8-digit backlit LCD total counter. Features IP66/NEMA 4X washdown protection, internal battery, and 4.5-30 VDC input for reliable industrial pulse counting.
The Omron H7EC-NV-H is a highly compact, self-powered 8-digit total counter designed for precise industrial tallying and tracking applications. It features a high-visibility, transmissive LCD with an 8.6mm character height and built-in backlighting for readability in poorly lit environments. This 1/32 DIN totalizer accepts a universal PNP/NPN DC voltage input (4.5 to 30 VDC) and supports selectable counting speeds of 30 Hz or 1 kHz. Housed in a durable light gray case with an IP66/NEMA 4X rated front panel, it ensures resilient operation against dust and water washdowns. An internal 3V lithium battery sustains the counting logic independently of the main power system, while an external 24 VDC source powers the backlight display.

Integrating the totalizer at the end of an automated manufacturing conveyor to continuously count finished goods using photoelectric sensors.
Provides a reliable, independent count that does not reset during facility power outages, while the backlit display allows operators to clearly read tally numbers from a distance in low-light factory settings.
Mounted on a CNC or stamping press control panel to tally exact mechanical strokes and trigger preventive maintenance scheduling.
Reliably tracks machine cycles directly from proximity switches without burdening the main PLC. Its robust front panel prevents cutting fluids and industrial debris from damaging the electronics.
Connected as a local readout device tied to a flow meter's pulse output in a water or chemical pumping facility.
Provides immediate, on-site volumetric pulse counting with a high-visibility readout. The heavy-duty enclosure rating withstands routine facility washdowns.
