Speed sensor (D) (sizes 23...180)
Version AA2FM...D ("prepared for speed sensor") includes gearing
on the rotary group and in addition the port M in which a speed
)
sensor is screwed in.
A speed-proportional signal is produced by means of the rotating,
)
splined rotary group which can be picked up by a suitable sensor
and fed back for evaluation.
)
The speed sensor can be screwed into port M (thread metric
M18x1,5).
