SPECIFICATIONS

Contact

(1) Standard type (12V coil voltage)

#1 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.

(2) Standard type (24V coil voltage)

All other specifications are the same as those of standard type (12V coil voltage)

(3) Heat resistant type (12V, 24V coil voltage)

All other specifications are the same as those of standard type (12V coil voltage)

PC board type

* Current value in which carry current is possible when the coil temperature is 180°C 356°F.
