8.56.AA.62為(wei)單動(dong)(dong)(dong)作(zuo)開放式線(xian)(xian)性電磁。只要(yao)線(xian)(xian)圈(quan)通(tong)(tong)電，柱(zhu)(zhu)塞(sai)(sai)就可(ke)以(yi)開啟電源(yuan)并保持。關(guan)閉電源(yuan)，柱(zhu)(zhu)塞(sai)(sai)被釋放，并通(tong)(tong)過外(wai)力(li)(li)返(fan)回到(dao)起始位置(zhi)。當柱(zhu)(zhu)塞(sai)(sai)運動(dong)(dong)(dong)開始時和(he)當電磁配(pei)有連續(xu)額定線(xian)(xian)圈(quan)時，實現較小的力(li)(li)。柱(zhu)(zhu)塞(sai)(sai)處于起始位置(zhi)（柱(zhu)(zhu)塞(sai)(sai)外(wai)側，推力(li)(li)銷在內(nei)部），由外(wai)力(li)(li)釋放或(huo)維(wei)持。線(xian)(xian)圈(quan)通(tong)(tong)電，柱(zhu)(zhu)塞(sai)(sai)關(guan)閉停止(zhi)，拉動(dong)(dong)(dong)聯接機構，推力(li)(li)銷推出。關(guan)閉電源(yuan)，柱(zhu)(zhu)塞(sai)(sai)和(he)推力(li)(li)銷通(tong)(tong)過外(wai)力(li)(li)返(fan)回到(dao)起始位置(zhi)。
