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.
