G5NB PCB Power Relay

A Miniature Relay with 1-pole 3A/5A Switching Capability and 10 kV Impulse Withstand Voltage

  • Highly efficient magnetic circuit for high sensitivity (200 mW).
  • Small, yet provides 10-kV impulse withstand voltage (between coil and contacts).
  • Standard model conforms to UL/CSA/VDE standards.
  • Satisfies EN61010 reinforced insulation requirements.
  • IEC/EN 60335-1 conformed. (-HA Model)
  • Enable Smaller PCB Designs
    PCB Power Relays Type G5NB, Type G5Q
    Introduction of G5NB and G5Q

    Circuit designers face the constant challenge of shrinking PCB designs.
    Now, with OMRON G5NB and G5Q slim power relays, small PCB designs can be easier to create than ever.

Precautions

Correct Use

Coil Voltage Reduction (Holding Voltage) after Relay Operation
  • If the coil voltage is reduced to the holding voltage after Relay operation, first apply the rated voltage to the coil for at least 100 ms, as shown below.
  • A voltage of at least 40% of the rated voltage is required for the coil holding voltage. Do not allow voltage fluctuations to cause the coil holding voltage to fall below this level.
