Ratchet Relay
G4Q
Unique Ratchet Mechanism Assures Positive
Alternate Transfer/Switching Operation
• Each contact in the double-pole contact mechanism performs
alternate make-brake operation at each pulse input and is thus
ideal for alternate operation or transfer/switching operation of a
motor.
• Positive operation is assured due to the unique ratchet mecha-
nism.
• Satisfies dielectric strength of 2,000 VAC.
• Low power consumption.
(AC: approx. 6.4 VA; DC: approx. 3.9 W)

■Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/–20% for AC rated current and
±15% for DC coil resistance.
2. The AC coil resistance values are for reference only.
3. Performance characteristic data is measured at a coil temperature of 23°C.
4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of 23°C and not continuously.
5. The AC power consumption is measured at 60 Hz.

■Characteristics
Note: 1. The data shown above are initial values.
2. The contact resistance was measured with 0.1 A at 5 VDC using the voltage drop method.
3. The operate time was measured with the rated voltage imposed with any contact bounce ignored at an ambient temperature of 23°C.
4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for checking the dielectric
strength.
5. The electrical endurance was measured at an ambient temperature of 23°C.
6. This value was measured at a switching frequency of 60 operations per minute. The value in parentheses is for the cased model.

Operation
Note: When a pulse for application to the coil is used, such a pulse
should have a width of 100 ms or more. If a pulse is applied with
a width less than the operate time, the cam may fail to rotate
fully.

Note: All units are in millimeters unless otherwise indicated.

Precautions
Refer to page 11 for general precautions.
■Surface Mounting Socket
