Part no.: Netzer DS-40
• 40mm diameter
• SSI, BiSS-C
• Up to 20 bit resolution
• High tolerance to EMI, RFI and magnetic fields
The DS-40 is a member of the DS series of Electric Encoders a product line based on Netzer Precision Motion Sensor proprietary technology. Lightweight, compact and high performance (up to 19 bit resolution) these encoders provide unparalleled performance. 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.

Introduction to Intrinsically Safe Sensors
Intrinsically safe (IS) sensors are unable to produce a spark strong enough to cause ignition. Learn how this is accomplished and design considerations when using IS sensors.
Intrinsically Safe Absolute Rotary Encoders
In the most hazardous environments, where an explosive atmosphere consisting of flammable gas or vapor is regularly present and a sensor fault cannot be risked, Intrinsically Safe (IS) sensors may be the best sensing option. Generally, these sensors are paired with a barrier which limits the amount of electrical and thermal energy that can enter the Hazardous Area to an amount that is so small that even in the situation of a sensor fault, there is not enough energy to cause an ignition.
Accuracy, Resolution and Repeatability
There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.
Tiny Tech, Big Impact: Rotary Encoders Are a Critical Link the Agrobot Revolution
A recent GlobalData report highlights the impressive growth of the robotics industry in agriculture (reaching $218 billion by 2030), a key component behind this revolution often goes unnoticed: the rotary encoder. These unsung heroes convert rotational motion into precise electrical signals, playing a vital role in ensuring the smooth, accurate movements of agricultural robots.
