Contact sensors
Contact sensors provide a reliable and precise way to measure physical movements or positions through direct mechanical interaction, using components like wipers or sliders. They offer a simple, cost-effective solution for many applications, delivering consistent performance without the need for complex electronics.
Their direct contact design ensures accurate measurements, making them a trusted choice in various industries. While wear may occur over time in high-repetition or harsh environments, they remain a dependable and widely used technology for position sensing.
Non contact sensors
Non-contact sensors provide a highly reliable solution for demanding applications. By measuring with a separate position marker, they operate without friction, minimising wear and maintenance. This enhances durability and ensures consistent performance, even in harsh environments.
With high IP ratings, they offer excellent resistance to dust, moisture, and contamination, making them ideal for long-term use in industrial and outdoor settings.

Many applications need rotation counters to measure angles beyond 360º. Common low-cost 10-turn potentiometers often fall short in resolution and reliability, while optical absolute encoders are too expensive for many uses.
Optical encoders also need continuous power, losing their count when power is interrupted. Geared rotation counters, on the other hand, can wear out over time.
Novotechnik’s 2800 Series multi-turn rotary sensors provide a practical solution. These sensors use patented NOVOTURN™ technology, based on an advanced giant magnetic resistance effect. They are more cost-effective than optical encoders, maintain high reliability and accuracy, and include additional useful features to meet user needs.

Magnetostriction is the elastic deformation of ferromagnetic materials like iron, nickel, and cobalt during changes in magnetization. This occurs due to shifts in the alignment of magnetic regions called Weiss domains. When exposed to an external magnetic field, some domains align, causing mechanical deformation and generating a torsion wave that travels at 2,800 m/s.
A magnetostrictive waveguide is housed along the measuring path, with position marked by an external magnetic field. A short current pulse interacts with this field, creating a torsion wave. The wave's travel time to a converter is measured and processed into a precise position value, offering a reliable and contact-free measurement solution.
-
Non-contact sensors are increasingly needed for harsh environments with dynamic movements and high contamination levels. They offer long service life, even under mechanical stress, and are durable at high speeds and frequencies where potentiometers would wear out.
These sensors provide standardised electrical interfaces, low power consumption (typically <100mA), and remain cost-effective, making them ideal for demanding applications like engines and agricultural machinery.
-
Advancements in control engineering, microprocessors, and semiconductor technology have led to the widespread adoption of electronically controlled systems across industries. This has driven demand for sensors that are both cost-effective and durable, capable of withstanding extreme temperatures (e.g., -40 to +160°C). These sensors are particularly critical in high-volume applications like the automotive industry.
