Allegro MicroSystems Announces PCB-Less 3D Magnetic Sensor for Vehicle Safety and ADAS Applications

Allegro MicroSystems announced the A31316 3D Hall-effect position sensor, the latest addition to the company’s 3DMAG™ line of 3D sensors. Offered in an industry-smallest 4 × 4 mm body PCB-less package, this new sensor is ideal for automotive safety and advanced driver assistance systems (ADAS) applications that require high levels of flexibility and reliable performance in harsh conditions such as powertrain and chassis applications, as well as industrial applications that require linear or rotary sensing.

The A31316 3D Hall sensor eliminates the need for a PCB or other external components. This sensor integrates the die and capacitors in a single package to address the need for high-performance, compact position sensors that are robust to these environments. For vibration-robust designs, the A31316 pins can be welded or soldered directly to connector leadframes and can be overmolded or potted for a tight seal. These integration options greatly reduce the ability for contaminants and vibration to affect performance and can bring new design flexibility to spaces where mechanical vibration and contamination are potential issues (more info).
