Wire wound, 1" x 5", 25 watts, 120v, 5 w/sq. in, 8" leads

Wire-Wound Silicone Rubber Heaters

Silicone rubber heaters provide dependable performance under rigorous conditions. Ambient temperatures down to −80°F and up to 500°F do not diminish performance. These heaters can be designed and fabricated in many configurations to fit the size and shape of almost any application requirements.

Features

• Long life
• High reliability
• Versatile configurations
• Flexible for flat or curved installations
• Able to withstand extreme ambient temperatures

Construction

The excellent dielectric properties of silicone rubber and the strength of fiberglass combine to produce a unique heater. First, fine nickel-chromium alloy wire is spiraled onto a center core of fiberglass twine, producing a strong, flexible heating element. Electronically-controlled precision winding equipment ensures consistency.

Circuits are then hand-wound on permanent tooling, providing repeatability of resistance and pattern. Parallel circuits are utilized where possible, permitting continued operation should a single circuit be damaged.

When the heating element is positioned, a second layer of silicone rubber is laid over the wire. The layers are then vulcanized to permanently position the circuits.

Note: These heaters take up to 1–2 weeks to ship.
