Netzer precision motion sensors have taken a revolutionary position sensing technology originally developed for specialised applications in harsh environments, and made it available for today’s broader range of defence, homeland security, aerospace and instrumentation motion control requirements. Standard and customised rotary and linear electric encoders are also used in space, avionics, medical and automotive applications among others.
Providing exceptionally accurate, high resolution, absolute position with miniature to wide diameter hollow shaft, Netzer’s rotary electric encoders are available with Analog Sin/Cos , Digital SSi and Digital AqB+I outputs, and feature up to 20-bit resolution (with 12 bit A/D) and accuracy to <0.01°.
The Electric Encoder’s non-contact technology relies on interaction between the measured displacement and a space/time modulated electric field. It offers a blend of features unequalled by optical or magnetic encoders.
Key advantages of Netzer’s rotary electric encoders include a simple, robust structure with virtually no-failure mechanism; generous mounting tolerances; very low weight, inertia and profile (=<10mm); ring shaped, hollow shaft with a wide range of diameters; absolute position output over 360° rotation range; precision to 0.001° in selected models; default operation range from -55°C to +125°C; dual and triple redundancy options; and no magnetic signature.
Benefits also include high tolerance to condensation and contaminants; insensitivity to EMI/RFI and magnetic fields; high customisability; low power consumption; ultra-high-speed options; and a wide variety of position feedback protocols.
Models range from 25mm OD to 248mm OD (6mm to 170mm ID).
