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.

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. 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.

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. GOOD NO GOOD 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. All Rights Reserved © COPYRIGHT Panasonic Electric Works Co., Ltd.
