The TE Connectivity MTC6.EX 1SNA146227R2500 is a grey Ex-rated thermocouple terminal block from the ENTRELEC SNA range, designed to extend thermocouple conductors while maintaining signal integrity. Its universal design makes it suitable for different thermocouple types, providing a practical DIN rail connection point for temperature-measurement circuits in industrial instrumentation and process-control systems.
The MTC6.EX accepts two rigid thermocouple conductors from 0.9 to 1.5 mm² and uses dependable screw-terminal connections. It has a standard operating voltage of 500 V AC, while the Ex e version is rated at 550 V in accordance with IEC/EN 60079-7. The compact terminal has a 6 mm pitch and one connection position, helping conserve DIN rail space in densely populated instrumentation panels.
Designed for industrial environments, the MTC6.EX features a polyamide housing with a UL 94V-0 flammability rating and operates across a wide temperature range of -55 to +110 °C. It mounts on G32, TH35-7.5 or TH35-15 DIN rails and uses a specified tightening torque of 0.4 to 0.6 Nm for secure thermocouple conductor termination.
Thermocouple circuits require careful conductor handling because unwanted junctions and unsuitable connection methods can introduce measurement errors. The MTC6.EX is specifically designed to provide a practical connection between rigid thermocouple conductors, allowing the thermocouple circuit to be extended while maintaining the integrity of the temperature-measurement signal.
Its universal thermocouple design reduces the need to stock multiple terminal variants for different thermocouple configurations. Combined with its compact 6 mm width, DIN rail mounting and Ex e electrical rating, the MTC6.EX is particularly well suited to instrumentation and process-control panels where dependable temperature signals and efficient panel utilisation are important.
