An absolute encoder that, like a resolver, is designed for harsh environments and enables 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 final mechanical rotating parts such as large diameter shafts. It contributes to improving system-level accuracy without the need for gears or reducers.
- Can be directly mounted on shafts with diameters from Φ5 to Φ526mm.
- 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 circumference integral detection, eccentric mounting of the rotor or shaft wobble is always canceled out, 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.
