Product catalog summary
Overview
The DL-25 is part of the DL series of Electric Encoders™ by Netzer Precision, designed for harsh environments. It offers high resolution and precision, withstanding temperature extremes, shock, moisture, EMI, RFI, and magnetic fields. The encoder is holistic, meaning its output is the averaged result of the entire rotor area, making it tolerant to mounting errors and mechanical wander.

Absolute Position Rotary Electric Encoder - DL-25 Data Sheet-1

Absolute Position Rotary Electric EncoderTM The DL-25 is a member of the DL series of Electric Encoders™, based on Netzer precision proprietary technology. The Electric Encoder™ offers many advantages - some unparalleled • High resolution and precision • High tolerance to temperature extremes shock, moisture, EMI, RFI and Magnetic fields. • Holistic signal generation HARSH ENVIRONMENT DATA SHEET The Electric Encoder™ is unique in being holistic, i.e., its output reading is the averaged outcome of the whole area of the rotor, This feature makes the Electric Encoder™ forgiving to mounting tolerances, mechanical wander etc. The absence of components such as flexible couplers, glass disc, light sources and detectors, along with very low power consumption makes the Electric Encoder™ virtually failure free. The internally shielded, DC operated Electric Encoder™ includes an electric field generator, a field receiver, a sinusoidal shaped dielectric rotor, and processing electronics. General Angular resolution Maximum tested static error Extended accuracy static error Maximum operational speed Single turn absolute position Rotation direction* Adjustable CW/CCW The output signals of Electric Encoder™ are analog Sine / Cosine representing the rotation angle. The digital outputs are obtained by further processing - which may be either internal or external to the encoder. The combination of precision, low profile, low weight and high reliability have made Netzer Precision encoders particularly suitable to a wide variety of critical applications including, but not limited to medical equipment and aerospace.
