The Avior line includes a set of complementary function devices for use in step verification or servo control systems. These durable components are manufactured with the same high-grade materials and processes with which we make our motors and gearboxes, and are designed to be seamlessly integrated with those components. Standard position modules use either Hall effect sensors, a single-speed resolver or a multi-speed resolver. We are also introducing a new encoder module with no optical read heads and 20-bit resolution. All these position modules are available in simplex or redundant configurations.
