For cautions for use, please read “GENERAL APPLICATION GUIDELINES” on page B-1.** ## **2. Soldering conditions** Please obey the following conditions when soldering automatically. 1) Preheating: Within 120°C 248°F and within 120 seconds 2) Soldering iron: 260°C±5°C 500°F±41°F and within 6 seconds ## **3. Cleaning** For automatic cleaning, the boiling method is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that a fluorinated hydrocarbon or other alcoholic solvents be used. ## **4. External magnetic field** Since DSP relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition. ## **5. Coil operating power** Pure DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. **6. When using, please be aware that the a contact and b contact sides of 1 Form A 1 Form B type may go on simultaneously at operate time and release time.** Panasonic Corporation Automation Controls Business Division industrial.panasonic.com/ac/e/ ASCTB180E 201402-T © Panasonic Corporation 2014 –6– ## **ACCESSORIES** ## DSP RELAYS PC BOARD SOCKETS ## **TYPES** |**TYPES**||| |---|---|---| ||Part No.|| |Product name|For Single side stable|For 2 coil latching| |For DSP1a|DSP1a-PS|DSP1a-PSL2| |For DSP1a, DSP1, DSP2a|DSP2a-PS|DSP2a-PSL2| Standard packing: Carton: 50 pcs.; Case: 500 pcs. ## **TYPES AND APPLICABLE RELAYS** |Type No.

## **FIXING AND REMOVAL METHOD** 1. Match the direction of relay and socket. 3. Remove the relay, applying force in the direction shown below. a 4. In case there is not enough space for finger to pick relay up, use screw drivers in the way shown below. 2. Both ends of relays are fixed so tightly that the socket hooks on the top surface of relays. 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.
