DCM SAC0505A Diffuse Axial Compact Light

Six wavelength options — 470 nm blue, 525 nm green, 630 nm red, 850 nm near-infrared, broadband white (W00), and RGB — give integrators precise control over contrast. Blue and green wavelengths enhance contrast on yellow or orange substrates and improve character edge sharpness for OCR tasks. Red emphasises surface relief on lighter materials and pairs naturally with red-pass filters to reject ambient light. The 850 nm IR variant is insensitive to visible-spectrum ambient interference, making it reliable on factory floors with variable lighting; its strobe peak current rises to 1465 mA (35 W), roughly double that of the visible wavelengths (615 mA / 15 W), compensating for the lower quantum efficiency of most CMOS and CCD sensors in the near-IR. Continuous mode draws only 3.8–4.2 W at 24 VDC, keeping thermal load minimal in enclosed housings. Strobe mode multiplies effective brightness for short-exposure freeze-motion capture without that sustained heat, though it requires an external VS-series controller. The iBlueDrive mode — activated by the inline ST00 controller connected via the 715 mm aerial 3-pin cable — adds NPN, PNP, TTL, continuous, and dimming control in a single compact inline driver, eliminating the need for a separate DIN-rail controller and simplifying cable routing; in iBlueDrive mode the supply voltage tolerance widens to ±8%, versus ±3% for continuous and strobe modes.

Three operating modes (continuous, strobe, iBlueDrive) give the SAC0505A a broad deployment range. In continuous mode it runs directly from 24 VDC via its 2-pin chassis connector and no external intelligence — the lowest-cost, lowest-complexity integration path, suited to slow-line or triggered-camera setups where the camera's own exposure control is sufficient. Strobe mode demands a VS-series controller but delivers substantially higher peak intensity, enabling very short exposures that freeze motion on high-speed lines while maintaining the low average power and LED lifetime benefits of pulsed drive. iBlueDrive mode sits in between: the ST00 inline controller is compact enough to mount in the cable run rather than in a control cabinet, reducing panel space and wiring, and it supports intensity dimming for fine-tuning uniformity or matching a calibrated reference target. The IP40 housing is suited to clean-room, semiconductor, electronics, and pharmaceutical environments where particulate exclusion matters but liquid wash-down is not required. Operating temperature range of 0–40 °C covers standard factory and laboratory conditions.
