High-performance horizontal port sensor for small electronics

Fujikura has developed new models of analog semiconductor pressure sensors (temperature-compensated), the AH3 series. Compared to existing sensor models with vertically aligned pressure introducing ports, the new products have a unique outlook with horizontal incorporated introducing ports. This structure helps customers to package smaller electronics or to mount parts to a substrate at a thinner...

2-axis controller with wheel-gear-BLDC motor system

AGV’s need two motors to move and steer.  Compared to the traditional One Motor/One Controller approach, the Dual Channel is simpler, cheaper, safer and easier to integrate and maintain. Two controllers can even team up to drive 4 motors. High efficiency across a range of speedsIncreased battery efficiencyReduced setup timesVersatility in design and performancePlug and Play incl.

Safe Torque Off compliant to SIL3

In mobile robots applications, "Stop" must always mean stop. And "Always" really means always - even if the motor controller is faulty and unresponsive. To do this, a growing number of our controller implement the STO - Safe Torque Off. STO function is compliant to: IEC 61800-5-2:2007, SIL 3 IEC 61508:2010, SIL 3 IEC 62061:2005, SIL 3 ISO 13849-1:2015, Category 3 Level e Product detailsRoboteQ...

There are a large number of applications for which most commercial piezo-resistive MEMS pressure sensors are not suitable. Pneumatic applications are a prime example. Pneumatics always involves a small amount of oil, something that most MEMS pressure sensors don't react well to in the long run. It weakens the Wheatstone bridge as well as the bonding points and sooner or later the sensor will fail....

Almost no offset drift year on year

Piezo-resistive MEMS pressure sensors are known for their effect of exhibiting offset drift over extended periods of time due to technological reasons. To ensure the best performance, the offset therefore needs to be readjusted once fitted and after each application throughout the product life cycle. This isn't an issue for some applications. Under particular operating conditions, the pressure is...
