Home Omron Counters H7CC Series H7CC-R11D Omron H7CC-R11D Counter The Omron H7CC-R11D Counter is a precision tachometer engineered for high-speed rotational and frequency measurement in industrial systems. It supports dual input channels with count-and-hold functionality, a fast 10 kHz maximum counting speed, and SPDT contact outputs for reliable control. The clear 6-digit LCD display enhances visibility, while IP66 panel protection ensures durability in demanding environments. With flexible NPN/PNP input compatibility and stable 24 VAC/12β48 VDC operation, it fits a wide range of machine monitoring requirements. Manufactured by Omron and listed under Omron Counter solutions, it belongs to the Omron H7CC Series .
