That speed handles high-speed packaging, bottling, or part-increment lines where a standard PLC counter might alias. The 24 VAC/DC supply means you can pull power from either an AC control transformer or a DC bus without swapping the unit — a single part number covers both panel architectures. The counting modes include Up, Down, Individual, and Quadrature, so it works with simple proximity switches (NPN/PNP, no-voltage or voltage inputs) or quadrature encoders for bidirectional position tracking. The front-panel programmable reset lets an operator zero the count without opening the enclosure — useful for batch-changeover lines where the panel stays sealed. ## IP66 front panel — washdown-safe for food, beverage, and wet environments The front face carries an IP66 rating, meaning it's dust-tight and protected against powerful water jets. That makes it suitable for food-and-beverage washdown zones or outdoor cabinets where a standard panel-mount display would fog or fail. The rear of the unit is not rated the same — the IP66 seal is at the bezel gasket; ensure the panel cutout is properly gasketed on the back side to maintain the enclosure integrity. Mounts into a standard 92 mm × 45 mm rectangular cutout (1/8 DIN footprint) and secures with screw terminals — no special tooling needed. The LCD shows two rows of five characters each: a 14.20 mm main row for the count value and a 4.90 mm secondary row for batch or preset data. Backlight is included for readability in low-light cabinets. ## Active lifecycle — no obsolescence concern, standard sourcing channel The K3HB-CNB 24VAC/VDC carries an active product status.","metaTitle":"Omron K3HB-CNB 24VAC/VDC Totalizer, 50 kHz, IP66, 24 VAC/DC","metaDescription":"Omron K3HB-CNB 24VAC/VDC totalizer, 50 kHz count rate, front-panel programmable reset, IP66 front, 24 VAC/DC supply.
