Contactless rotary position sensor

21 March 2012 Test & Measurement

The MTS360 from PIHER is a contactless sensor combining a through-shaft design with 360° absolute position feedback in an ultra miniature size. The result is a compact, fully featured rotary sensor with reliability up to 50 million cycles.

With its tiny size of 6 x 17 x 18 mm (HxWxL), engineers can now integrate a fully featured rotary sensor directly on a PCB without the packaging issues that typically accompany encoders or other absolute position devices. The low profile fits easily in places that were previously too small for pre-packaged rotary sensors.

The MTS360 relies on patented Hall-effect technology to enable true non-contacting through-hole shaft sensing using standard SMD features. The offset through-hole accommodates a vacuum pick-up tool, allowing use in automated SMD assembly systems. The standard model features a 4 mm double D-flat shaft and an 8-pad SMD footprint that is compatible with most reflow soldering systems.

The new device offers electrical angles up to 360° with no dead band and linearity as low as ±0,5%. Rated for use at -40°C to +150°C, the sensor can be programmed for full-scale output with angles shorter than 360°. Output is selectable between analog, PWM up to 12 bits or SPI up to 14 bits, and includes a second output channel to provide a programmable switch signal. A redundant version with a dual-core sensor in the same package is also available.

This rotary position sensor is ideal in optical imaging stabilisation and precision biomedical devices, optical zoom devices, consumer electronics, instrumentation, HVAC systems, automotive control systems, marine controls, forklift trucks, farm equipment, cranes, low-speed motor feedback, valve position sensors and robotic and automation feedback systems.
