DK RELAYS
FEATURES
TYPICAL APPLICATIONS
1. Compact with high capacity
High capacity switching in a small
package: 1 Form A, 10 A 250 V AC;
1 Form A 1 Form B and 2 Form A, 8 A
250 V AC.
1. Switching power supply
2. Power switching for various
OA equipment
3. Control or driving relays for
industrial machines (robotics,
numerical control machines, etc.)
4. Output relays for programmable
logic controllers, temperature
controllers, timers and so on.
5. Home appliances
2. High sensitivity: 200 mW nominal
operating power
3. High breakdown voltage
Independent coil and the contact
structure improves breakdown voltage.

We have introduced Cadmium free type
products to reduce Environmental
Hazardous Substances.
Conforms with FCC Part 68
(The suffix “F” should be added to the
part number)
4. Latching types available
5. Sealed construction allows
automatic washing.
(Note: The Suffix “F” is required only for
1 Form A contact type.The 2 Form A and
1 Form A 1 Form B contact type is
originally Cadmium free, the suffix “F” is
not required.)
Please replace parts containing
Cadmium with Cadmium-free products
and evaluate them with your actual
application before use because the life of
a relay depends on the contact material
and load.
6. Sockets are also available
7. Complies with safety standards
Complies with Japan Electrical Appliance
and Material Safety Law requirements for
operating 200 V power supply circuits,
and complies with UL, CSA, and TÜV
safety standards.

NOTES
1. Soldering should be done under the
following conditions:
3. When using, please be aware that
the a contact and b contact sides of 1
Form A and 1 Form B types may go on
simultaneously at operate time and
release time.
250°C 482°F within 10s
300°C 572°F within 5s
350°C 662°F within 3s
Soldering depth: 2/3 terminal pitch
2. External magnetic field
Since DK relays are highly sensitive
polarized relays, their characteristics will
be affected by a strong external magnetic
field. Avoid using the relay under that
condition.
For Cautions for Use, see Relay Technical Information.

FIXING AND REMOVAL METHOD
1. Match the direction of relay and socket.
3. Remove the relay, applying force in the
direction shown below.
4. In case there is not enough space to
grasp relay with fingers, use screwdrivers
in the way shown below.
2. Both ends of the relay are to be
secured firmly so that the socket hooks
on the top surface of the relay.
Notes: 1. Exercise care when removing relays. If
greater than necessary force is applied at
the socket hooks, deformation may alter the
dimensions so that the hook will no longer
catch, and other damage may also occur.
2. It is hazardous to use IC chip sockets.
