Zettlex IncOders inductive encoder expanded range

The Zettlex IncOders non-contact, absolute angle measuring devices range uses an inductive technique and may be considered as inductive encoders. The range has been expanded and covers 30,000 different product variants.

The range includes high- and low-resolution versions (14- to 21-bit options) IP67 integral cable, servo clamp format with plain rotor, -55°C operating temperature option, 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.

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

The stator is powered and the rotor is passive. 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 product.

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.

There are no contacting, delicate or wearing parts, which means no need for periodic replacement, service or maintenance.

The encoders are used in a wide variety of applications including: rotary joints and gimbals, actuator servos and motor encoders, electro-optic and infrared camera systems, heliostats and solar equipment, robotic arms and CNC machine tools, test and calibration equipment, antenna pointing devices and telescopes, packaging and laboratory automation, medical scanners and surgical equipment, cranes and telescopic manipulators.
