Product Description:

The 0744386-211 is a panel-mounted electronic counter supplied by Danaher within the Timers and Controllers series. In automated assembly lines or packaging machinery, it records event totals and governs basic on-off cycles, allowing upstream sensors to initiate timed logic without a PLC. The six-digit display and rotary thumbwheel reset make it suitable for local operation where quick visual confirmation of part counts or elapsed process strokes is needed.

The counter is energized from a nominal supply of 115 VAC, and its internal circuitry draws only 6 W, so cabinet thermal rise is minimal. Operation remains stable when the mains supply drifts by up to ±10 V, providing a useful margin in plants with fluctuating power. A maximum counting speed of 600 cpm lets the unit register ten transitions per second without missing pulses. Both the minimum on time and the minimum off time are 50 ms. Input contacts must therefore remain closed or open for at least that long to ensure accurate recognition. Six digits are presented on the faceplate, with each character measuring 0.188 inches high and 0.16 inches wide for clear legibility while conserving panel space.

The timing output can remain active for up to 5 minutes at a 50 percent duty cycle before the circuit must reset, making the device useful for short process dwell periods. The factory-installed leads measure 12 inches (305 mm) and are made from #22 AWG wire, allowing connection to terminal strips without additional splicing. The housing has a depth of 2.530 inches (64.3 mm), so the counter fits shallow enclosures, and panel retention hardware is included. Its net weight is 1 pound 2 ounces, which limits the load placed on thin-gauge cabinet doors while maintaining a sturdy installation. The unit mounts through a standard rectangular panel cutout.
