High speed fiber optic sensors are ideal for sensing gear or sprocket teeth or other targets in applicatioposition control. Selection of the fiber optic sensing tip should involve matching the effective beam of the fiber to the profthe time that the part is sensed and/or the time between adjacent parts. Combining the best selection of fiber tip geometry wia highly repeatable position sensing system.

Timing range is a true overspeed or underspeed sensing logic module that monitors signals fromtime with the reference set by the "HOLD" potentiometer. A jumper allows the mode to be(jumper removed). In the overspeedmode, the output will drop if the preset rate is exceeded. In the underspeed mode, the outputremains energized until the input rate drops below the preset.
