November 6, 2019 - Zettlex position sensors (IncOders) use non-contact, inductive technology for precision angle measurement. Zettlex sensors use printed circuits. This enables position sensors with no contacts. IncOders are suited to environments where potentiometers, optical or capacitive devices may prove unreliable.
IncOders have 2 main parts – a Stator and a Rotor – each shaped like a flat ring. The large bore helps to accommodate through-shafts, slip-rings, optical-fibres, pipes or cables. The Stator is powered and the Rotor is passive. The Stator contains the electronics to receive power and generate an output signal. The output signal from the Stator shows the true absolute angular position of the Rotor relative to the Stator without the need of any motion.
IncOder inductive angle encoders do not require compliant or special couplings and the Rotor & Stator can simply be screwed to the host product. Precise mechanical mounting is not required and there are no bearings. Whereas optical or capacitive angle encoders can be unreliable in harsh conditions – notably with condensation or dust – Zettlex angle encoders are generally unaffected by foreign matter and IP67 rated versions are available. Unlike capacitive devices, there is no need to earth the Rotor or Stator. Hard-anodized aluminium alloy housings and monolithic constructions are used throughout. There are no contacting, delicate or wearing parts, so there is no need for periodic replacement, service or maintenance. In other words, IncOder angle encoders are true ‘fit and forget’ devices.
