DCM Sistemes PRL0802A Line Light Projector

Electrically the projector is deliberately simple. It runs directly on 24 VDC (+/-3%) in continuous mode with no external controller, wired through a 2-pin chassis connector (BN/brown = +24 V, BU/blue = 0 V). That means it drops onto a standard machine 24 V rail and turns on with the cell, removing the cost, panel space and timing logic of a dedicated lighting controller. The trade-off is that this model uses a direct continuous LED drive with no iBlueDrive or hardware strobe, so for line-scan work you control effective exposure through the camera's line rate and integration time rather than by pulsing the light. Power draw depends on colour, from roughly 18 W on the IR variant up to about 30 W on white, blue and green, with red around 22 W; budget supply and any heat dissipation around the higher figure if you choose the brighter visible colours. The IP40 rating, 0 to 40 C operating window (0 to 60 C storage) place this as a clean, climate-controlled-line product rather than a washdown or hot-zone fixture.

Wavelength is selected by suffix, and that choice does most of the imaging work. The unit ships as White (W00) for true-colour and broadband capture, Blue 470 nm and Green 525 nm for finer detail and contrast on appropriately coloured or textured surfaces, Red 630 nm as an efficient general-purpose monochrome option, and IR 850 nm where you need to see through certain inks or coatings and suppress ambient visible light. The part number encodes the choice (for example PRL0802A-850C for IR 850 nm continuous). Pair a monochrome line-scan camera with the matching narrow-band colour and a band-pass filter and you get a clean, high-contrast single-line image; pair the white variant with a colour camera for print and label verification. For matrix (area-scan) cameras the same fixture serves as a low-angle dark-field bar to expose surface defects that disappear under flat front lighting.
