Product Description:

The 0727245-001 is a mechanical event counter manufactured by Danaher as part of its Timers and Controllers series. Designed for integration into industrial machinery, the unit tallies one count for every qualified rotary input so operators can track cycles, strokes, or completed parts without electrical power. The device fits applications where a simple, self-contained totalizer improves preventive maintenance accuracy and overall process monitoring. Its small footprint and manual reset capability allow it to mount close to the motion source, reducing wiring and simplifying installation in presses, packaging stations, or indexing tables.

The counter body is molded from glass-filled nylon, providing electrical insulation and impact resistance while keeping weight low. A ratchet drive mechanism advances the display, registering exactly one count per actuation when the shaft turns through a minimum arc of 40°. The drive can sustain harmonic input speeds up to 1000 cpm, so it keeps pace with high-cycle machines without miscounts. The gear train needs only 30 ms of dwell after impact before the next advance. The five-wheel register presents white numerals on a black background for high contrast, and the display area remains legible in narrow mounting spaces.

Installation is straightforward because the unit attaches to a base mount, and its shaft, machined from stainless steel, accepts cams or linkages that stay within the 45° travel limit set by the housing. The counter weighs only 2.4 oz, so it adds negligible mass to light actuator arms. When the total needs to be cleared, the front-panel reset knob can be turned without tools, returning all five figures to zero. Character height is 0.187 in, while character width is 0.099 in, providing clear digits despite the compact outline. The high-contrast digits and compact register size suit confined enclosures where quick visual confirmation is required.
