Expanded selection of cut-to-length Type J and Type K thermocouple extension wire helps maintain signal integrity when thermocouple signals are required to travel long distances to reach operating instrumentation or PLC input cards. The new wire additions include 20 AWG and 16 AWG sizes with two conductors in shielded or unshielded versions jacketed with extruded PVC and extruded FEP Teflon insulation.
