Notes:
1. PC board assembled with dust cover type and flux tight type relays can not be washed and/or coated.
2. Dust cover type and flux tight type relays can not be used in the environment with dust, or H2S, SO2, NO2 or similar gaseous environment etc.

* The tolerance without indicating for PCB layout is always ±0.1mm.
Unless otherwise specified tolerances are:
| ≤1mm | >1mm and ≤5mm | >5mm |
| ±0.2mm | ±0.3mm | ±0.4mm |
Notice:
1. Relay is on the “reset” or “set” status when being released from stock, with the consideration of shock risen from transit and relay mounting, relay would be changed to “set” or “reset” status, therefore, when application (connecting the power supply), please reset the relay to “set” or “reset”status as required.
2. Do not energize voltage to “set” coil and “reset” coil simultaneously. Long energized time (more than 1 min) should be avoided.

APPLICATION GUIDELINES
Automatic Soldering
* Flow solder is the optimum method for soldering.
* Adjust the level of solder so that it does not overflow onto the top of the PC board.
* Unless otherwise specified, solder under the following conditions depending on the type of relay.
| Preheat time 20°C-100°C | Rising slope 20°C-120°C | Decreasing slope Peak-150°C | Welding temperature 255°C-265°C |
|---|---|---|---|
| 90±5 seconds | <3°C/s | <4°C/s | 3~5s |
Hand Soldering
* Keep the tip of the soldering iron clean.
| Solder lron | 30W or 60W |
|---|---|
| lron Tip Temperature | Approx. 350°C 662°F |
| Solder Time | Within approx. 3 seconds |
* Immediate air cooling is recommended to prevent deterioration of the relay and surrounding parts due to soldering heat.
* Although the sealed type relay can be cleaned, avoid immersing the relay into cold liquid
(such as washing solvent) immediately after soldering. Doing so may deteriorate the sealing performance.
