ORDERING INFORMATION

1a 10 A,1a1b/2a 8 A small

polarized power relays

DK RELAYS

VDE

FEATURES

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.

2. High sensitivity: 200 mW nominal

operating power

3. High breakdown voltage

Independent coil and the contact

structure improves breakdown voltage.

Conforms with FCC Part 68

4. Latching types available

5. Sealed construction allows

automatic washing.

6. High insulation resistance

Creepage distance and clearances

between contact and coil: Min. 8 mm

DK2a-L2: 6.8 mm

DK1a1b-L2: 6.8 mm

7. Sockets are available

8. 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.

TYPICAL APPLICATIONS

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

About Cd-free contacts

We have introduced Cadmium free type

products to reduce Environmental

Hazardous Substances.

(The suffix “F” should be added to the

part number)

(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.
