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.

Rated coil voltage	Operate voltage^*1 (at 20°C)	Release voltage^*1 (at 20°C)	Rated operating current (±10%, at 20°C)	Coil resistance (±10%, at 20°C)	Rated operating power	Max. allowable voltage (at 55°C)
12 V DC	Max. 75 % V of rated coil voltage (Initial)	Min. 5 % V of rated coil voltage (Initial)	333 mA	36.0 Ω	4,000 mW Holding^2: 490 mW^3	110 % V of rated coil voltage
