Renishaw, Hoffman Estates, IL, has introduced a 13-bit magnetic sensor for rotary and angular positioning control. Providing 8,192 counts per revolution, the sensors are available in chip, chip-on-board, and ready-to-mount packaged versions. The solid-state, non-contact design features an integrated circuit chip that senses the position of a separate two-pole permanent magnet. Suited for difficult environmental requirements, the sensors provide -40°C to 125°C operational temperature range, and shock and vibration resistance. Friction-less, low-inertia operation enables 0.3° positioning accuracy at speeds to 30,000 rpm. They are available in models providing absolute, incremental, analog, or digital outputs, as well as simultaneous SSI and incremental output. Chip and chip-on-board models allow the sensors to be integrated into machinery and equipment designs. Packaged versions enclose the chip and electronics in metal cases. Enclosed units are used in rugged applications and environments; fully encapsulated versions are waterproof.
