T01102 001229 MTC 6 Thermocouple terminal blocks Thermocouple terminal blocks Spacing 6 mm .238 Compression clamp Entrelec s MTC 6 thermocouple ter- minal block provides an interface for DIN 1 - 3 connecting thermocouple wire with virtually no loss of signal integrity. The interface design ensures positive wire continuity and allows selection and inventory of one terminal block for all thermocouple material. 6 mm block for thermocouple The thermocouple principle is based wires. on the reaction of different metals to temperature. When thermocouple wires are terminated or connected, themetal balanc must be maintained. The introduction of a End stop th. 9,1 mm BADL V0 0199 408.02 foreign material (such as copper) Figure 1.

Universal terminal block Other thermocouple terminal blocks are available with hardware (screws, NFC DIN UL CSA NFC-UTE UL CSA NFC-UTE UL CSA NFC-UTE UL CSA Characteristics clamps and connecting bar) which match the thermocouple material being used. This requires inventory of many different terminal block types.

Thisneutra method of connection limits the introduction of foreign materials to an insignificant level. The thermocouple wire insulation is stripped (31 mm maximum) and the bare wires are superimposed on one another. The thermocouple wires are in contact over their complete 31 mm length and tightened at two points by round tip screws (see figure 2). The screws, made of plated brass, have only a mechanical function, that of holding the wires together with a point contact. Thus, the pressure points are not relevant in the connection environment. One thermocouple lead connects through one terminal block (see figure 2). The MTC 6 requires only 6 mm of space, allowing 50 terminals per foot of rail. Thermocouple shield wire connector bar The MTC 6 can be field or factory equipped with a shield connector bar (see R figure 1). This bar, made of treated brass, mounts in the lower part of the R See section on markers terminal block.
