POLARIZED CONNECTORS are "socket" type devices and, as such, are made up of male and female pairs, for joining extension cables, connecting lances or pedestals to a specific conduit structure for pyrometry or connecting lances and pedestals to the corresponding instrument. For pyrometry systems, they have polarity, i.e. each conductor has a fixed function in the system, in which its segments cannot be reversed, POLARIZED CONNECTORS, don't let this happen. The connectors have holes of different diameters (in the case of female connectors, normally installed in CARBOMAX (type K), INDICMAX (type S) instruments, or fixed structure sockets), as do the connectors with pins (normally installed at the ends of type K (yellow) and type S (green) cables). This difference in diameter prevents the conductors from being reversed and maintains the functionality, precision and calibration of the system.

The yellow POLARIZED CONNECTORS are type K, normally used in temperature measurement systems from 0ºC (32ºF) to 1320ºC (2408ºF). Their contacts are made from the same alloy as the sensor, so you can extend or join the parts without major loss of thermocouple signal. The red paths of the negative (-) K-type extension cables are installed in the larger diameter pins or holes. The smaller diameter pins or holes are installed in the yellow paths of the type K, positive (+) extension cables. This cable is normally used in Thermal Analysis systems, for example CARBOMAX DELTA.

The green POLARIZED CONNECTORS are type S, normally used in temperature measurement systems between 600ºC (1112ºF) and 1700ºC (3092ºF). Their contacts are made of copper alloy and alloy 11, which act to compensate for the electronic characteristics of type S sensors (these are made of platinum alloys). The red paths of the S-type compensation cables, negative (-), are installed in the larger diameter pins or holes. The smaller diameter pins or holes are installed in the black paths of the positive (+) S-type compensation cables. This cable is normally used in S-type temperature measurement systems, e.g. INDICMAX
