Tiny fully-featured contactless rotary sensor supports 50 million cycles
Based on a patented Hall effect technology this new sensor enables for the first time true non-contacting through-hole shaft sensing using standard SMD features. 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 MTS-360 from Piher combines a through-shaft design with 360° absolute position feedback in an ultra miniature size. The result is the smallest fully featured rotary sensor on the market with a reliability up to 50 million cycles. With its tiny size of only 6x17x18 mm (HxWxL) the sensor can be mounted directly on the circuit board without the packaging issues that typically accompany such devices. The exceptionally low profile fits easily in places that were previously too small for pre-packaged rotary sensors.
The contacless sensor relies on the Hall effect to enable true non-contacting through-hole shaft sensing using standard SMD features. The standard model features a 4 mm double D-flat shaft and an 8-pad SMD footprint that is compatible in most reflow soldering systems. The device offers electrical angles up to 360° with no dead band and linearity as low as +/- 0.5%. Rated for use at -40° to +150°C, the sensor can be programmed with full scale output with angles shorter than 360 degrees. Output is selectable between analog, PWM or SPI. A redundant version with a dual core sensor in the same package is also available.
