SPECIFICATIONS
- Mini 3-Pole
Thermocouple Connector plugs and jacks provide rapid, dependable
connections between small diameter sheathed thermocouples and
extension wires with shield terminals an integral part of the
system. In its all-copper version the 3-pole mini is ideal for
3-wire RTD applications.
- The thermocouple
alloys of the prongs and inserts match ANSI standards to maintain
thermocouple integrity. The thermocouple alloy-type letter code,
polarity and shield terminal are identified by symbols that
are molded into the connector body.

Polarized
pins are virtually impossible to mismate.
Large double-wipe
jack inserts assure tight grip and low signal loss. With an isolated
screw design, contact is all thermocouple alloy from wire entrance
to wire exit.
Jab-In® terminals require only 1/4" of insulation to be removed. Wire
is sandwiched between contacts of thermocouple alloy without damage.
For use in
corrosive environments, gold or nickel plated prongs and inserts
are available. Caution - system errors can result from use
of plated contacts if significant thermal gradients exist at the
connector.
Connector
bodies are molded from glass-filled thermoset compounds (will
not melt) for high strength and dependability. The color coded
connector bodies will withstand ambient temperatures to 400°F
(205°C) continuous duty and 500°F (260°C) intermittent use.
High temperature
connector bodies (all high temperature connector bodies are
color coded RED) are made of a highly
stable and inert silicone-based thermoset compound that will withstand
ambient temperatures to 800°F (425°C) continuous duty and 1000°F
(540°C) intermittent use. These units have proven durable in the
presence of radiation, and their low-outgassing properties also
make them highly satisfactory for use under vacuum.
Surface mounting
and stacking, if required, can be made by use of molded-in clearance
holes.
Shield terminals
provide isolated connections of the shield circuit via the built-in
sheath-to-shield link.
