Zettlex expands IncOder angle sensor range to 30,000 products
Zettlex is expanding its range of IncOder precision, non-contact, absolute angle measuring sensors to include more than 30,000 different product variants.
The IncOder range enables customers to mix-and-match a range of options so that the final product matches their exact requirements. Zettlex says the range now includes: high- and low-resolution versions (14 to 21 bit options); IP67 integral cable; servo clamp format with plain rotor; 55degC operating temperature option; and mix-and-match rotor and stator mechanical formats.
Furthermore, the IncOder product guide has also been expanded to include more information on installation, zero setting and applicable standards, as well as extra details about manufacturing and quality. This revised guide is available to download at www.zettlex.com/en/store/products/1.
IncOders are precision, non-contact, absolute angle measuring devices that use an inductive technique and may be considered as an inductive encoder. The sensors are suitable for precision measurements in harsh environments such as industrial, military and aerospace equipment - where electrical contacts, optical or capacitive sensors may prove unreliable, or where traditional resolvers, synchros or inductosyns are too bulky or expensive.
Two-part devices
IncOders have two parts, a stator and a rotor, with both shaped like a flat ring. The large bore makes it easy to accommodate through-shafts, slip rings, optical fibres, pipes or cables. The rotor is passive, while the stator is powered and contains all the electronics necessary to receive power and to 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.
As there are no contacting, delicate or wearing parts, there is no need for any periodic replacement, service or maintenance. IncOders are therefore 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; calibration equipment; light- and heavy-calibre weapons systems; targeting systems and range finders; antenna pointing devices and telescopes; packaging and laboratory automation; medical scanners and surgical equipment; cranes and telescopic manipulators. IncOders also have a solid track record in safety-related applications, including airborne equipment and weapons systems.
IncOders are made in the United Kingdom, contain no ITAR-restricted components and do not require an arms export licence unless they are greater than 1000mm in diameter. The new range is available at www.zettlex.com as well as through Zettlex's international resellers.
