Although there’s an array of position sensors to choose from nowadays, inductive position sensors have become more mainstream in the past few years. They have become the sensor of choice because of its durability and robustness in safety-related, safety-critical or high-reliability applications in a wide variety of industrial, automotive and consumer industries.
IDT's contactless position sensor solutions are magnet-free, significantly reducing materials costs while providing immunity to magnetic stray fields – a mandatory requirement for many applications, particularly in automotive. Instead of magnets, the inductive position sensors interface with low-cost PCB-based coils and simple metallic targets, providing single-chip design flexibility for rotary end-of shaft (on-axis) sensors, rotary side- and through shaft (off-axis) sensors, linear position sensors from short to very long strokes), and arc position sensors (from small angles up to full 360° absolute angle sensing). The devices are automotive-qualified, ISO 11452-8 compliant, and support implementation in safety-related systems compliant to ISO 26262.
However, there are some concerns. A major reason for the relative scarcity of inductive sensors is that it can be challenging for an engineer to provide meaningful designs. With IDT’s newly announced partnership with Thetasys, a technology development company focused on sensors and sensor networks, as a design resource, customers no longer need to be experts on inductive sensors, making it easier for customers to implement reliable and flexible solutions while reducing system costs.
The Thetasys engineering team has more than 20 years of combined inductive sensor design experience and has had wide exposure in overcoming countless application-specific mechanical constraints which create design barriers for engineers new to inductive sensing technology. In addition to experience designing consumer and industrial applications, the Thetasys team possesses deep understanding of the automotive environment and standards, including ISO26262 functional safety. Customers working with Thetasys will not only achieve a robust, producible design while optimizing schedule and budget, but also bring the most competitive product to market.
