See our new M12 cables which include M12 thermocouple connector pins and socket materials, please see the M12CM Series
These thermocouple extension cables utilize field mountable M12 connectors (uncompensated) along with a wide variety of stranded thermocouple grade cables
and the full line of Omega's popular thermocouple connectors to provide an unlimited selection of cable assemblies tailored to fit your specific
application. When one of our standard M12C Over-Molded Thermocouple Cables simply won't provide the needed connection, these cables are just what is needed.
To configure your cable, simply determine the following information:
The thermocouple extension cables include stranded thermocouple grade (or better) conductors with the standard insulations being PFA (TT) and PVC (PP).
Note: The same insulation material is used for both the conductor insulation and over jacket. For dual element cables two individual cables are provided, one to each
thermocouple set as shown in the table below.
These cables are the same as those used in our wide variety of thermocouple sensor products.
Since our M12 enabled thermocouple sensors all utilize a plug style connector, you will most likely need a socket style connector to attach the cable to the sensor. These
connectors are available in either straight (SFSR) or right angled (RFSR) configurations. Please note the following wiring information:
M12 Connector Pin Number
Type J ANSI
Type J IEC
Type K ANSI
Type K IEC
Note: For single TC cables only pins 2 and 3 are connected as shown above. For dual T/C cables, one cable connects to pins 2 and 3 and the other cable connects to pins 1 and 4 as shown above.
The process connection can vary from stripped leads (FL), to another M12 style connector to one of the many styles of thermocouple connectors for which
Omega is well known. Some of the most popular include straight M12 male connector (SMSR), right angled M12 male connector (RMSR), full size thermocouple
connector (OSTW) and the miniature thermocouple connector (SMPW).
The final requirement is the length of your cable. Omega specifies the length of the cable in meters. Our standard selection of cables are provided in 3, 5, 10,
15 and 20 meter lengths, but you can specify a length longer or shorter then this. The length of the cable is simply listed on the end of the model number.
Omega has selected a number of these cables to be available as standard configurations, they are listed below. Also, there are additional special options such as
external steel braid or armored hose that can be specified, please see the listing at the end of the product table.
† All amounts shown in EUR, GBP, or USD Note:
#20 and #24 AWG stranded conductors same price (note: PVC insulated cables are only available in #24AWG, PFA insuated cables are available in both #20 and #24AWG) .
For longer cables, change last number in model number to the desired length in meters and add the following to the price: for "TT" cable add $2 per meter, for "PP" cable add $1.25 per meter.
For steel braid on the "PP" or "TT" cable, add '"SB" to the end of the cable callout and add $2.50 per meter to the price. For BX hose, add "BX" to the end of the cable callout and add $2.50 per meter to the price.
To add a connector to the "FL" end of the cable, replace "FL" with the following and add the price shown:
For a miniature connector, add "SMPW" at no additional cost.
For a full size connector, add "OSTW" at no additional cost.
For the following M12 connectors add $10 each: straight plug "SMSR", right angled plug "RMSR", straight socket "SFSR", right angled socket "RFSR".
