Vishay Intertechnology has introduced a new miniature position sensor with a small 12.7 mm outer diameter that delivers higher accuracy and resolution than competing devices in the same size — offering increased reliability and durability for the harsh operating environments of military and industrial applications.
The Vishay MCB RAME012 rotational absolute magnetic encoder uses advanced contactless technology to achieve > 11-bit accuracy and 14-bit resolution, maintaining robustness against external magnetic fields, airborne pollution, vibration, mechanical shock, and changes in temperature.
The device features a useful electrical angle of 360° and works over a temperature range of -40° to +105° C.
The body design of the RAME012 — as well as its on-axis design, slim diameter, and light weight (< 11 g) — make it ideal for applications where little space is available, but an angular position needs to be detected with high accuracy. The device is available in a single-turn variant featuring an SSI output signal, with other mechanical and electrical interfaces also available on request.
With its SSI output and excellent performance / size ratio, the position sensor released today offers a perfect replacement for potentiometers in missile guidance systems, gimbals for optical balls and missile seekers, positioning systems for small industrial actuators (servo drives), and the multi-dimensional mechanical measurement of surfaces using 3D probes.
The key advantages of the RAME012 are:
- High accuracy > 11 bits
- Small outer diameter of 12.7 mm
- SSI output
- Plug-and-play operation, eliminating the need for calibration
- Wide operating temperature range from -40° to +105° C
- Stainless steel body
This technology architecture provides the best performance with safety guarantees. Samples and production quantities of the RAME012 are available now, with a lead time of 20 weeks for larger orders.
