About the AI-SL073-W
The SL073 is a compact spot light for close working distance inspection in space-restricted machines. At 30.5 mm in diameter and 56.2 mm long it slots into gaps a full-size spot light cannot reach, and four opposing M3 mounting points hold it securely once positioned.
The head weighs 49 g, light enough to ride on a moving axis without counterweighting, and a narrow 8 degree lens concentrates the output so a small target stays bright at the short distances the light is built for. An optimised performance to price ratio makes it a practical choice where several lights are needed on one machine.
White light lumen maintenance of L70 at 50,000 hours keeps brightness stable through long production runs, and the anodised aluminium housing with acrylic window is rated IP50 for normal factory conditions and certified to CE, RoHS and IEC 62471. The SL073 range covers white, 470 nm, 530 nm, 590 nm, 625 nm and 850 nm, with additional diffusion and polarization available as light conditioning options.
