Heason Technology has signed an agreement with the UK manufacturer Zettlex Limited for sales and system integration of its IncOder non-contact, inductive angle encoders. The IncOder has gained an enviable reputation for highly reliable precision angular position measurement in extreme environments, and complements Heason's customised motion system design and build service that includes production of actuators and positioning systems used in arduous application conditions. These include the extreme temperatures and pressures found in, for instance, oil and gas and marine industries for down-hole drilling and subsea equipment, as well as the mechanical shock conditions experienced in heavy industrial machinery and aero and defence motion systems. Heason sees the IncOder as a partner for the highly durable KBM servomotor range from its key distribution partner Kollmorgen, and for servo feedback for Elmo Motion's ExtrIQ range of servo motion components for harsh environment applications.
IncOder's non-contacting inductive technology is said to build on this highly dependable measurement principle with new levels of reliability by employing an encapsulated printed circuit design with flat ring-shaped rotor and stator components rather than a traditional wire-wound construction. The many benefits include compact size with simple bearing-less installation that does not require precise mechanical alignment. Furthermore, with no delicate or wearing parts, IncOders yield essentially unlimited life: they also endure very high levels of shock and vibration and, unlike optical, potentiometric or capacitive sensors, are mainly unaffected by condensation or debris. These characteristics combine to make them well suited to servo feedback applications in exactly the kinds of specialised motion system tasks in which Heason Technology excels - from oil-filled actuators for pressure compensation, to laser ranging positioning equipment used in the extremes of Arctic and desert conditions for wind farm evaluation.
The range is available in eight ring sizes with external diameters between 75 and 250mm and with angular resolution from 10 to 22 bits. Each size option includes a wide choice of mechanical interfacing, and a generous internal diameter permits feed-through of cables for slip rings and sensors or other services. The 5, 12 or 24V DC powered stator has integral communications output options that include 0-10V analogue, A/B/Z pulse, digital + 1V sin/cos and SSI (synchronous serial interface). A choice of electrical interfacing options covers standard or flexi cable both with or without connectors, or integral axially-mounted connectors.
