• Description: Electromagnetic Counter
• Manufacturer: Omron Corporation

Safety Precautions
Mounting/Connection
Whenever possible, install the Counter at an environment where it is
not subject to heavy vibration, dust, and corrosive gases. When
mounting the Counter on a panel with screws, do not apply excessive
force on the screws when tightening, but be sure to tighten the
screws securely. To flush-mount the Counter (a -Y model), insert it
into the cutout on the mounting panel, until its class catch securely.
Use lead wires approximately 250 mm long. Do not stretch the leads
with excessive force. Insulate the leads with insulation tape, etc.
When mounting the Counter using its screw holes, use screws that fit
the holes properly. Also when determining the length of the screws,
take the thickness of the mounting panel into consideration.
Supply Voltage
The Counter operates on a voltage 85% to 110% of the rated supply
voltage. If the supply voltage exceeds or drops below this range, the
Counter may malfunction. The DC models can operate with a ripple
factor of 48% or less; so, they can be driven by a single-phase, full-
wave rectified power source, whose waveform is shown below.
Count Signal
(1) Contact Input
When using a contact input device to input the count signal, carefully
select the input device. Use the current capacity and life of the
contact of the input device as criteria for the selection. It is
recommended to connect a protective circuit across the contacts of
the input device, or a surge absorber across the Counter’s coil, so
that surges are absorbed and the life of the contacts are extended.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.

(2) Solid-state Input
When a solid-state input device is used, a surge absorber is
necessary to protect the Counter drive transistor from being
adversely affected by noises. If a diode is used as the surge
absorber, the reset time of the Counter will be prolonged and, as a
result, the Counter’s response speed will be slowed down. If an RC
network is used, the response characteristics of the Counter will be
better as compared when a diode is used, but the
counterelectromotive force cannot be completely reduced to zero.
