8. Mirror contact mechanisms (Compliant with EN60947-4-1
mirror contact)
3. Compact size and low operating power
W: 30 × L: 36 × H: 40 mm W: 1.181 × L: 1.417 × H: 1.575 inch
Operating power: 1,880 mW (holding power: 170 mW)
Detection of main contact welding makes it possible to
construct a safety circuit.
• Designed so that Form A contact and Form B contact will
not close at the same time.
• When Form A contact welded, Form B contact gap of at
least 0.5 mm .020 inch is maintained.
4. Reduced coil holding voltage contributes to saving
energy of equipment
The coil holding voltage can be reduced up to 30%V of the
nominal coil voltage. This equals to operating power of
approximately 170 mW, which contributes equipment energy
savings.
* Form B contact, when used to monitor the condition of Form A contact, can be
used exclusively as an auxiliary contact.
* Coil holding voltage is the coil voltage after 100 ms from the applied nominal coil
voltage.
5. Contact gap: 3.2 mm .126 inch (VDE0126 compliant)
Compliant with European photovoltaic standard VDE0126

actual load.
*2. Wave is standard shock voltage of ±1.2×50μs according to JEC-212-1981
*3. Coil holding voltage is the coil voltage after 100 ms from the applied nominal coil voltage.
*4. Release time will lengthen if a diode, etc., is connected in parallel to the coil. Be sure to verify operation under actual conditions.
*5. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*6. Regarding Form B contact, only the 2 Form A 1 Form B type applies.

NOTES
1. For cautions for use, please refer to our web site.
(https://www3.panasonic.biz/ac/e/control/relay/cautions_use/index.jsp)
2. When coil holding voltage controlled by PWM, check coil holding voltage and operation of relay under the actual
condition.
3. Usage, transport and storage conditions
1) Temperature:
–40 to +55°C –40 to +131°F (When applied coil holding voltage is 30% to 110%V of nominal coil voltage)
–40 to +85°C –40 to +185°F (When applied coil holding voltage is 30% to 60%V of nominal coil voltage or storage)
2) Humidity: 5 to 85% RH (Not freezing and condensing at low temperature)
In addition the humidity range depends on temperature. The allowable ranges are as follows;
3) Air pressure: 86 to 106 kPa
Allowable range of temperature and humidity for operation, transport and storage.

4. Solder and cleaning conditions
1) Please obey the following conditions when soldering automatically.
(1) Pre-heating: within 120°C 248°F (solder surface terminal portion) and within 120 seconds
(2) Soldering iron: 260°C±5°C 500°F±41°F (solder temperature) and within 10 seconds (soldering time)
2) In case of manual soldering, following conditions should be observed.
• Max. 270°C 518°F (solder temperature) within 10 seconds (soldering time)
• Max. 350°C 662°F (solder temperature) within 5 seconds (soldering time)
* Effects of soldering heat on the relays vary depending on the PC board. So please confirm actual soldering condition with the PC
board used for assembling.
3) Do not clean this relay by immersion, since the relay is not sealed.
Also, be careful not to allow flux to overflow above the PC board or enter the inside of the relay.
