PRODUCTS AUTOMOTIVE & MOTORSPORT ROTARY POSITION SENSORS
Curtiss-Wright has launched a new range of shaft-operated, rotary position sensors for OEMs designing vehicles and control systems. With a low-profile sensor body depth of 17.3mm, and using the popular 28mm diameter flanged housing with crush-proof mounting zones, the SRH301 and
SRH302 sensors offer performance against water, dust, shock, vibration and temperature. The rotary position sensors are suitable for use in challenging environments and as a cost- effective solution for medium volume applications where a wide range of options or degree of customisation may be required. The sensors can be powered from either a 5Vdc regulated
supply or from a varying voltage in the range of nine to 30Vdc. All variants of the SRH301 and SRH302 rotary position sensor
use Hall-effect sensing technology to provide a long mechanical life. There is a choice of two shaft configurations, both compatible with existing de facto industry standards for straightforward inter-changeability on existing equipment. The electrical output spans of both models can be set to correspond to rotations of 20° to 360° in one degree increments. Factory- programmable electronics can be set to one of two analogue voltage output ranges or one of three PWM frequencies. Connection options are industry-standard AMP Superseal or
Deutsch DT04 series connectors, or simple 18AWG flying-leads for customer termination. The sensor can also be supplied with a protective NC10 flexible conduit for the cabling.

COMBUSTION ANALYSIS
NEW ECALL
CONFORMANCE TEST SOLUTION
The Kistler KiBox To Go provides a complete combustion analysis system for mobile and test bed applications. Building on its engine testing and
analysis experience, Kistler developed the KiBox mobile engine combustion analysis system, which integrates with other mobile systems for ECU development and diagnostics. The KiBox system is compatible
with PiezoSmart and TEDS (Transducer Electronic Data Sheet) sensor identification to simplify set-up and operation. Automatic plausibility checks guarantee prompt measurement availability and high quality data.

Keysight Technologies’ E6950A eCall conformance test solution simulates a public safety answering point (PSAP) and uses a Keysight wireless test set and RF signal generator to emulate a cellular network to provide global navigation satellite system coordinates. This is required by the in-vehicle system (IVS) to compile the eCall Minimum Set of Data (MSD).
The E6950A eCall conformance
Rohde& Schwarz has developed a universal solution for testing vehicle keys and the associated electronic control units with their various wireless technologies. No matter which technology
the manufacturers of vehicle key systems select, testing requirements in development and production will be high to ensure interference-free functioning. Rohde & Schwarz’s TS7124AS shielded test box provides an interference-free environment for testing devices. The box is equipped with an application-specific DUT mount and adapted antenna systems.
TEST SOLUTION FOR VEHICLE KEYS The central unit is the
CompactTSVP PXI-based test system with an optional embedded CPU. The system manages the precise supply of power to the DUT and measures the supply currents in the various operating modes, even time-synchronised to RF bursts from UWB signals. The system also handles wireline DUT communications such as LIN, CAN, I2C and SPI. An FPS spectrum analyser
evaluates RF signals in the frequency and time domain. A Helmholtz magnetic coil and corresponding 3D magnetic
AUTOMOTIVE GRADE BATTERY MONITOR
Intersil has introduced the ISL78610 12-cell lithium-ion (Li-ion) battery pack monitor. The device provides cell balancing and accurate voltage and temperature monitoring to safeguard Li-ion battery packs in hybrid electric vehicles, plug-in hybrid electric vehicles, and electric vehicles. System designers can use the ISL78610 as a standalone battery-pack monitor or as a redundant back-up device when combined with the ISL78600 multi-cell battery manager. This combination enables automobile manufacturers to

test solution makes it possible to verify that the IVS modem is able to trigger an emergency call, send the correct raw MSD, and establish a voice connection with the PSAP. The test solution also gives developers the option of performing audio analysis. It is capable of supporting current
and legacy wireless test sets, such as the Keysight E7515A and E5515C, thus offering many existing E5515C users a cost-competitive option to repurpose existing equipment. Explaining more about the
field power generator are used to test and calibrate magnetic compass systems. The solution also includes powerful software packages to control test sequences and manage the collected measurement data.

solution, Siegfried Gross, vice president and general manager of Keysight’s automotive and energy solutions business unit, said: “Keysight’s new eCall solution is targeted to help developers in the automotive industry enhance their capability to release conformant and high-quality eCall products, while ensuring fastest time-to-market.”

achieve the ISO 26262 automotive safety integrity level (ASIL) D rating. The ISL78610 monitors and balances up to 12 cells with accurate voltage
readings and diagnostics. This lets system designers make informed decisions based on absolute voltage levels rather than simply receiving a signal indicating an out-of-range condition. The ISL78610 includes a voltage reference, 14-bit analogue-to-digital converter and registers for control and data, while connecting directly to a microcontroller through its 2Mbps SPI interface. The device also offers four external temperature inputs, and includes fault detection and diagnostics for all key internal functions.
