The 011520622, also known as the MTC 6, is a thermocouple terminal block that provides a reliable interface for connecting thermocouple wires with virtually no loss of signal. This block accommodates two thermocouple conductors with diameters from 0.5 mm to 1.5 mm and has a rated voltage of 500V Gr.C. It requires a maximum wire stripping length of 31 mm and a recommended tightening torque of 0.4-0.6 Nm. The compact 6 mm spacing allows for high-density mounting, with up to 50 terminals per foot of rail, making it ideal for extending thermocouple wire lengths to measurement instruments in space-constrained applications.
