TRIAC thyristor series improve thermal management for smart homes

Designed for appliances, lighting and controls, an additional five high-temperature Alternistor TRIAC switching thyristors have been added to Littelfuse portfolio.

The thyristors are designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 250V RMS.

The high-temperature Alternistor TRIACs provide easier thermal management, especially in application with limited or no heat sinking. They are also available in mechanically and thermally robust clip-attach packages. Their size allows designers to use smaller board sizes in low power applications, while they ensure higher surge capability to withstand short-duration overload conditions.

They are available in five compact, surface-mount and through-hole packages and extend the Littelfuse TRIAC product line by making high 150 degrees C maximum junction temperature devices available in 600 to 800V with ratings of 12, 16, 25, 30 and 40A.

According to Littelfuse, the combination of high temperature capabilities, space-saving packaging and current rating choices make them suitable for IoT smart home applications that require compact design but without continuous high currents. Typical examples are light dimmers, kitchen and home appliances, tankless water heaters and electric tools.

Littelfuse offers high-temperature TRIACs in TO-220AB, TO-220 isolated, TO-263 (D2-PAK), TO-218 isolated (TOP3 Ins) and TO-218X isolated packages with loop leads. Sample requests may be placed through authorised Littelfuse distributors.

Littelfuse manufactures circuit protection, power control and sensing products. Customers in over 150 countries operate in the automotive and commercial vehicles, industrial applications, data and telecommunications, medical devices, consumer electronics and appliances markets.

Adlink accelerates AI access for industry’s IoT

Adlink Edge IoT software enables industrial customers to access AI and drive real time decision making at the edge, says the company, adding that this optimises operational efficiency

Adlink Edge can quickly and securely connect, stream and control operational data – regardless of what industrial equipment, systems, databases or cloud platforms are already used, says the company. Lawrence Ross, general manager of Software & Solutions at Adlink explained: “Using that data our end-to-end industrial IoT solution enables rapid, real time intelligent decision-making empowered by AI, analytics tools and machine learning . . .  partners and customers can quickly find and use the data . . . whether their objectives are optimising efficiency, predictive maintenance or identifying new business models.”

Target applications are automating warehouse logistics with smart scanning, enabling predictive maintenance, optimising efficiency with machine condition monitoring, machine vision and machine learning, enabling automation and reducing time to market, reducing downtime and optimising efficiency and enabling smart remote monitoring.

No programming is necessary, so Adlink can quickly connect previously unconnected operational equipment, sensors and devices. By tapping into native communication protocols, data can be captured and streamed at the edge. From the edge, this data can then be streamed securely between devices – databases and to the cloud, enabling analysis and easy visualisation to inform decisions and optimise operations in real time.

Adlink Edge is deployed via the company’s innovative Digital Experiments methodology which can include hardware, software and support elements for easy integration with any existing IT and OT system.

Users are also able to benefit from IoT expertise within Adlink’s ecosystem which includes AWS, Microsoft Azure, Google, Thingworx, IBM Watson, FogHorn, Intel and SAS.

Adlink Edge is built upon the Adlink Data River which simplifies complex data network programming and enables data to flow freely, but securely, to and from any cloud analytic platform database and between devices, databases and the cloud.

The Adlink Data River is trusted within the military and aerospace industries to deliver mission critical data securely in real time, Adlink notes.

ADLINK Edge™ also includes the Adlink Marketplace containing apps which are connectors enabling third party services to translate between devices and applications, or devices and peer devices.  Also integrated is the Adlink Profile Builder tool which helps users configure and deploy all the apps to communicate with end-points, devices or applications into the platform deployed across a customer’s ecosystem.

Position sensor is robust for use in robotics and military projects

Claimed to offer more robust performance than existing absolute encoders and better resolution and accuracy than traditional Hall effect sensors for industrial robotics and other demanding applications, the RAMK060 is a rotational absolute magnetic kit encoder from Vishay Intertechnology.

The high precision position sensor uses contactless technology to achieve above 13-bit accuracy, 19-bit resolution, and above 16-bit repeatability, reports Vishay, while maintaining robustness against external magnetic fields, moisture, airborne pollution, vibration, mechanical shock, and changes in temperature. It also has a useful electrical angle of 360 degrees and operates over a temperature range of -40 to +85 degrees C. Higher maximum temperature models are available on request.

According to Vishay, it is suitable for space-constrained applications, due to the rotor and stator kit design, the off-axis design (for hollow shaft mounting), the slim profile of around 6.5mm and weighing less than 55g.

The RAMK060 has an outside diameter of 60mm and inner diameter of 25mm. Several multi-turn variants are available, including connection to a backup battery when system power is off. SPI, SSI, or Biss-C output signals are available.

The RAMK060 is self-calibrating, to compensate for mechanical misalignment

Vishay’s patented design is particularly suited for applications that demand precise and repetitive motion such as arm joints for industrial robots and collaborative robots, steering wheels for automated guided vehicles; and machine tools used in printing, textile manufacturing, and milling.

Samples and production quantities of the RAMK060 are available now, with a lead time of 16 weeks for larger orders.
