We have produced an optical sensor on a clamping arm that will allow you to use the optical sensor on wall- hanging clocks or on house calls much more easily. The sensor is based on a bar clamp with rubber jaws. You can safely clamp this to the side of the clock. An articulated arm made of anodized aluminum is fastened to the clamp with an optical sensor at the other end. You can position the arm to locate the optical sensor under the bob of the clock you're working on.
The following images show the Clamping Optical Sensor on a variety of clocks.

The Clamping Optical Sensor can be ordered on the MicroSet Order Form. You also order it without the optical sensor (use your own).
