Wire heaters are a length of insulated Nichrome wire with crimped copper connectors on each end. Crimped contacts are used because of the difficulty in connecting to Nichrome.

A heater is fabricated by wrapping the wire around a cylinder, being careful to heat-sink the wire over it's entire length. Stycast™ epoxy is often used to provide a good thermal attach; Especially at the ends of the wire.

The wire is often folded over in the middle and wrapped bifilar style so that a strong magnetic field is not created when current flows.

Wire heaters are available in 50 Ohm (5') and 25 Ohm (2.5') versions.

Single-strand Nichrome heater wire is recommended for the fabrication of heaters in cryogenic environments.

• AWG 32 (0.203mm)
• 80% Nickel, 20% Chromium.
• Polyimide insulation rated for operation to 493K.
• 100' (30.5M) Reel.

Cryo-con PW4-36 4-wire Phosphor-bronze ribbon cable features low heat conductivity; making it the optimal choice for four-wire measurements in cryogenic environments.

It can also be used for other purposes including fabrication of heater elements.

• 4-wire ribbon cable.
• Phosphor-bronze, AWG 36.
• Butyral bonding film for easy lead separation.
• Color coded Formvar® insulation.
• Low magnetoresistance.
• 100' reel.
