The Omron K3HB-CPB 100-240VAC is a panel-mount totalizer from the K3HB series, counting events at rates up to 50 kHz from no-voltage or voltage inputs. The 100~240 VAC supply powers the dual-color LCD backlit display, showing two rows of five characters each — the main count and a secondary value like batch total or preset. The front panel carries an IP66 rating, meaning the display and buttons hold up against hose-directed water and dust ingress — suited for washdown environments on packaging or bottling lines. The screw-terminal rear connection keeps field wiring straightforward for panel builders.
The 50 kHz count rate covers most high-speed sensor applications — proximity switches, encoders, or photoelectric sensors on fast-moving conveyor or rotary indexing stations. The quadrature counting mode handles direction-sensing encoder inputs, while up/down and individual modes cover simple event accumulation or bidirectional flow. Reset is programmable from the front panel, so the operator can zero the count without opening the enclosure. The panel cutout is 92.00 mm x 45.00 mm — a standard 1/8 DIN footprint — which drops into existing panel holes without adapter plates.
