Note: The products referenced above represent the most popular constructions. Other constructions can be manufactured to meet individual specification and application requirements.

 
Inner shield 
All above thermocouple wire and thermocouple extension wire can be finished with a inner shield (Stainless steel-SSB, Tinned copper-TCB). If you need the wire with a inner shield, please add "SSB or TCB" to the order code, such as "JX-FB-SSB-FB-20S", it means Type JX, 20AWG, Stranded, Insulation: Fiberglass, Inner shield: Stainless steel, Jacket: Fiberglass 

Outer shield 
All above thermocouple wire and thermocouple extension wire also can be finished with a metal outer shield to give added protection from abrasion and mechanical damage. If you need the wire with a outer shield, please add "SSB or TCB" to the order code, such as "JX-FB-FB-SSB-20S", it means Type JX, 20AWG, Stranded, Insulation: Fiberglass, Jacket: Fiberglass, Outer shield: Stainless steel
