An apparatus (so-called "passive infrared detector") consisting of a printed circuit assembly in a plastic housing with dimensions of approximately 11 × 7 × 4 cm.
The printed circuit assembly is equipped with an infrared sensor, passive elements (capacitors, resistors), active elements (transistors, integrated circuits) and a light emitting diode. It is also equipped with a dual in-line package switch, an anti-tamper switch, a block of screw terminal connectors and an output of semiconductor relay type.
The housing comprises a reflecting surface and a lens.
The apparatus has an output signal of up to 30 V DC, 50 mA.
The apparatus is designed to send an electrical signal to an apparatus, such as an alarm system or an electric door, when a movement is identified by detecting changes in temperature.

Classification is determined by General Rules 1 and 6 for the interpretation of the Combined Nomenclature and by the wording of CN codes 8536, 8536 50 and 8536 50 19.
Classification as an electric sound or visual signalling apparatus under heading 8531 is excluded as the apparatus has no self-contained alarm capability.
Heading 8537 covers boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536. As the apparatus has only components of the same type (two switches of the semiconductor relay type), classification under heading 8537 is therefore excluded (see also the HS Explanatory Notes to heading 8537, exclusion (b)).
Classification under heading 9027 as instruments and apparatus for measuring or checking quantities of heat is also excluded as the apparatus does not measure quantities but only detects changes in temperature for the purpose of automatically activating another apparatus.
The apparatus has the function of an automatic switch and it is therefore to be classified as a switch for a voltage not exceeding 60 V under CN code 8536 50 19.
