Zettlex electromagnetic induction hollow ring shape absolute encoder

An absolute encoder that, like a resolver, is designed for harsh environments and can achieve 22-bit high resolution and high precision. It is unaffected by condensation, oil, dust, or dirt.

Zettlex Overview and Features - A thin, hollow ring-shaped electromagnetic induction absolute encoder that can be easily and directly mounted on the final mechanical rotating parts such as large-diameter shaft axes. It contributes to improving system-level accuracy without the use of gears or reducers. - Can be directly mounted on shafts with diameters from Φ5 to Φ526 mm. - Maximum resolution of 22 bits (4.2 million divisions per rotation), with output formats including SSI, BiSS, and other serial outputs. - Composed of two ring-shaped substrates for the stator and rotor, it is thin, lightweight, completely non-contact detection, and has a bearingless structure. - The basic principle is similar to that of a resolver, allowing use in harsh environments such as condensation, oil, dust, dirt, and extreme temperatures. Standard products are IP67 rated, with an optional IP69 rating available. - Offers higher resolution (up to 22 bits) and higher accuracy (up to ±19 seconds) compared to resolvers, and does not require external circuits such as AD converters or multipliers. - Due to the 360° full circumferential integration detection, eccentric mounting of the rotor or shaft wobble is always compensated, having no effect on the output. - Not affected by motor magnetic fields. - Achieves high reliability and durability through a simple substrate structure and components. - Ideal for industrial equipment applications such as measuring instruments, manufacturing equipment, chemical and food plants, civil engineering equipment, machine tools, meteorological observation cameras and radars, and robots.
