Sony Europe’s Image Sensing Solutions has introduced its XCL-SG1240 series of Camera Link V2.0 modules utilizing a 1.1-type global shutter CMOS sensor to deliver 12 MP images at 20 fps. The modules will be available in mass-production quantities from July 2018.
The series, which includes color and black/white modules, further adds to Sony’s award-winning line-up of GS CMOS machine vision modules. Sony has integrated several features including area gain, shading correction, burst trigger and PoCL functions. The cameras are suited to sectors that require exceptional detail even in low (0.5 lx), imperfect or changing lighting conditions. Sony has highlighted intelligent transport (ITS), factory automation, electronics manufacturing as well as AOI / panel inspection as potential applications.
The company has also developed the modules to enable simple migration from CCD systems, allowing for over 1 inch C-mount lens mounts, incorporating the same command control as the XCL-S900 and a Camera Link base configuration. The modules come with both hardware- and software-triggered synchronization, with trigger modes of burst, edge detection and pulse width detection.
The XCL-SG1240 series uses the Sony 1.1-type Pregius GS CMOS sensor. It has been created by Sony’s engineering team to extract the industry’s best image from this market leading sensor. It follows months of Sony ISS engineers working with the Sony Pregius 1.1-type sensor and developing a custom module design that extracts the best possible image quality for the machine vision sector.
The sensor outputs 4,096 x 3,000 pixel images at 20fps (base configuration, 8 bit, 3 tap, Mono/Raw), with full-resolution images being 4,112 x 3,008 pixels. Pixels are 3.45µm2. The modules’ minimum illumination is 0.5 lx (Iris: F1.4, Gain +18 dB, Shutter: 1/30s) and sensitivity is F 5.6 (400 lx, gain: 0 dB, shutter 1/30s). The camera has a signal-to-noise ratio of more than 50 dB and an automatic and manual gain of 0 to +18 dB. Its shutter speed can be automatically and manually configured at 60 to 1/100,000 s, and the color module (XCL-SG1240C) has a white one-push and manual white balance configuration.
A 64-byte, 16-channel user memory has been included and both modules give normal and partial scan readout, with the black/white module also allowing binning. It is powered via DC +12 V (10.5 - 15.0 V) or PoCL (10-13 V) and has an operating temperature of -5 to +45oC. It is available in a 96g, 44 x 44 x 30mm package (W, H, D - excluding protrusions), with a C-mount lens with an MTBF of 64,461 hours.
