Surface-mount infrared sensors lower profile to 2.6mm

Murata has introduced surface-mount pyroelectric infrared sensors for duties including intruder detection, reducing package overheads and total size compared to conventional can-type sensors, as well as enabling high-speed automated assembly.

The Murata IRSA200ST01-R1 has a 5.7mm x 6.7mm footprint and 2.6mm profile, enabling a compact solution. The 4-terminal package also integrates the optical filter and output FET as well as the sensing element, thereby eliminating several external components.

In addition, the IRSA200ST01-R1 delivers high sensitivity and signal-to-noise ratio, stable output over a wide temperature range, high stability against white light, and enhanced RFI immunity. Changes to the shape of the detector element have enhanced stability over temperature, improved detection throughout a wider field-of-view, and increased immunity to false triggering by small bodies such as pets.

A revised lens design also produces greater intensity of light at the detector surface, and several lenses are available to optimise performance for 3m-5m, 5m-7m or 10m-12m detection ranges.

 

FEATURES Field of view: 100° by 100° Operating voltage range: 2V-15V Operating temperature range: -40°C to 70°C
