VT3□□系列直流（DC）型电磁阀配线时，有极性吗？

电磁阀的电源线为红色与黑色时，红色接正（+）、黑色接负（-）。DIN型端子以及插座型端子等没有电源线的情况下，1号端子接正（+）、2号端子接负（-）。除此之外，不分极性。

SMC电磁阀通过控制器切换脉冲的电极触点来改变电磁阀的开关状态，当控制器发出电脉冲时，驱动阀芯克服永磁力产生上下移，阀瓣到位后在永磁作用下处于自保持状态，同时用屏蔽技术，防止外界干扰。

日本SMC电磁阀线圈通电。此时，电磁阀铁芯在电磁力的作用下克服回复弹簧作用力移到单管端，关闭单管端出口，双管端出口处于开启状态，制冷剂从电磁阀双管端出口管流向冷冻室蒸发器流回压缩机，实现制冷循环。
