Optical rotary torque sensors
Sensor Technology has launched its digital ORT 230/240 series of sensors. These sensors are ideal for applications that require low torque and/or high bandwidth, as they provide precise, dynamic measurement of rotary and static torque of less than 100nm and for bandwidths of up to 50kHz. The TorqSense ORT 230 series of sensors provides fixed voltage or current analogue outputs – one for torque, and one for either speed or power. The TorqSense ORT 240 series provides two user selectable voltage or current analogue outputs – one for torque and the other for either speed, power or peak torque – plus digital outputs including RS232, CANbus and USB for interfacing with modern instrumentation and laptops.
Multi-layer ceramic chip capacitors
TDK Corporation has developed a new series of vertically stacked MEGACAP Type MLCCs that combine high capacitance and low ESR. The new CA series offers rated voltages from 25V to 1000V and covers a capacitance range from 20nF to 150µF. The new MLCCs are available with C0G, X7T, X7S and X7R temperature characteristics. Thanks to their high capacitance values, the new capacitors are suitable for the resonant circuits of wireless and plug-in charging systems—for example, for industrial vehicles and robots. They can also be used in smoothing and decoupling applications in industrial equipment.
Breakout board for stable voltage
Recom has released a breakout board to connect the SensorTile from STMicroelectronics to Recom’s R-78S evaluation board. This technology enables the SensorTile to draw a stable
3.3V from a AA battery down to voltages as low as 0.65V.
The R-78S3.3-0.1-EVM-1/STM1 breakout board has been designed to be used with an STMicroelectronics STEVAL STLCS01V1 SensorTile module, and the R-78S3.30.1-EVM-1 evaluation module has been developed to demonstrate IoT applications using the SensorTile module. When powered directly through a coin cell battery, the input voltage can soon drop significantly after only a few hours of use. This causes the Bluetooth Low Energy transmission unit to stop operating reliably and wastes the energy from the coin cell battery.
