Mechanical Rotation
Totalizing counters are used to sum the total number of cycles or inputs to a device. These counters have no “outputs”.
Totalizers can be Mechanical, Electromechanical or Electronic.
Totalizers are typically used to total cycle count, piece count, and linear length or to indicate position. Displays for
Mechanical & Electromechanical Totalizers are molded gure wheels usually displaying 0-9 digits on a contrasting
background and have a count capacity of 3-8 gures.
Mechanical Totalizers
The input for Mechanical Totalizers can be Rotary, Stroke or Rotary Ratchet. Mechanical Totalizers require no operating
power or sensor and are easy to install. For hand operated applications you need to consider our Model 46 with thumb
lever option.
Z
Basic operation of a mechanical stroke counter
The illustration (right) shows the lever in the rest position with a total shaft
rotation of X+Y+Z. Although these angles may dier from model to model,
the total shaft rotation contains a pre-travel (X), a count stroke (Y), and
an over-travel (Z). The lever must start in the pre-travel area and continue
through to the over-travel area to register a count. It is recommended that
the spring furnished with the counter be used to simplify adjustment of
count stroke to drive mechanism.
