Different Types and Applications Of Totalizing Counters

Totalizers are counters that “total” the number of cycles applied to their inputs. The totalizing function does not provide control outputs or preset limits, although some of our multi-function products have the totalizing capability as well as output and control functions. They may be a mechanical counter, electromechanical counter or an electronic counter, all of which may be resettable or non-resettable.

Mechanical Counters

Mechanical totalizing counters typically use printed wheels or drums to display the count value, and are actuated by an external force on a lever or shaft in a reciprocating or rotating action. Mechanical totalizing counters are very robust in their construction and are often found in severe environments which could destroy other types of counters.


A mechanical totalizing counter can be used as a yardage counter for sheet goods, fabric, upholstery, etc. in a factory or commercial setting.

743415-005 Worm Drive is part of the 7234 series and pairs well with 15537-070  Measuring Wheels.

Electromechanical Counters

Electromechanical totalizing counters generally are operated by an electrical pulse from a switch or relay and increment counts as the pulses are applied. Certain models have counting coils designed as “continuous duty” which means that the voltage applied to the counter may be of extended length or continuous without causing damage to the coil. They are typically panel mounted or base mounted and offer a low to mid-range cost solution for numerous applications.


An electromechanical totalizing counter can be used to count cycles in a gaming machine.

779086-006 is part of the 7790/7791 Series. This series of economical miniature totalizers is available in all popular mounts and operating voltages.

Electronic Counters

Electronic totalizing counters are almost always panel mounted, and generally have a good degree of environmental protection making them suitable for wet, damp, or dusty locations. They may be self-powered by an internal battery or externally powered, and are designed to accept a wide range of count inputs like dry contact closures, voltage pulses, TTL level inputs, and quadrature inputs from incremental encoders. Some models offer scalable inputs, meaning that the number of input pulse can be scaled as they come in to result in a readout of more meaningful units of measurement, often referred to as engineering units.


An electronic totalizing counter can be used as a maintenance or usage counter (for revenue) in a copier machine.

Typical Veeder-Root Counter

C342-0462 is one counter in the C342 Totalizing Counter series. This series provides ultra-compact 1/32 DIN totalizers available with LCD or LED display and AC/DC inputs.
Totalizing counters, in all their various types, are an important component in a myriad of applications. So, choose Veeder-Root totalizing counters for a totally reliable, durable, and accurate solution!
