Rated coil voltage
Note: 1.
When ordering, add the rated coil voltage to the model number
.
Example: G2R-1A 12 VDC
2. OMRON has also prepared the above relays with AgSnIn contacts, which are more tolerant of large inrush currents and
physical
movement compared with relays with standard contacts. When ordering, add “-ASI” to the model number
.
Example: G2R-1A-ASI
3. Standard,
NO contact type relays are TV
-3 class products in accordance with the TV standards
of the UL/CSA. Models with
AgSnIn contacts are TV-5 class products.
Example: G2R-1A-ASI
When ordering a TV
-8 class model, insert “-TV8” into the model number as follows:
Example: G2R-1A-E–ASI–TV8

BEAB approval relates to High Capacity type only

Precautions
Mounting
When
mounting a
number of relays on a PCB, be sure to provide a
minimum mounting space of 5 mm between the
two juxtaposed re
-
lays
as shown below
.
5
mm min.
5 mm min.
The above minimum mounting space is necessary due to mutual
thermal interference generated by the relays. This restriction may
be
ignored, however
, depending on the operating conditions of
the
relays.
Consult OMRON for details.
There
is no restriction on the mounting direction of each relay on the
PCB.
When using this circuit, confirm the set and reset states and then
take
into account the circuit constant.
