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* (at 20°C)	Release voltage* (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)
6 V DC	Max. 70% V of rated coil voltage (Initial)	Min. 5% V of rated coil voltage (Initial)	320 mA	18.8 Ω	1,920 mW	110% V of rated coil voltage
9 V DC			213 mA	42.2 Ω
12 V DC			160 mA	75 Ω
15 V DC			128 mA	117 Ω
24 V DC			80 mA	300 Ω
