Home appliances About Cdfree contacts We have introduced Cadmium free type products to reduce Environmental Hazardous Substances. (The suffi F should be added to the part number) (Note: The Suffi F is required only for Form A contact type. The 2 Form A and Form A Form B contact type is originally Cadmium free, the suffi F is not required.) Please replace parts containing Cadmium with Cadmiumfree products and evaluate them with your actual application before use because the life of a relay depends on the contact material and load.

NOTES. Soldering should be done under the following conditions: 250 C 82 F within 0s 300 C 572 F within 5s 350 C 2 F within 3s Soldering depth: 2/3 terminal pitch 2. Eternal magnetic field Since DK relays are highly sensitive polarized relays, their characteristics will be affected by a strong eternal magnetic field. Avoid using the relay under that condition. 3. When using, please be aware that the a contact and b contact sides of Form A and Form B types may go on simultaneously at operate time and release time.

FIXING AND REMOVAL METHOD. Match the direction of relay and socket. 3. Remove the relay, applying force in the direction 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.. In case there is not enough space to grasp the relay with fingers, use screwdrivers in the way shown in the illustration. Notes:. Eercise 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. GOOD NO GOOD 9 ds_a03_en_dk: 203D
