Series 30 – IR30 and IR-35 Coil wound 4.2 Watt TO5 Mounted Infra-Red Emitters These IR sources are coil-wound, supported IR Sources, mounted on TO-5 headers. They are appropriate for use in lab or field instrumentation due to their long life and stable properties. IR-35 – the IR-30 with parabolic reflector The IR-30 Series of IR sources are coil-wound, supported IR Sources, mounted on TO-5 headers. At steady state, the coiled filament operates at ~950°C when powered with 4.2 watts (2.5 volts, 1.7 amps). They can be pulsed up to 1 Hz with a greater power input. When operated at 1 hertz, 50% duty cycle with 3.5 volts, 7.1 watts, the output is a well defined saw tooth with approximately 32% modulation depth. This product is available as the IR-30, without reflector, and the IR-35 which has a parabolic reflector to collimate the energy. Operation in a controlled or sealed atmosphere is not required. For higher modulation speeds, the Series 50 IR sources should be considered. Scitec Instruments Ltd Bartles Industrial Estate North Street Redruth Cornwall TR15 1HR United Kingdom t. f. i. e.
