HDSERIES HIGH DENSITY MULTIPLE WIRE FEEDTHROUGHS

C

Conax Technologies’ HD Series high density mechanically sealedfeedthrough assemblies allow multiple insulated wires to be installedthrough a single port.These assemblies consist of a stainlesssteeltube swaged over bundled 24 AWG solid Teflon-insulated thermo- couple wire or copper wires.The thermocouple pairs are available withor without junctions.HD assemblies provide an excellentmeans to passnumerous thermocouple,INDUSTRIAL RTD and low voltage instrumentation wires through a vessel wall without breaching the wall in multiple locations.HD assemblies can be supplied with or without a Conax Technologies’“soft seal”gland for pressure/vacuum sealing.When equipped with a gland,the tube passes through the sealing gland,providing a continuous wire feedthrough.Assemblies configured with a PG gland can accommodate up to 60 conductor wires or 30 thermocouple pairs.An MHM gland can accommodate multiple HD assemblies to seal up to 240 conductors or 120 thermocouple pairs.Assemblies can also be furnished with split glands or MK glands.The stainless steel tube is provided with a 4-1/2" nominal lengthstandard.These feedthroughs are normally furnished with 24 inches of leadwire on each end.Longer lengths may be furnished as required.• Temperature Range:-112Ëš F to +250Ëš F (-80Ëš C to +120Ëš C)• Vacuum Rating:5 x 10 • Leak Rate:1 x 10
