■Engineering Data
■Dimensions (Unit: mm)
■Approved Standards
The approved rated values for international standards are different to the individually specified characteristic values. Be sure to confirm
that required standards are satisfied before actual use.
UL Recognized: (File No. E41643)
CSA Certified: (File No. LR31928)
EN/IEC Certified Model
(Approval/No. 40015012)
■Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
●Differences with the G2R
The G2RG-2A4 has the same terminal arrangement as the
G2R-2A4 but the switching capacity and electrical endurance are
different. Confirm that correct operation is possible in the actual
operating conditions before using in applications.

●Maximum Switching Capacity ●Ambient Temperature vs
Maximum Coil Voltage
Note. The maximum allowable voltage is the maximum
possible value of the voltage that can be applied
to the relay coil.
●Shock Malfunction
Sample: G2RG-2A4 24 VDC
Number of Relays: 5 pcs
Test conditions: Shock is
applied in ±X, ±Y, and ±Z
directions three times each with
without energizing the Relays to
check the number of
malfunctions.
Requirement: 200 m/s
