Super-flat non-contacting rotary sensor
When it comes to position and angular measurements, today's manufacturers often choose magnetic technologies. Hall Effect-based sensors, for instance, yield absolute measurements which are reliable even under tough environmental conditions. Their relatively low cost in comparison with other measurement technologies makes them suitable for countless applications in machine engineering and plant design as well as for mobile applications. In light of recent developments, this trend is expected to continue.
Novotechnik has responded to the increasing demand for simple, flat, and affordable rotary sensors with the development of its new RFD component series. These non-contacting Hall Effect-based components are mechanically and electrically compatible with their predecessor, the RFA, yet distinctly more economically priced - in the absence of technological sacrifices. These highly reliable and powerful sensors are suitable for measurement angles of up to 360 degrees. They offer a 12-bit resolution and an independent linearity of +/- 0.5 per cent, and they are available in single, partially, or completely redundant designs.
The flat sensor housing measures only 7mm in height. It is made of a sturdy thermoplastic material, and its two injection-moulded screw mounts are reinforced with brass bushings (distances between bores: 31mm). The included matching position transducer also features a small footprint, with a diameter of 22.2mm and a height of 5.6mm. It, too, is constructed of a thermoplastic material with injection-moulded brass bushings. Lateral installation offsets of +/- 1.5mm will not compromise measurement integrity. In addition, the sensor side is clearly labelled, thus simplifying installation. These sturdy sensors may be used in the fields of industrial and automotive technology, especially in light of their technological and economic advantages coupled with their attractive design.
