DCM Sistemes BKL1010A Area Backlight (100x100 mm)

BKL1010A

The BKL1010A has a 100x100 mm active diffusing surface in a 116x106x22 mm housing weighing 305 g, rated IP40 (IP65 available as a factory modifier). It is powered at 24 VDC (PIN1 = +24V +/-3%, PIN2 = 0V) through a 2-pin male chassis connector. In continuous mode (Type C) maximum consumption is 4.8 W white, 7.7 W blue (470 nm), 6.1 W green (525 nm), 7 W red (630 nm) and 10 W IR (850 nm); strobe (Type S) and overdrive/powered (Type i, via the DCM iBlueDrive controller) operating modes are also available, with monochromatic 470/525/630/850 nm, white and RGB LED options.

Technical overview

The BKL1010A is a posterior diffuse backlight: a 100x100 mm evenly diffusing emitting surface that sits behind the part so the camera sees the object as a dark silhouette against a bright, uniform field. This bright-field, back-illuminated geometry is the classic technique for measuring outlines and detecting presence/absence rather than surface texture. Because the light passes around (or through translucent) parts and the diffuser smooths out hot spots, edges resolve as crisp, high-contrast transitions, which is exactly what subpixel edge-finding and blob tools need for repeatable dimensional gauging. It does not reveal surface defects, engraving or topography on the camera-facing side; for that you would use front, dome or low-angle lighting instead. The 100x100 mm window sets the practical limit on part size, so the feature or silhouette you are measuring should fit comfortably inside that active area with margin for part movement.

Wavelength is a configurable choice on this fixture, and it matters for contrast and accuracy. The standard build is white, with monochromatic options at 470 nm (blue), 525 nm (green), 630 nm (red) and 850 nm (IR), plus an RGB variant. Shorter wavelengths such as blue diffract less and tend to give the sharpest edges for precision measurement on a monochrome camera, while red or IR can be useful for shooting through or around semi-translucent materials and for suppressing ambient light when paired with a matching bandpass filter on the lens. The monochromatic versions draw different power in continuous mode, ranging from 4.8 W for white up to 10 W for the 850 nm IR build, which reflects the relative efficiency of each emitter; budget your 24 VDC supply accordingly for the colour you order.

Electrically the unit is straightforward to integrate. It runs on 24 VDC at plus/minus 3 percent (PIN1 = +24 V, PIN2 = 0 V), and the standard continuous Type C version needs no controller at all, you simply switch the 24 V rail. For applications that demand frozen motion or extra brightness, strobe (Type S) and overdrive (Type i) variants are offered, the latter driven by DCM's iBlueDrive controller, which lets you pulse the LEDs in sync with the camera exposure and push them above continuous current for short bursts. The housing measures 116x106x22 mm and weighs 305 g, making it thin and light enough to mount flush in a fixture beneath the inspection plane. The standard rating is IP40, suitable for clean, dry enclosed cells; an IP65 build is available as a factory modifier where washdown or particulate exposure is a concern.

Best for

  • Dimensional measurement of stamped, machined or moulded parts, where the 100x100 mm diffuse field produces a clean silhouette for subpixel edge gauging of width, length, hole position and outline conformance.
  • Presence/absence and completeness checks on small assemblies in electronics production, using high-contrast back-illumination to confirm components, pins or connectors are fitted.
  • Profile and edge inspection of automotive components such as clips, gaskets, seals and small metal parts where outline accuracy and burr detection matter.
  • Fill-level, shape and silhouette verification of packaging items and translucent containers that fit within the 100x100 mm emitting window.
  • Locating and framing parts for traceability/code reading stations, where a uniform backlit field helps segment the part position before a separate front-lit reader captures the mark.

Selection notes

  • Confirm the part silhouette fits inside the 100x100 mm active surface with clearance for handling tolerance and part-to-part variation; for larger parts you need a bigger backlight, this fixture only illuminates a 100 mm square field.
  • Choose the LED colour deliberately: blue (470 nm) for the sharpest edges in precision measurement on a mono camera, red/IR (630/850 nm) for shooting around translucent material or rejecting ambient light, and pair the chosen wavelength with a matching bandpass filter on the lens for maximum contrast and stability.
  • For the standard Type C continuous version no controller is required, just switch the 24 VDC plus/minus 3 percent supply (PIN1 = +24 V, PIN2 = 0 V); if you need to freeze fast-moving parts or boost output, specify the strobe (Type S) or overdrive (Type i) variant and budget for the DCM iBlueDrive controller and camera-synchronised triggering.
  • Size your 24 V supply for the ordered colour, since continuous draw ranges from 4.8 W (white) to 10 W (850 nm IR); the lower-power white build is the simplest to power from a shared rail.
  • Plan the environment around the IP40 standard rating, which suits enclosed, dry cells; if the station sees washdown, coolant mist or dust, order the IP65 factory modifier rather than relying on the standard housing.
