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.

*1	When using at 7.5 A, please refer to "GUIDELINES FOR USAGE, Max. switching current".
*2	This value is a rough indication of the lower limit at which switching is possible at micro load level. This 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.
*3	For ambient temperature, please refer to the “GUIDELINES FOR RELAY USAGE”.
