Phoenix Contact MTKDFECUNI Thermoelectric Voltage Terminal Block Pair

The PHOENIX CONTACT MTKD-FE/CUNI is a specialized terminal block pair used to extend thermocouple equalizing conductors within measuring circuits. These terminal blocks are crucial for maintaining the thermal characteristics of thermocouples, ensuring accurate temperature readings. Constructed with a PA insulating material and a robust screw connection, the MTKD-FE/CUNI is suitable for a wide range of industrial applications where precise temperature measurement is critical. It supports conductor cross-sections from 0.2 mm² to 4 mm² and is compatible with various mounting standards like NS 35/7.5, NS 35/15, and NS 32. Its V0 flammability rating ensures safety and reliability in demanding environments.
