Rotary Sensor Breaks Size And Functionality Barriers

Reported as a breakthrough, the non-contacting MTS 360 SMD rotary position sensor combines a through-shaft design with 360º absolute position feedback in an ultra miniature package. The result is the smallest, full-featured rotary sensor on the market with reliability up to 25-million cycles. The component measures 6 mm x 17 mm x 18 mm and employs 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. Other features include electrical angles up to 360° with no dead band and linearity as low as ±0.5%, operating temperature range from -40ºC to +150ºC, operating speeds up to 300 rpm, full scale output programmable for angles shorter than 360, and the output is selectable between analog, PWM 12-bits, or SPI at 14 bits. A second output channel provides a programmable switch signal and a redundant version is available with a dual core sensor in the same package. Price is $8 each/250,000.
