Frequency counter - K3MA-F

Omron K3MA-F frequency/rate meter has a broad input range including contact, voltage pulse, NPN, or PNP input. It has a bright LCD display with 2-color LEDs, red and green. Settings can be made easily using the front-panel keys. The front panel is water- and dust-proof NEMA4X (IP66 equivalent).

Flicker is suppressed by the average processing function. It includes features such as auto-zero time, startup compensation time and scaling. The max/min display can be easily confirmed. When measured from the edge of face plate, it has a short depth of 80 mm.

K3MA-F features 12 VDC, 40 mA external external power supply. Protection against electric shocks is provided by a standard finger protective cover. Under the Component Recognition Program of UL, K3MA-F has been recognized to U.S. and Canadian standards. It also has a CE marking.
