New sensors for intelligent VC cameras: top resolution and frame rates for high speed applications
E
ttlingen – In its VC Base+ and VC Board Cam lines, image processing expert Vision Components now also employs new 2.2 and 4.2 megapixel sensors from CMOSIS. These sensors provide both high resolution and high frame rates, are very light-sensitive, and deliver an excellent image quality. They feature a global shutter, a fast trigger mode, and a triggered linescan mode that allows for frame rates up to 18 kHz. The CMOSIS-based cameras are therefore suited for use as line scan cameras in high-speed applications. Cameras available with the new CMOSIS sensors are the standard models VC7222 and VC7224, and the board cameras VCSBC6222 nano RH and VCSBC6224 nano RH which feature a remote sensor head. Measuring 2/3 , the 2.2 megapixel sensor can record up to 46 images per second at full resolution (2,048 x 1,088 pixels). By means of a freely programmable ROI setting, it can also support the FullHD resolution of 1,920 x 1,080 pixels, or reach a frame rate of 320 images per second at VGA resolution. Measuring 1 , the 4.2 megapixel sensor provides big pixels and is especially light-sensitive and low- noise. At full resolution (2,048 x 2,048 pixels), it can record 23 images per second. In addition to high-speed tasks, typical applications are industrial image processing, traffic monitoring, 3D scans, motion surveillance, automotive applications, barcode and OCR recognition, and microscopy.

Variohm EuroSensor launch new VLPSC linear position sensors with digital signal conditioned voltage or current output
ariohm EuroSensor’s new VLPSC linear position sensor adds integrated signal conditioning electronics with an autosensing 0 -10 VDC or 4..20 mA proportional digital output in a tried and tested design based on its flagship VLP series potentiometric output sensors. The digital signal conditioner offers a 12-bit resolution with linearity to 0.1% and excellent repeatability in a choice of nine standard measurement ranges from 25 to 290 mm.

Combining the durability of Variohm’s VLP series linear potentiometer position sensor and the convenience of a digital output device, the new VLPSC has self-aligning spherical bearing mounts in a 15 mm square housing design. The new sensor includes the improved O-ring and felt shaft sealing arrangement recently introduced on the VLP series and provides IP65 ingress protection in a compact design that keeps the overall sensor length shorter than competitive devices from other manufacturers. The signal conditioner adaptation also provides a teach function for the start and end datum position references of the sensor which is easily carried out via a simple stand-alone procedure using a separate input

rather than more complex computer programming. The VLP measurement technology used in the new sensor features a conductive plastic resistance element that is built up by the application of several layers of specialised printed inks. This combines with a patented elastomer damped multi-fingered precious metal wiper arrangement that ensures smooth and uninterrupted contact with low electrical noise, even under the most demanding physical and environmental conditions. The VLP series is widely used in arduous application areas such as motorsports as well as agricultural machinery and construction equipment where it enjoys an excellent quality and reliability profile. The typical life of the VLP wiper mechanism is over 25 million operations. The VLPSC has an operating temperature rating of -40 to +90ºC, a supply voltage rating of 24 VDC +/- 20%, and is supplied with 3m leads. Custom versions with alternative stroke lengths, specialised mountings and connectors can be supplied on request.
