If dirt, dust, grease, humidity and other contaminants that commonly impair the performance of optical encoders are an application concern, magnetic rotary position sensors are possible alternative. With a total system cost normally far lower than the cost of an equivalent optical encoder or resolver, ams new version of its 47 series of magnetic rotary […]

Magnetic Absolute Rotary Encoders Achieve Accuracies of up to 0.1°
Targeting tough ambient conditions such as dirt, vibrations, or extreme temperatures, Pepperl+Fuchs designed its ENA58IL and ENA36IL magnetic absolute rotary encoders to deliver high precision and resolution as well as an extremely durable, compact design. To achieve this, the design adds a Wiegand sensor to a two-axis Hall sensor. The Halls sensor measures changes in […]
Absolute Encoders Fit in Cramped Application Spaces
SICK’s AHS/AHM36 absolute encoders are only 36 mm in diameter. The single-turn and multi-turn magnetic encoders have a 270° rotating M12 connector or cable outlet for easier installation in limited spaces. Available products include: face mount flange, servo flange and blind hollow shaft versions each with five different shaft diameters and various adapters. With either […]
Magnetic Position Sensor Provides High Accuracy
With Dynamic Angle Error Compensation (DAEC™), a patent-pending technology developed by ams AG, its new “47 series” position sensors eliminate the measurement error attributable to propagation delay. The 47 series includes the AS5047D, AS5147 and AS5247. Propagation delay (typically 100-200 µs) occurs in traditional magnetic rotary position sensor ICs as they convert raw measurements of […]
Absolute Rotary Encoders for Harsh Environments
When established products evolve to address additional market requirements customers usually benefit. This is certainly the case for sensor users that need an absolute rotary encoder to work in a harsh environment. Building on its ISA and IHA 600 series of absolute rotary encoders, Leine & Linde introduced the IXA 600 stainless steel model that […]
