Digital CMOS Laser Sensor

The Keyence GV Series Digital CMOS Laser Sensor from Keyence (Woodcliff Lake, NJ) uses a DATUM Algorithm to stably detect targets. The GV is an optical triangulation sensor, and it excels in detecting shiny objects with multiple reflections, as well as light absorbing materials such as black rubber. Designed for automatic, in-line sensing applications, the GV detects target presence or absence based on surface characteristics or target height and provides a GO/NG output. Up to four sets of sensors and amplifiers can be used for each application, and the GV Series includes four IP67 rated sensor head models with detection ranges of 45mm, 130mm, 450mm, and 1000mm.

Thermal Camera

The Jade LR is a high-performance thermal camera from Cedip Infrared Systems (Croissy-Beaubourg, France). The camera provides long-range images from fixed position surveillance applications, including passive observation, detection and recognition of targets by day and night. The Jade LR uses motorized lenses (25, 80, and 320 mm focal length), switchable by a single command, to provide detection or recognition capabilities at distances ranging from 5 to 25 km. It can be remotely operated through a communication line with the video image provided in either analog or digital RS422 format.

Water Repellent Cables

Cicoil (Valencia, CA) has released water-repellent silicone cables that are impervious to immersion, high humidity, fungus, and damp operating environments. Also, extremely dry conditions, low humidity, or salt spray and seawater exposure will not affect the cable’s high flexibility or life. The flat silicone cables are available with wire gauges from 4 to 44 AWG and can withstand temperature extremes from -65 degrees to +260 degrees Celsius. They are available in continuous lengths or as assemblies complete with connectors.

Intensified CCD Camera

Hamamatsu Corporation (Bridgewater, NJ) has introduced the C10054 series of compact Intensified CCD (ICCD) cameras for capturing still images or continuous video of high-speed or ultra-low-light phenomena. Key features include a high-speed electronic shutter that provides a shutter time as short as 5 ns, and image intensifiers that increase available light for detection by the camera’s CCD. Spectral response of the camera ranges from UV to visible to near-infrared. The camera head is equipped with either a TV format-type CCD or a progressive scan CCD and image resolution is up to 480 TV lines. The C10054 is available with three different types of photocathodes.
