Omron G4Q-211A, G4Q-212S Datasheet
208 Ratchet Relay G4Q
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 mechanism.
• Satisfies dielectric strength of 2,000 VAC.
• Low power consumption.
(AC: approx. 6.4 VA; DC: approx. 3.9 W)

Specifications
■ 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.
