The H7CX-A114S-N is a versatile multifunction counter and tachometer from Omron's H7CX series. Designed for high-reliability industrial monitoring and control, this unit serves as both a precise counter for event totalization and a tachometer for speed or flow rate measurement. Its compact 48 x 48 mm panel-mount design (approx. 4.8 x 8.41 x 4.8 cm) makes it an ideal fit for control panels where space is at a premium.
This specific model is the "standard" type, utilizing an 11-pin socket for quick, secure external connections. It features a 4-digit display, single-stage output setting, and a reliable transistor output for high-speed switching applications. It operates on a wide input voltage range of 100 to 240 VAC, ensuring compatibility with standard industrial power environments.

Installation Guidelines
Mounting: Use the provided bracket to secure the unit in a standard 48x48mm panel cutout. Ensure the 11-pin socket is firmly seated to prevent vibration-induced signal disconnection.
Socket Wiring: Use a high-quality 11-pin round socket (such as the Omron P2CF-11) for stable electrical contact. Ensure all terminal connections are tightened correctly.
Input Signal: Configure the input mode (NPN or PNP) based on your sensor output type. Shielded cables are recommended for input signals to prevent electromagnetic interference (EMI) from affecting count accuracy.
Configuration: Use the front-panel keys to set the counter/tachometer mode and scale factors. Refer to the user manual to match the scaling to your specific mechanical requirements.
