Are you sure it is the sensor itself?  We have found that the axis is often
"off" a bit from canonical LEGO spacing, and if built into a structure,
binds quite a bit.  But if you assemble it so that the body (blue) of the
sensor can "float" with respect to the axis, then it works fine.

The test would be to simply turn it with an axle by hand.  If it doesn't
feel free in that case, then it is a faulty or damaged part.  I assume you
have done this, but thought I would mention this common problem for the
lurkers.

Hi, All.

I'm having a problem with a rotation sensor and I was wondering if • somebody
already solved that.
I have 2 rotation sensors. One of them works fine. The other one works • well
as a sensor but the rotating axle has considerable friction. Since I • usually
gear it down for precision, the torque generated by this friction is
"amplified" and is causing some trouble. For example, if I use a clutch • gear
it usually slips.

Is there anyway I can solve that without disassembling the rotating • sensor?
I thought about lubrification but I'm afraid to damage it. Could this
friction reduce with time due to usage?

Yes, Gregory, I'm sure. When I mention the sensor I mean the whole thing, not only the eletronics part. I tested both sensors and I tried to tilt the axle to test the behaviour you mentioned. After playing with it a little, it seens the casing don't (...) (22 years ago, 26-Jun-02, to lugnet.robotics)
