The Omron K3HB-PPB 100-240VAC is a panel-mount time counter from the K3HB-P series, running on 100-240VAC supply. It counts events up to 50 kHz — that's fast enough for high-speed packaging lines or machine cycle monitoring, where you need to tally parts or shaft rotations at speed. The 50 kHz figure is the maximum count rate; actual reliable counting depends on sensor pulse width and duty cycle, but for most production machinery it's not the bottleneck. The front panel carries an IP66 rating — dust-tight and protected against water jets. That means it survives washdown in food processing or wet machining environments without a secondary cover. The housing seals at the panel gasket, so the electronics stay dry even when you hose down the enclosure face. Reset is external — you wire a dry-contact pushbutton or PLC output to the reset terminals. No menu-diving to clear the count; it's a hardwired signal, which is what you want when the line-down procedure calls for a remote reset from the HMI or a floor-level button station.
Mounts into a rectangular cutout 92.00 mm x 45.00 mm — standard 1/8 DIN panel hole. Screw terminals on the back for supply, input, and reset wiring. No special connector tooling needed; strip, terminate, torque. The dual-color LCD backlight (5+5 character rows) shows the count and a second parameter like preset or total simultaneously, which helps during setup without toggling screens. If the panel sits near a furnace or in direct sun, watch the internal rise — the spec is ambient at the unit, not inside a sealed black box.
