The Omron H7CC-R11 Counter is a precise tachometer for speed and frequency monitoring, equipped with SPDT contact output and high-speed 10 kHz counting capability. Its 6-digit LCD ensures excellent visibility, while UP/DOWN input modes provide flexible integration with various sensors. The device features strong environmental durability with −10 to 55°C operation and IP66 panel protection when paired with waterproof packing. Designed for dependable industrial use, it includes non-volatile memory for long-term data retention. Manufactured by Omron and supplied under Omron Counter offerings, it is part of the Omron H7CC Series.
