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.

| 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)

| 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 (...) (22 years ago, 25-Jun-02, to lugnet.robotics)
