It accepts both no-voltage and voltage input signals, counts up at a 50kHz rate, and resets externally via a dedicated signal. The dual-color LCD with backlight shows two rows of five characters each — the main display at 14.2mm height and a smaller sub-display at 4.9mm for secondary data like preset values or batch totals. The 50kHz count rate means this counter can catch fast events like a sensor on a high-speed packaging line or a rotary encoder on a servo-driven conveyor — it won't miss pulses at typical production speeds. The external reset is a hard-wired input, so you can tie it to a PLC output or a pushbutton for remote clearing without opening the panel. The IP66 rating means the front face is dust-tight and protected against hose-directed water — let me show you why that matters: you can mount this on a panel that gets washed down in food, beverage, or pharmaceutical lines without worrying about moisture getting into the display or the screw terminals. Mounts in a rectangular panel cutout of 92.00mm x 45.00mm — that's a standard DIN-size opening for 1/8 DIN instruments, so it fits existing punch patterns without rework. The screw terminals on the back accept solid or stranded wire; strip length and torque follow standard panel practice.","metaTitle":"Omron K3HB-PNB 24VAC/VDC Time Counter, 50kHz, IP66","metaDescription":"Active production Omron K3HB-PNB 24VAC/VDC time counter. 50kHz count rate, external reset, IP66 panel mount, 24VAC/DC supply.

The closest sibling is the K3HB-PNB with a different supply voltage — same panel cutout, same 50kHz count rate, same IP66 front. The deciding factor for the 24VAC/VDC version is whether your control voltage is already 24V; if you have 100-240VAC available, the AC-powered sibling avoids a separate power supply. No pin-compatible drop-in exists without checking the terminal assignment for the supply pins."},{"question":"What compliance documentation is available for this counter?","answer":"As an active Omron industrial product, the K3HB-PNB 24VAC/VDC carries CE marking for the European market and UL/CSA listing for North America. RoHS and REACH compliance declarations are standard with the series. The specific certification numbers are printed on the nameplate; request the declaration of conformity from your distributor if your quality system requires it on file."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/K3HB-PNB-24VAC-VDC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/K3HB-PNB-24VAC-VDC when reusing this data.
