high-withstand
voltage relay with no contact chatter-
ing for momentary voltage drops up to 50% of rated voltage.
• UL Class B construction standard.
• Wide-range AC-activated coil that handles 100 to 120 VAC or 200
to 240 VAC at either 50 or 60 Hz.
• Miniature size for maximum switching capacity, particularly for
inductive loads.
• Flame resistant materials (UL94V-0-qualifying) used for
all insulation material.
• Quick-connect, screw, PCB terminals and DIN track mounting available.
• Conforms to UL, CSA, TUV and meets IEC 950.
• Safety design with contact gap of 3 mm.
• RoHS Compliant. Note: Accessories: E-bracket, Adapter, Front-connecting socket
and Cover are sold separately.
Ordering Information
To Order: Select the part number and add the desired coil voltage rating (e.g., G7L-1A-T-CB-AC100/120).
Note: 1. E bracket or socket must be used for mounting (part number R99-07G7L). Refer to “Accessories” section for options and part numbers.
2. For VDE approved versions, please consult OMRON.

■Contact Data
Note: 1. P level: λ60 =0.1x10
-6 operation.
2. When using B-series (screw) products, since the screw diameter of the contact terminal is M4, be careful that the contact current should be 20 A or less
according to JET standard (electrical appliance and material control law of Japan).

DC operating coil AC operating coil Note: 1. The ratio of rated voltage between 100 to 120 VAC are values
measured on the basis of 100 VAC
2. When driving a transistor, check the leakage current and connect
a bleeder resistor if necessary.
3. The AC coil is provided with a built-in full-wave rectifier. If a triac,
such as an SSR, drives the G7L, the G7L may not release. Be sure
to perform a trial operation with the G7L and the triac before ap-
plying them to actual use.

■Coil Data
AC
DC
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 inductances shown above are reference values.
3. Performance characteristic data are measured at a coil temperature of 23°C.
4. The maximum allowable coil voltage refers to the maximum value in a varying range of operating power voltage, measured at ambient
temperature 23°C.
5. The “to” (for example “100 to 120”) represents a range of rated voltages.
■Characteristics
Note: Data shown are of initial value.
Note: 1. Measurement conditions: 5 VDC, 1 A, voltage drop method.
2. Measurement conditions: Rated operating voltage applied, not including contact bounce, @ 23°C.
3. Measurement conditions: The insulation resistance was measured with a 500-VDC megohmeter at the same locations as the dielectric
strength was measured.

Precautions
■Correct Use
Handling
To preserve initial performance, do not drop or otherwise subject the
power relay to shock.
The case is not designed to be removed during normal handling and
operation. Doing so may affect performance.
Use the power relay in a dry environment free from excessive dust,
SO2,H
2S, or organic gas.
Do not allow a voltage greater than the maximum allowable coil volt-
age to be applied continuously.
Do not use the power relay outside of specified voltages and currents.
Do not allow the ambient operating temperature to exceed the speci-
fied limit.
Installation
Although there are not specific limits on the installation site, it should
be as dry and dust-free as possible.
Using in an atmosphere of high humidity and corrosive gas may
deteriorate its performance characteristic caused by condensation or
corrosive products, resulting in failure or burn damage of the Relay.
PCB terminal-equipped relays weigh approximately 100 g. Be sure
that the PCB is strong enough to support them. We recommend
dual-side through-hole PCBs to reduce solder cracking from heat
stress.
Relays with test buttons must be mounted facing down. Be careful
not to touch the test button accidentally. Doing so may turn on the
contact.
Be sure to use the test button for test purposes only (with test-button
models). The test button is used for Relay circuit tests, such as circuit
continuity tests. Do not attempt to switch the load with the test button.
Soldering PCB Terminals
Do not perform automatic soldering, but solder manually.
Do not wash down the entire Relay because it does not have an air-
tight construction.
Connecting
Refer to the following table when connecting a wire with a crimp style
terminal to the G7L.
Allow suitable slack on leads when wiring and do not apply excessive
force to the terminals.
Tightening torque;
Coil: 0.78 to 1.18 N·m
Contacts: 0.98 to 1.37 N·m
When connecting with screws, if the screws are not sufficiently tight-
ened, the lead wire can become detached and may lead to abnormal
heating or fire caused by faulty contact.
Do not apply excessive force when mounting or dismounting the
faston receptacle. Insert and remove terminals carefully, one at a
time. Do not insert terminals at an angle, or insert / remove multiple
terminals at the same time.
Do not connect to the terminals by soldering. Use #250 faston or
positive-lock connectors;
*the numbers shown in parentheses are for air-feeding.
Note: 1. The current should be 25A when using receptacle terminals.
2. Use receptacle terminals or positive housing for cable wiring.
Mounting
Top Bracket Type
Mounting torque; 0.98 N·m
Tighten with to M4 screws when mounting.
DIN Track Mounting Adapter and Front-Connecting Socket
The DIN Track Mounting Adapter and Front-connecting Socket can
be mounted on the G7L with just one hand and dismounted with
ease using a screwdriver.
To support the G7L mounted on a DIN Track Mounting Adapter or
Front-connecting Socket, use the PFP-M End Plate. Put the End
Plate onto the DIN Track Mounting Adapter or Front-connecting
Socket so that the surface mark of the End Plate faces upwards.
Then tighten the screw of the End Plate securely with a screwdriver.
Screw Mounting
Screw-mount the DIN Track Mounting Adapter or Front-connecting
Socket securely after opening screw mounting holes on them.
When cutting or opening holes on the panel after the Front-connect-
ing Socket is mounted, take proper measures so that the cutting
chips will not fall onto the Relay terminals. When cutting or opening
holes on the upper part of the panel, mask the Front-connecting
Socket properly with a cover.
Operating Coil
•As a rule, either a battery or a DC power supply with a maximum
5% ripple is used for the operating voltage for DC relays. Before
using a rectified AC supply, confirm that the ripple is not greater
than 5%. Ripple greater than this can lead to variations in the oper-
ating and reset voltages.
As excessive ripple can generate beats, the insertion of a
smoothing capacitor is recommended as shown below.
•When driving a transistor, check the leakage current and connect a
bleeder resistor if necessary.
•Momentary voltage drops on coil input voltage should not exceed
one second duration after contact mating with no shock or vibra-
tion.
