable signal transmission, the CTT2.5UK is an ideal solution for temperature measurement professionals and industrial automation engineers.
