MTS 360 SMD Rotary Position SensorThe non-contacting MTS 360 SMD Rotary Position Sensor combines a through-shaft design with 360º absolute position feedback in an ultra miniature size. The result is the smallest fully featured rotary sensor on the market with reliability up to 50 million cycles. With its tiny size of only 6mm x 17mm x 18mm (HxWxL), engineers can now integrate a fully featured rotary sensor directly on their PCB without the packaging issues that typically accompany encoders or other absolute position devices. The exceptionally low profile fits easily in places that were previously too small for pre-packaged rotary sensors. The MTS 360 relies on the company’s patented Hall effect technology to enable for the first time true non-contacting through-hole shaft sensing using standard SMD features. The offset through-hole accommodates the vacuum pick up tool, allowing use in automated SMD assembly systems. The standard model features a 4mm double D-flat shaft and an (8) pad SMD footprint that is compatible in 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 -40ºC to +150ºC, the sensor can operate up to 300 RPM and can be programmed with full scale output with angles shorter than 360 degrees. Output is selectable between Analog, PWM 12 bits or Serial Protocol (SPI) at 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.
