Product Description:
In commercial and industrial environments, the robust, panel-mounted Danaher 744386-211 electromechanical counter delivers consistent, long-lasting performance.
Every digit can store six digits with a maximum value of 999,999, making this unit great at counting machine cycles, production numbers, or instances of events that need visual counting and a long lifespan. Its typical high-definition white-on-black display is 0.188 inches in height by 0.16 inches in width (4.8 mm by 4.0 mm), making it viewable even under less ideal lighting conditions. It has a maximum count frequency of 600 counts per minute and a minimum on/ off pulse time requirement of 50 milliseconds to detect proper tracking. It has a maximum allowable 5-minute on time at 50% duty cycle, and it can withstand medium-speed automation or machines. The unit itself is powered by the standard 115 VAC power input. It offers a nominal power draw of 6 Watts, making energy efficiency easy to achieve during long-duty cycles.
The count is disabled manually, by use of a rotary thumbwheel, which is simple and tactile, and suitable where the device may often be required to clear the count at a glance, without the use of any tool, or power cycling. It is mounted by ordinary panel installation, and the lead wires are #22 AWG with an extension of 12 inches (305 mm) to allow flexible wiring. The casing and frame are made of zamak, a kind of zinc alloy that is still in use primarily because of its strength and resistance to mechanical stress and corrosion. The 744386-211 weighs 1 lb 2 oz (0.5 kg) and provides a rugged construction with simple readability and ease of operation, which is good in process control, mechanical counting, or repetitive-cycle applications in manufacturing and automation environments.
