Panel tachometer for speed monitoring
The Omron K3MA-F 24VAC/VDC is a panel-mount tachometer from the K3MA-F series, designed for rate and speed display in industrial control panels. It accepts no-voltage or voltage input signals and counts up to 5 kHz, which covers most encoder and proximity-sensor pulse trains from conveyors, pumps, and spindle drives. Supply is 24VAC/DC, so it drops into existing 24 V control circuits without an extra power module. The 5-digit LCD with dual-color backlight shows rate values clearly even in dim panel lighting.
IP66 front panel — washdown-ready
The front face carries an IP66 rating, meaning it's dust-tight and protected against hose-directed water. That makes it suitable for food-and-bev washdown zones or outdoor cabinets where the panel face sees moisture. The rectangular cutout is 92.00 mm × 45.00 mm — a standard 1/8 DIN footprint — so it retrofits into existing panel punches without adapter plates. Screw-terminal connections on the rear keep field wiring simple; no special crimp tools needed.
