HIGH-SPEED SCANNER BLOCK

Fiber optics are often used to sense small parts. Small parts or narrow profiles which move at a high rate of speed can require sensors with fast response times for

reliable detection. High speed fiber optic sensors are ideal for sensing gear or sprocket teeth or other targets in applications involving counters or shift registers for

position control. Selection of the fiber optic sensing tip should involve matching the effective beam of the fiber to the profile of the part to be sensed to maximize

the time that the part is sensed and/or the time between adjacent parts. Combining the best selection of fiber tip geometry with a high speed sensor will result in

a highly repeatable position sensing system. The model BT13S fiber optic assembly used with a model L9 or L16F lens and a high speed scanner block is an excellent

system for retroreflective code reading or for almost any short range retroreflective sensing application. Response time of a MULTI-BEAM sensor is also a function

of the power block. For this reason, only power blocks which switch dc (e.g. PBT, PBP, PBO, PBAT, etc) should be used if the fast response time of the scanner

block is to be utilized.
