Type 634/635 is an electromechanical mini-totalizing counter with a 6 or 7-digit optical display, with standard pattern connector arrangement. The small dimensions and low power consumption make this the ideal device for front panel installation or PCB use. Types 1 and 3 can be machine-soldered and can, if necessary, be washed with no problems. The 634 variant is characterised by its excellent protection against magnetic disturbance, while model 635 is particularly impact-resistant.

Type 464-468 is available as various variants with 4, 6, or 8-digit display. The device is available without a reset, or with a manual or electric reset option. The electro-mechanical totalizing counter stands out because of its user-friendly design. It is a plug-and-play device and can easily be combined with other counters in the modular 400 series.

A key feature of Type 853 is its convenient surface mounting, which guarantees easy mounting of this electromechanical totalizing counter. Further important characteristics are the 6-digit display and a reset button.
