OMEGA®duplex extension grade
thermocouple wire performs
continuously at temperatures to
105°C (220°F). The wire’s flexibility
permits installation in conduit and
wiring trays, and it is easily stripped
by hand or using mechanical
methods. Insulation is PVC. The
wire is UL listed for Power Limited
Tray Cable (PLTC) applications.
Note: Overbraiding wire invalidates UL rating.

Spool Pricing Guidelines
Multiply 300 m or 1000' spool price by
multiplier and round to the nearest dollar.
Consult Sales for price quote.
7.5 m or 25' = Price from Chart x 0.0625
15 m or 50' = Price from Chart x 0.1
30 m or 100' = Price from Chart x 0.175
60 m or 200' = Price from Chart x 0.3
150 m or 500' = Price from Chart x 0.5
300 m or 1000' = Price from Chart x 1.0
