FEATURES
TT-100™ Dynalco Tach Tape is a strip of
flexible magnetic polymer backed with a
pressure sensitive adhesive. This adhesive
adheres to a wide variety of surfaces,
including most plastics and metals.
Because of its unique magnetization and
arrangement of slots, a series of alternate
magnetic poles is generated along the length
of the tape. A Dynalco magnetic pickup
becomes activated when placed perpendicular to the moving tape surface.
Figure 1 (next page) demonstrates that the
Tach Tape performance is better than an
8-pitch gear when the air gap is larger than
0.050 inch (0.127 cm). This is especially
welcome in cases where a small air gap is
difficult to maintain, or space is too restricted
to install split gears.
