DF-60

Product catalog summary
Overview: The DF-60 is a rotary electric encoder designed for harsh environments, offering high precision and reliability. It features a low profile, hollow shaft, and no contacting elements, making it suitable for various industrial applications.
Mechanical Specifications: The encoder allows for mounting eccentricity and axial tolerance of ±0.1 mm, with a rotor inertia of 10,154 gr·mm² and a total weight of 40 grams. It is constructed from aluminum and has a nominal air gap of 0.6 mm.
Electrical Specifications: Operates at a supply voltage of 5V ± 5% with a maximum cable length of 1,500 mm. It supports digital interfaces and has a current consumption of 180 mA.
Environmental Specifications: The encoder can operate in temperatures ranging from -40°C to +85°C and can be stored between -50°C and +100°C. It has a shock endurance of 100 g for 11 ms and vibration endurance of 20 g from 10 to 2000 Hz, with an IP40 protection rating.
General Performance: Offers an angular resolution of 18-20 bits, with a maximum operational speed of 1500 rpm and unlimited rotation measurement range. The encoder's direction is adjustable, and it includes optional built-in test features.
Interface and Communication: Utilizes Synchronous Serial Interface (SSI) and BiSS-C Interface for data transmission. The encoder acts as a slave in these protocols, transmitting data according to the master clock. The output signal is differential RS-422 with a clock frequency of 0.5 to 2.0 MHz.
Cable and Accessories: The encoder uses 30 AWG twisted pair cables with a braided shield and silicon rubber jacket. Optional accessories include demonstration kits with mounted encoders and RS-422 to USB converters.
Ordering Information: The product line includes various configurations based on resolution, interconnection, and output options, with customizations available.

Precision Position Sensors ABSOLUTE POSITION ROTARY ELECTRIC ENCODER™ HARSH ENVIRONMENT The DF-60 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) • Hollow, floating shaft • 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 • Digital interfaces 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 of Electric Encoder™ is a digital serial with absolute position single turn. The combination of precision, low profile, low weight and high reliability have made Netzer Precision encoders particularly suitable to a wide variety of industrial automation applications.
