The options when specifying sensors for long-range object detection or positioning usually boil down to two alternatives: optical sensors using either infrared or visible-red light and ultrasonic. Optical sensing is often the first choice
A variable-pitch wind-turbine blade adjusts its angle with changing windspeed for higher efficiencies over a greater range of wind speeds and helps prevent turbine blade runaways and other dangerous conditions.
Robust roller-pinion systems replace traditional rack-and-pinions along with other technologies for applications needing accuracy, long service life, and minimal maintenance.
