Richards Thermocouple and Temperature Sensor Catalog 16

52 / 204

Thermocouple plugs and jacks are made from thermocouple alloys to insure accuracy throughout the thermocouple circuit.
Types R, S, and C, plugs use compensating alloys. All Richards plugs are made with solid pins to prevent loosening of the con-
tacts. The pins are also polarized to prevent making mismatched connections. The connector bodies are color coded for easy
identification. The pins and jacks are available in standard (with round pins) and a smaller miniature (flat pins) version.
Mounting: Plugs can be mounted on a thermocouple element with a compression type tube adaptor (TA ) and screws,
compression type insert (TAI), crimp insert (CI), or brazing insert (BI). Jacks can also be mounted to extension wire with a cable
clamp (CL). See “Accessories” pages for more details on sizes and types.
Wiring: Standard style plugs and jacks will accept wire up to 20 gauge. Larger gauges such as 14, 11, or 8 should use
the jab style connectors. Miniature plugs can use 20 gauge or smaller thermocouple wires.
