Sensors Product Roundup
This week’s Product Roundup highlights sensors from leading connectivity suppliers.
Würth Elektronik’s WSEN-ITDS three-axis acceleration sensor is compact and versatile, featuring a MEMS-based capacitive measuring principle, an integrated temperature sensor that allows sensor outputs to calibrate data directly, four measuring ranges: ±2g, ±4g, ±8g or ±16g, and register settings that support application-specific functionalities for free-fall, wake-up, tap, activity, motion, and orientation direction. Its LGA package measures just 2.0 x 2.0 x. 0.7mm (L x W x H) and is specified for operating temperatures extending from -40°C to +85°C, which makes it ideal for use in high-density industrial applications, such as decentralized measurement data acquisition in IIoT networks. This versatile acceleration sensor also supports predictive machine maintenance, delivering up to 1,600Hz high-resolution data rates for vibration monitoring, and energy-saving, low-power functionality, like recording a single pulse when a switch is touched using power culled exclusively from energy harvesting, and its integrated algorithms make it easy for users to prepare the measured data for application cases, which can hasten application development. WSEN-ITDS sensors are available from stock with no minimum order quantity and are available with both a corresponding evaluation board and intensive design-in consultation upon request.

TDFN8 packages measure 2.5mm x 2.5mm x 0.75mm (L x W x H) while XDFN6 packages measure 1.5mm x 1.5mm x 0.38mm. Both sizes of TSYS03 digital temperature sensors have low thermal mass, which provides a quick response to temperature changes, and are rated for operating and measurement temperatures extending from -40°C to +125°C with a resolution of ±0.01°C. In addition, their operating and sleep current are extremely low (<5μA supply and <0.3μA standby), which makes them especially ideal for use in mobile and battery-powered applications. TSYS03 digital temperature sensors are also rated for an enlarged supply voltage range spanning 2.5–5.5V and a maximum supply current of 400μA and are available with adjusted high-accuracy temperature ranges upon request.
I-PEX Connectors’ ES-Grippers are equipped with its ESTORQ electrostatic capacitance torque sensors, which accurately detect and control torque generated by the revolving motion of various kinds of robots and automated assembly machines and smaller, lighter weight, lower cost, and less complex in terms of component parts than torque sensors that employ conventional strain gauges rather than electrostatic capacitance systems. They also have an integrated microcomputer that negates the need for an outer module for corrective processes. I-PEX ES-Grippers with ESTORQ sensors are optimized for mating connectors and capable of automatically adjusting for precise horizontal and rotational insertion alignment in robotics assembly equipment. ES-Grippers with a standard design are optimized for inserting FPC, FFC, MINIFLEX, and EVAFLEX connectors, while those with a vertical design are optimized for wire-to-board, ISH, and IASLP connectors.

Ainstein launched a new line of radar-based sensor modules designed to track and analyze the flow of pedestrians and vehicles in a variety of situations at CES 2020. The new WAYV product portfolio is currently comprised of three sensors that are all specifically designed to improve safety and performance over existing solutions in static, fixed-mount applications including traffic management, surveillance and security, space utilization, building automation, and other smart city systems. The new WAYV Air is based on 60GHz radar sensing technology, has a compact form factor, offers benefits including low cost and low power consumption, and is ideal for detecting and tracking people in both indoor and outdoor environments. The new WAYV and WAYV Pro are mid- and long-range radar sensors with built-in, high-performance radar processors and proprietary advanced radar processing algorithms that can reliably detect and track vehicles and pedestrians in even challenging light and weather conditions. All three sensors establish offer superior range, resolution, and field-of-view and, unlike existing ultrasonic sensors, can be deployed in ceilings to improve aesthetics and reduce privacy concerns. Each WAYV sensor can also cover a wider area more accurately and reliably provide more data than several ultrasonic sensors working in tandem. In addition, out of respect for public privacy concerns with tracking sensors, WAYV sensors don’t identify specific individuals or employ facial recognition software.
