PREDETERMINING COUNTERS
Predetermining counters (or preset counters) are essentially totalizers
that can switch an external circuit when its counted total matches a
user-entered preset limit. They can be used in manufacturing and
process applications to control batch lot size, cutting material to length,
punching or drilling, and many other count, position, or length related
operations.
When selecting a predetermining counter, it is important to consider
which technology is most appropriate for the application.
Mechanical predetermining counters are very easy to install and
operate, and require no operating power or input sensors. They are
ideal for relatively slow batching and measuring operations, such as
stopping a machine when a preset quantity of parts, cycles, or length
has been produced. Flexible enough to fit almost any application –
many mounting styles, count capacities, drive ratios, shaft rotations and
reset features are available.
Counting is accomplished through direct coupling to a rotating or
reciprocating machine element, such as a shaft, measuring wheel,
lever, or cam. When its preset count value is reached, a switch contact
output is provided for controlling an external circuit. A manual reset is
usually required before the process can be repeated.
The mounting location for a mechanical counter is greatly influenced by
its linkage or coupling requirements, therefore display visibility and
convenient access to preset and reset features should be contemplated
when planning an application.
Electric predetermining counters are ideal for relatively slow batching
operations. Since counting is not dependent on mechanical attachment
to machine elements, they can be installed at locations that are remote
from the origin of the count signal. The input signal is a voltage source,
impulsed through switch or relay contacts, or a proximity switch or
photoelectric sensor. We offer a variety of packaging and mounting
styles, reset features, and have standard models covering all popular
AC and DC voltage ratings.

SPECIFYING A PREDETERMINING COUNTER
Basic considerations when selecting a predetermining counter for your
application are:
Additional selection criteria for predetermining counters include:
Technology – Mechanical, Electrical, Electronic (See our electronic
predetermining counters in Section 2).
Input – What is to be counted and from where will the counter’s input
be obtained?
Count Speed – Speed ratings vary. Check Specifications.
Number of Digits – Based on Maximum Count Value
Type and Size of Display – Should accommodate operating
environment’s viewing and lighting conditions
Packaging – Mounting requirements and Enclosure Size
Environmental – Temperature Specification
Output Device: Most predetermining counters include internal
contacts that can switch a wide voltage range of AC or DC circuits
that draw moderate power. The relay is capable of directly controlling
solenoids, valves, shears, lights, buzzers, etc.
Output Action: Electric and mechanical preset counters usually
provide output contacts that are maintained on (latched), until the
counter is manually reset.
