Rotary Pulse Indicator
K3HB-R
CSM_K3HB-R_DS_E_15_2
Digital Rotary Pulse Meter Capable of 50 kHz Measurements
• Visual confirmation of judgement results through display colors that switch
between red and green. *1
• Measures High-speed Pulses at 50 kHz.
Provides high-speed pulse measurements up to 50 kHz of rotary encoder or ON/OFF pulse
signals and can perform rotating measurement of high-speed rotating objects.
Note: No-voltage contacts of up to 30 Hz are supported.
• Six Measurement Operations Including Rotation (rpm)/Circumferential
Speed, Ratio, and Cumulative
One Rotary Pulse Meter has 6 rotary pulse measurement functions to support a variety
of pulse measurement applications. Select the best function for your application from the
following: Rotation (rpm)/circumferential speed/instantaneous flowrate (value
proportional to frequency), absolute ratio, error ratio, error, flow rate ratio, and passing
speed (value inversely proportional to frequency).
• DeviceNet models added to the series. *2
*1 Visual confirmation of judgement results is not supported on models that do not have an output
or models that do not support DeviceNet.
You can change the display color by setting it, but you cannot switch it based on the judgement results.
*2 DeviceNet models have a depth of 97 mm.
For the most recent information on models that have been
certified for safety standards, refer to your OMRON website.

Meters.

The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is
to count the ON/OFF time (T) for input sensor or other device inputs using the internal system
clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and
displayed as the rotation (rpm) speed.

K3HB-R
■ What Is Prescaling?
■ What Is the Auto-zero Function?
To make calculations using the input pulse to display rotation (rpm)
or circumferential speed, the number of pulses per rotation or the
length of the circumference must be multiplied by a certain
coefficient. This coefficient is called the prescale value.
K3HB-R
(Set this function before using the Digital Indicator.)
If a function f1 to f6 is set, the frequency can be force-set to zero if
there is no input pulse for a set period. This period is called the autozero time. Set the auto-zero time to slightly longer than the longest
input pulse interval. (The display will not easily return to zero if the
auto-zero time is too long or left at the default setting.)
Time Unit Settings
Proximity
sensor
Setting
Rotation speed (rpm) = f × 60 × a
f: Input pulse frequency (No. of pulses per second)
a: Prescale value
If there are 5 pulses per rotation, then
a = 1/5 (= 0.2 = 2 × 10-1)
and an accurate rotation speed (rpm) can be calculated.
-1
The actual setting is X = 2.0000 (mantissa) and Y = 10 (exponent).

Wiring Precautions
Mounting Method
• For terminal blocks, use the crimp terminals suitable for M3 screws.
• Tighten the terminal screws to the recommended tightening torque
of approx. 0.5 N·m.
• To prevent inductive noise, separate the wiring for signal lines from
that for power lines.
1. Insert the K3HB into the mounting cutout in the panel.
2. Insert watertight packing around the Unit to make the mounting
watertight.

place.
Unit Stickers (included)

• No unit stickers are attached to the Digital Indicator.
• Select the appropriate units from the unit sticker sheets provided.
LCD Field of Vision
The K3HB is designed to have the best visibility at the angles shown
in the following diagram.

K32-P1
If the rubber packing is lost or damaged, it can be ordered
using the following model number: K32-P1.
(Depending on the operating environment, deterioration,
contraction, or hardening of the rubber packing may occur and
so, in order to ensure the level of waterproofing specified in
NEMA4, periodic replacement is recommended.)
Note: Rubber packing is provided with the Controller.
