CX901A6

The Danaher CX901A6 timer is a robust member of the Timers and Controllers series, engineered for precise reset timing in industrial automation applications. This electro-mechanical unit provides 6 display figures on electro-mechanical wheels, driven at a count speed of 1000 cpm to ensure accurate timing resolution. It supports both 115 VAC and 230 VAC operating voltages with an allowable variation of ±10 volts, and delivers a 240 VAC output capable of driving loads up to 10 A. The front panel integrates a recessed inset LCD with optional one- or two-line alphanumeric display, coupled with a 12-key tactile keypad for direct parameter entry. Designed for panel mounting via snap-fit latches or base mounting with lock-and-key reset options, the CX901A6 balances durability with user-friendly operability.

Technical specifications for the CX901A6 are detailed and comprehensive. The timer features a minimum on/off time of 30 ms, ensuring rapid switching cycles, and consumes only 6 watts of power during normal operation. Its 0.188 in H × 0.156 in W figure size provides clear readability, while the bobbin is molded from nylon for electrical isolation. The wheels and pinions utilize a high-grade plastic material to reduce wear, and the glass-filled zamak frame and covers offer robust mechanical protection. Connection is made via #22 AWG leads, each 7.5 in (190 mm) in length, terminating in a 14-pin rotary socket for secure field wiring.

Operational features emphasize reliability and ease of maintenance. The manual rotary or lock-and-key reset mechanism ensures positive reset engagement, eliminating false triggers in high-vibration environments. Net weight varies by configuration—397 g for base mount, 567 g for panel mount, and 680 g for lock-and-key reset—allowing system designers to account for panel loading and support structure requirements. Phenolic resin plastic forms the rear housing, delivering excellent insulation and environmental resistance. The inset keypad design protects against accidental activation, and the recessed display minimizes the risk of screen damage in harsh industrial settings.

System integration is streamlined through standard industrial mounting and electrical interfaces. The CX901A6 can be installed alongside PLC modules or process control panels, requiring no external programming tools thanks to on-board keypad configuration. With its combination of precise timing capabilities, multiple reset options, and robust construction, the CX901A6 is ideally suited for applications such as conveyor control, batch processing timers, safety interlock resets, and automated machinery cycle control in manufacturing and process industries.
