Zettlex IncOder range of inductive non-contact encoders

Zettlex IncOders are a range of inductive non-contact encoders designed for measuring absolute angle. The range has recently been expanded to cover 30,000 different product variants. The range includes high- and low-resolution versions (14-21 bit options), and IP67 integral cable, a servo clamp format with plain rotor, and a -55°C operating temperature option, as well as mix and match rotor and stator mechanical formats.

The encoders are suitable for applications that need precise measurement in harsh environments - where electrical contacts, optical or capacitive encoders may prove unreliable or where traditional resolvers, synchros or Inductosyns are too bulky or expensive.

Encoders have two parts - a powered stator and a passive rotor. Each is shaped like a flat ring.The large bore makes it easy to accommodate through shafts, slip rings, optic fibres, pipes and cables.

The stator contains all electronics necessary to receive power and generate the output signals. The output signals from the stator show the absolute position of the rotor relative to the stator right from power up. There is no need for compliant couplings and the rotor and stator can simply be connected to the host system. Precise mechanical mounting is not required and there are no bearings. Operation is unaffected by condensation or dust.  Robust, anodised aluminium alloy housings and monolithic constructions are used for both rotor and stator, and there are no contacting, delicate or wearing parts which means there is no need for periodic replacement, service or maintenance.
