Reader O f f er To win: iC-Haus’12-bit angular encoder evaluation kit This month, iC-Haus is giving away five evaluation kits for its iC-MH8, a 12-bit angular encoder suitable for brushless DC motors. Worth 204 Euros each, the kits could be used to evaluate the single chip magnetic encoder for controlling a motor by means of an on-axis magnet and generate the position data to be displayed on a PC. The data can also be used to generate the UVW commutation signals. Each package comes with the iC-MH8 evaluation board (iC-MH8 EVAL MH2D) plus the iC-MB43U BiSS to USB-adapter and a PC-compatible graphical user interface. The iC-MH8 position sensor integrates Hall Sensors for scanning a permanent magnet. The chip’s Signal Conditioning unit generates constantamplitude sine and cosine voltages that can be used for angle calculation. The resolution can be programmed up to a maximum of 4,096 angular increments per rotation. The integrated serial Interface also enables the position data to be read out to several networked sensors. It supplies quadrature signals with an edge rate of up to 8 MHz and interpolation can be carried out with maximum resolution at a speed of 120,000 rpm. Check the reader offer online at www.electronics-eetimes.com MRI-compatible rotary encoder comes with 13-bit resolution and 12-bit multi-turn tracking Micronor’s MR330 system is what the company claims to be the world’s first commercially available, magnetic-resonance imaging (MRI)-compatible fibre optic absolute rotary encoder system. The all-optical, non-metallic MR338 passive sensor provides precision absolute angular measurement from 0° to 360° with 13-bit (8192 count) resolution and 12-bit multi-turn tracking . A duplex multimode fibre optic link connects the passive MR338 sensor to the active MR330 controller module installed outside the MRI area. This absolute encoder system is designed for use in functional-MRI research, MRI training phantoms, EMC test facilities and other challenging electromagnetic environments where EMF and RF transparency is required. The controller transmits a burst of light to the code disk in the sensor which accurately modulates the spectral components of the light based on angular position. The position information is imprinted in the optical spectrum of the light and guided back to the controller for the position readout. The sensor requires no electrical power and houses no electronic components whatsoever. The controller’s built-in interfaces include SSI, USB, RS485, RS232, Modbus RTU, programmable digital set points and analog outputs (4-20mA and ±10V). The DIN-rail mount module operates from 24 VDC and supports encoder links extending up to 2500 meters. Micronor www.micronor.com Autofocus 8MP USB 3.0 camera supports uncompressed full HD video streaming e-con Systems has launched the See3CAM_80, part of the See3CAM family of USB3.0 SuperSpeed cameras. It supports video streaming at resolutions of up to 1080p at 30fps and includes an eight megapixel autofocus camera module, the e-CAM80_MI8825_MOD, with an OV8825 CMOS image sensor. The UVC compliant camera is plug-and-play in both Windows and Linux. In Windows, the camera is exposed as a DirectShow device and in Linux, as a V4L2 capture source. The See3CAM_80 supports VGA at 30, 720p30, 1080p30 preview resolutions for high end video recording, video analytics and HD video conferencing applications. e-con is also bringing the full 8 Megapixel still image capture capability to regular PCs for very high resolution imaging applications. Above all, the See3CAM_80 can stream the full 8MP resolution video at around 11fps for applications where full image resolution required, but at a lower frame rate. All the above are uncompressed video and streaming is through the USB3.0 Interface which supports about 5Gbps bandwidth. The See3CAM_80 features an OV8825 CameraChip sensor from OmniVision. e-con Systems www.e-consystems.com Infrared line-scanner provides real-time thermal imaging Ircon’s ScanIR3 series of infrared line-scanners and thermal imaging system includes a choice of eight models that provide accurate, real-time thermal imaging in a wide variety of industrial applications. Combined with Ircon ScanView Pro software, the ScanIR3 scanner is designed for reliability and continuous operation in harsh industrial environments. Its robust housing incorporates standard water-cooling and air purge, and also features built-in laser sighting. A rugged processor box provides universal input and output (I/O) capabilities in the field without the need for an external computer. Unlike point Sensors that measure a single point, the line-scanner measures multiple temperature points across a scan line. Its motorized mirror scans at rates up to 150 lines per second, allowing rapid detection of temperature non-uniformities and hot spots. Rotating optics collect infrared radiation at 1024 points within a 90-degree field of view, and industry-leading optical resolution (up to 200:1) enables detection of smaller temperature anomalies. A two-dimensional image is formed as the material moves across the line-scanner’s field-of-view. The multifunctional ScanView Pro software allows custom configuration of ScanIR3 operating parameters and the display of thermal images and temperature profiles on a standard PC. An optional high-temperature enclosure can protect the scanner from exposure to ambient temperatures up to 1090°C.
