  • The values given above are initial values.
  • *The figures for the operating characteristics are for a coil temperature of +23°C.

*1. Measurement conditions: 5 V DC, 10 mA, voltage drop method.
*2. Measurement conditions: rated voltage operation. Ambient temperature conditions: +23°C. Bounce time not included.
*3. Measured with a 500 V DC ohmmeter at the same places that the dielectric strength was checked.
*4. When using a P7S socket, the dielectric strength between coil contacts/different poles is 2,000 V AC, 50/60 Hz for 1 min.
*5. The coil refers to terminals 0-1, pole 1 refers to terminals 13−14, pole 2 refers to terminals 23−24, pole 3 refers to terminals 33−34, pole 4 refers to terminals 41−42 or 43−44, pole 5 refers to terminals 51−52, and pole 6 refers to terminals 61−62.
*6. The durability is for an ambient temperature of 15 to +35°C and an ambient humidity of 25% to 75% RH.
*7. AC15: cosφ = 0.3 mm, DC13: L/R = 96 ms inductive load.
*8. This value is based on a switching frequency of 60 operations/min.
