THE ORIGINAL PUSH-PULL CONNECTOR LEMO SA - Switzerland Phone: (+41 21) 695 16 00 Fax: (+41 21) 695 16 02 info@lemo.com More than 50'000 connector combinations The modular design of LEMO products provides more than 50'000 different combinations of connectors with a large choice of contact configurations: High and low voltage Coaxial and triaxial Quadrax Thermocouple Fibre optic Fluidic and pneumatic Hybrid Custom solutions Cable assembly Contact your local partner on www.lemo.com Safety IC has pressure sensor inside Chipmaker Elmos has integrated a pressure sensor into its new safety IC E524.40. The device is designed for sensing functions in applications like side airbags and pedestrian protection systems. The sensor detects sudden changes in pressure independent of the average ambient air pressure. Both relative and average air pressure are constantly analysed by the IC. The IC complies with the specifications according to AK-LV29 (VDA) and has been designed in accordance with Functional Safety standard ISO 26262. The pressure sensor and the signal readout circuit identify a dynamic pressure change associated to an accident and communicate it to the PSI5 interface. The diagnostic data of sensor and IC are transmitted as well in order to monitor the system status, thus complying with functional safety requirements. Additionally extensive self test routines are implemented for diagnostic functionality at system start and in operation. Self test capability comprises both the sensor and the IC (analog part, DSP, ROM, and EEPROM). The integrated EEPROM stores calibration data, device ID, and other freely programmable data. The system comes in a modified SOIC20 package. For the assembly of the PSI5 network, Elmos offers the interface components E981.07 and E981.08 (dual and quad channel, respectively). Thus a complete system can be configured with synchronized modules easily and quickly. Elmos www.elmos.com Low-profile CAN board suits small embedded systems Kvaser has launched a CAN add-on board that adds a single, high speed controller area network (CAN) channel to any standard computer board with mini PCI Express capability. Offering silent mode, error frame detection and an on-board buffer, the Mini PCI Express HS small form factor board is ideal for any embedded data acquisition systems, but is particularly envisaged for fleet management. This piggyback CAN board measures 30x51mm, it has a low profile connector that complies with the mini PCI Express standard, which connects via a cable to a DSUB connector (or other type) at the computer housing. With just the CAN communication link itself exposed, this arrangement protects total system EMC performance because all the electronics remain inside the computer housing. In car or truck applications, this can be particularly important. Notably, this add-on board complies with EN 61000-6-2:2005, specifying EMC immunity for industrial environments and also operates over the industrial temperature range of -40 to +85 °C. Other features of this device include a bit rate from 40 to 1000 kbit/s and a CAN transfer rate up to 20000 messages/s. The time stamp accuracy is 25 μs. Kvaser’s free of charge CANLIB SDK can be used to develop software for the Mini PCI Express HS board.
