The Omron H7CC-R Counter functions as a high-precision tachometer offering accurate speed measurement up to 10 kHz, with SPDT contact output support. Its 6-digit LCD delivers clear RPM and frequency indication, while UP/DOWN input flexibility enhances compatibility across sensors. Designed for industrial reliability, it features strong noise immunity, −10 to 55°C operation, and 11-pin socket mounting. Non-volatile memory preserves measurement data even during power loss. Manufactured by Omron and listed under Omron Counter solutions, this tachometer belongs to the Omron H7CC Series.
