The Style MTA5 is a mineral-insulated (MI) cable thermocouple assembly with a gasketed connection head rated for harsh environments, available in aluminum, Bakelite, or cast iron. It supports single (2-wire) or duplex (4-wire) configurations and offers exposed, grounded, or ungrounded junctions for varying response times and chemical resistance. Sheath materials include Alloy 600 (2150°F), 304 SS, and 316 SS (1650°F), with diameters from 0.063" to 0.375". Conduit connections are 1/2" NPT for standard heads or 3/8" for miniature and medium aluminum variants. Sheath lengths up to 99 inches are standardized, with tolerances specified by O.D. and length. Compatible with ANSI thermocouple types J, K, E, T, N, R, S, and B.
