An economical, practical and reliable heat source
capable of providing uniform heat transfer to flat surfaces.
Mica insulated strip heaters are used in hundreds
of industrial and commercial heating applications.
Specifications and Tolerances
If tighter tolerances are required consult Omega. A heater’s physical size combined with electrical ratings will determine the actual minimums and maximums. Performance Ratings Maximum Sheath Temperature: Rust Resistant Steel: 480°C (900°F) Stainless Steel: 650°C (1200°F) Nominal Watt Density: 5 to 45 Watt/in² (0.8 to 7.0 Watt/cm²) Maximum Watt Density: Depends on operating temperature and heater size; 38 Watt/in² (5.9 Watt/cm²) Maximum when UL and CSA approval is required Electrical Specifications Maximum Voltage: 480V Maximum Amperage: Lead Wire Termination: 10 A Screw Terminations: 8-32UNF—20 A; 10-32UNF—25 A Resistance Tolerance: 10%, -5% Wattage Tolerance: 5%, -10% Material Specifications and Physical Sizes Standard Sheath Material: Rust resistant steel Optional: Stainless steel or aluminum Nominal Thickness: 4.76 mm (3/16") Minimum Width: 15.88 mm (5/8"), may vary depending on termination Width Tolerance: ± 0.79 mm (1/32") Maximum Length: 1829 mm (72") Length Tolerance: Up to 610 mm (24") ± 1.59 mm (1/16") Over 610 mm (24") ± 3.18 mm (1/8") Screw Terminals: 25.4 mm (1") Wide Strips: 8-32 threads Over 25.4 mm (1") Wide Strips: 10-32 threads
