Product catalog summary
Overview: The DF-100 is a rotary electric encoder designed for harsh environments, offering high precision and reliability. It features a low profile, no-contact design, and is resistant to temperature extremes, shock, moisture, EMI, RFI, and magnetic fields.
Mechanical Specifications: The encoder allows for a mounting eccentricity and axial tolerance of ±0.1 mm. It has a rotor inertia of 72,091 gr·mm², a nominal air gap of 0.6 mm, and weighs 126 grams. The dimensions are 100 mm outer diameter, 57 mm inner diameter, and 9 mm height, made from aluminum.
Electrical Specifications: Operates at a supply voltage of 5V ± 5% with a maximum cable length of 1,500 mm. It supports digital interfaces with analog Sine/Cosine outputs and has a current consumption of 180 mA.
Environmental Specifications: The encoder operates within a temperature range of -40°C to +85°C and can be stored between -50°C to +100°C. It has a relative humidity tolerance of 98% non-condensing, shock endurance of 100 g for 11 ms, and vibration endurance of 20 g from 10 to 2000 Hz. It is rated IP 40 for protection.
Performance: The encoder offers an angular resolution of 18-20 bits, with a maximum static error of ±0.015° and extended accuracy static error of ±0.010°. It supports a maximum operational speed of 1,500 rpm and unlimited rotation measurement range.
Interface and Communication: The encoder uses Synchronous Serial Interface (SSI) and BiSS-C Interface for data transmission, supporting clock frequencies from 0.5 to 2.0 MHz and a position update rate of up to 30 kHz. It includes advanced calibration and monitoring options via Electric Encoder Explorer software.
Ordering Information: The encoder can be customized with different cable orientations, mounting options, output interfaces, and resolutions. Optional accessories include a demonstration kit with a mounted encoder and RS-422 to USB converter.

Absolute Position Rotary Electric Encoder - DF-100 Data Sheet-1

ABSOLUTE POSITION ROTARY ELECTRIC ENCODER HARSH ENVIRONMENT The DF-100 is a member of the DF series of Electric Encoders™, based on Netzer precision proprietary technology. The Electric Encoder™ offers many advantages - some unparalleled • Low profile (10 mm) • No bearings or other contacting elements. • High resolution and precision • High tolerance to temperature extremes, shock, moisture, EMI, RFI and Magnetic fields • Low weight • Holistic signal generation 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 ball bearings, 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. 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. • Digital interfaces 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.
