Double Conductive Shielding

The Optex FX-40 is an indoor, wired passive infra-red (PIR) motion detector featuring multi-focus optics and a 40' x 40' coverage zone.

The FX Series is designed to provide stable and reliable detection in the most hostile of environments, where many other detectors struggle to function. The highly accurate and reliable detection pattern maintains its sensitivity throughout the detection area even in high temperature or low contrast environments such as conservatories.

Multi-Focus Optics

Normally, a detector uses twin elements create two detection zones but Optex's detectors create an extremely high vertical zone density, two or three times the size of that in conventional PIRs. These taller zones capture the entire body mass of a person and enable detection of the smallest temperature contrast between them and the background.

If a person is hidden from the PIR detector, he or she is not detected. In ordinary residences and offices, there are desks, shelves and other furniture. When these objects hide a part of the body, it may make detection difficult. MultiFocus Optics solve this detection challenge.

Sealed Optics

The pyroelectric element's field of view is fully enclosed by the sealed optics mechanism of the lens, cover and the sealed optics foam. This mechanism prevents insects from crossing in front of the pyroelectric element. The sealed optics also protect against draft through wiring holes. Easy knockouts reduce extra space between holes and cables, further enhancing the sealing of the entire housing.

Spherical Fresnel Lens Design

Spherical lens provides a precise focal length to each of the multiple lens segments (uniform distance between each lens segment and the pyroelectric elements). This enable each lens segment to face precisely towards its detection area, and creates detection zones without distortion, achieving a new level in lens design precision.

The spherical fresnel lens differs from the conventional flat fresnel lens in that the distance between the lens and the pyro-electric elements is the same across the entire lens (the focal length is always the same). It therefore collects infra-red rays more efficiently.

Each focused image (detection zone) has sharply defined edges (=accurate sensitivity) and it produces the maximum signal contrast against the background area (=high detection performance). This sharp focus provides the maximum signal power to the detector, compared to a weak, sluggish signal created by a poorly focused zone.
