Coil data

  • Operating characteristics such as ‘Operate voltage’ and ‘Release voltage’ are influenced by mounting conditions, ambient temperature, etc.
    Therefore, please use the relay within ± 5% of rated coil voltage.
  • ‘Initial’ means the condition of products at the time of delivery.

*1This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.
*2Wave is standard shock voltage of ±1.2×50μs according to JEC-212-1981
*3The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value.
