Product catalog summary
Overview: The DS-40 is a rotary electric encoder designed for harsh environments, part of the DS series by Netzer Precision. It features a low profile, hollow floating shaft, and no contact elements, ensuring high precision and reliability.
Mechanical Specifications: The encoder allows for a mounting eccentricity and axial tolerance of ±0.1 mm, with a rotor inertia of 70.93 gr·mm² and a total weight of 20 grams. Its dimensions are 40 mm outer diameter, 10 mm inner diameter, and 10 mm height, made from Ultem™ polymer and TRVX-50.
Electrical Specifications: Operates at a 5V supply voltage with a current consumption of 90 mA. It uses a #30 shielded cable with a maximum length of 5,000 mm.
Environmental Specifications: The encoder is compliant with EMC standards IEC 6100-6-2 and IEC 6100-6-4, operates in temperatures 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 6ms and vibration endurance of 20g from 10 to 2000 Hz, with an IP40 protection rating.
General Performance: Offers an angular resolution of 17-19 bits, with a maximum static error of ±0.020° and extended accuracy static error of ±0.010°. It supports a maximum operational speed of 4,000 rpm and measures single-turn absolute position with adjustable rotation direction.
Interface and Protocols: The encoder supports SSi and BiSS-C interfaces, using a unidirectional serial synchronous protocol for data transmission. The BiSS-C interface is based on RS-422 standards, with a clock frequency of 0.1 to 5.0 MHz and a position update rate of 35 kHz, optionally up to 375 kHz.
Cable Information: The encoder uses a 30 AWG twisted pair cable with a braided shield and a silicon rubber jacket, rated for temperatures from -60 to +150°C.
Recommendations: Avoid using Loctite or cyanoacrylate glues; instead, use 3M Scotch-Weld™ Epoxy Adhesive EC-2216 B/A for mounting. The encoder is suitable for a variety of industrial automation applications due to its precision, low profile, and high reliability.

Absolute Position Rotary Electric Encoder - DS-40 Data Sheet-1

ABSOLUTE POSITION ROTARY ELECTRIC ENCODER HARSH ENVIRONMENT The DS-40 is a member of the DS series of Electric Encoders™ a product line based on Netzer Precision Position Sensor proprietary technology. EE products are characterized by features that enable unparalleled performance: 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. • Hollow, floating shaft • No bearings or other contact elements • High resolution and unparalleled precision • High tolerance to temperature extremes, shock, EMI, RFI and magnetic fields 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. • Very low weight • Holistic signal generation • Digital interfaces for absolute position Angular resolution Supply voltage Maximum tested static error Current consumption Extended accuracy static error Maximum operational speed Cable length Single turn absolute position Rotation direction Adjustable CW/CCW Operating temperature Storage temperature Relative humidity Shock endurance Vibration endurance * Default same direction from bottom side of the encoder Mechanical Allowable mounting eccentricity Allowable axial mounting tolerance ±0.1 mm Rotor inertia Total weight Outer Ø /Inner Ø/ Height
