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.

When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction.

This relay is not sealed, therefore, immersion may cause failure. Be careful that flux does not overflow onto the PC board or penetrate inside the relay.

When using automatic soldering, the following conditions are recommended

1) Preheating: 120°C 248°F, within 120 Sec (PC board solder surface)
2) Soldering: 260°C±5°C 500°F±41°F, within 6 Sec

1) Attach directly to the chassis or use a DIN rail.

2) Refer to the figure below for applicable wire-pressed terminals.
(You cannot use round type wire-pressed terminals.)

1) If the relay has been dropped, the appearance and characteristics should always be checked before use.

2) The switching lifetime is defined under the standard test condition specified in the JIS* C 5442-1996 standard (temperature 15 to 35°C 59 to 95°F, humidity 25 to 75%). Check this with the actual product as it is affected by the coil driving circuit, load type, activation frequency, activation phase, ambient conditions and other factors. Also, be especially careful with loads such as those listed below.

Please see the following countermeasure examples:

3) For secure operations, nominal coil voltage should be applied. In addition, please note that pick-up and drop-out voltage will vary according to the ambient temperature and operating conditions.

4) Heat, smoke, and/or fire may occur if the relay is used outside the allowable ranges for the coil ratings, contact ratings, operating cycle lifetime, and other specifications. Therefore, do not use the relay if these ratings are exceeded. Also, make sure that the relay is wired correctly.

5) Incorrect wiring may cause false operation or generate heat or flames.

6) Check the ambient conditions when storing or transporting the relays and devices containing the relays. Freezing or condensation may occur in the relay causing damage. Avoid exposing the relays to heavy loads, or strong shock and vibration.

1) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay:

2) Condensation
Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of the relay insulation.

3) Freezing
Condensation or other moisture may freeze on the relay when the temperatures is lower than 0°C 32°F. This causes problems such as sticking of movable parts or operational time lags.

4) Low temperature and low humidity At low temperature, low humidity environments, the plastic becomes brittle. Please note corrections.
