The Omron K3HB-CNB 100-240VAC is a panel-mount totalizer from the K3HB series, accepting no-voltage and voltage input signals at count rates up to 50 kHz. It counts up, down, individual, or quadrature — so it handles everything from simple part-increment to encoder-based position tracking on a conveyor or rotary table. The front panel carries an LCD with dual-color backlighting and two rows of five characters each (0.560" and 0.192" character heights), giving you a main count and a secondary display for batch or preset value. Reset is via the front panel or programmable logic, which matters when you need a remote reset from a PLC without reaching the enclosure. Supply is 100-240 VAC, so it drops straight into a standard control panel without needing a separate 24 VDC power supply. The IP66-rated front bezel means it survives washdown splashes and dust — fine for food, beverage, or packaging lines where the panel gets hosed down.
Mounting and panel cutout
Mounts into a rectangular panel cutout of 92.00 mm x 45.00 mm and secures with screw terminals on the rear. The termination style is screw terminal — no special crimp tool needed, just a standard slotted driver.
