Infrared Source Series 12
• Supported, Coil Wound
• Rugged and Reliable
• IR-12 & IR-12R operate at 900 C when powered with 10 watts
• IR-12K operates at 975°C when powered with 11 watts
These popular units have been in production since 1980. They are considered
rugged and reliable. The coiled filament operates at approximately 900: C when
powered with 10 watts for the standard IR-12 and IR-12R sources and 975 C when
powered with 11 watts for the IR-12K. The radiating element is a coil of resistance
wire which has a high emissivity in the Infrared spectral region. The coil is supported
on a grooved cylindrical substrate of alumina, resulting in the windings being
electrically insulated from each other. This contributes to a more uniform radiating
source. The unit does not require operation in a sealed atmosphere. The header is
fabricated from cold-rolled steel. The support pins are hermetically sealed in glass.
The IR-12 Series is offered in several configurations. The standard IR-12 is shown
below. The IR-12R is a standard IR-12 fabricated with the header flange in the reverse
direction. The IR-12 Series also includes the IR-12K which uses Kanthal A-1
resistance wire for higher temperatures.
