門(men)(men)吸也(ye)(ye)俗稱(cheng)門(men)(men)碰，也(ye)(ye)是一種(zhong)門(men)(men)頁(ye)打開后吸(xi)住定位的裝置，以防止(zhi)風吹(chui)或碰觸門(men)(men)(men)頁而(er)關閉。門(men)(men)(men)吸(xi)分為永磁(ci)門(men)(men)(men)吸(xi)和(he)電磁(ci)門(men)(men)(men)吸(xi)二種，永磁(ci)門(men)(men)(men)吸(xi)一(yi)般用(yong)在普(pu)通門(men)(men)(men)中(zhong)，只能(neng)手(shou)動控制；電磁(ci)門(men)(men)(men)吸(xi)用(yong)在防火門(men)(men)(men)等電控門窗(chuang)設(she)備(bei)，兼有手動控制(zhi)和自動控制(zhi)功能。

普通永磁門吸按安裝(zhuang)形式分墻裝式(shi)(shi)(shi)、地裝式(shi)(shi)(shi)，按材質分塑料(liao)型、金屬(shu)型；電磁門吸(xi)按不同的安(an)裝方(fang)式(shi)(shi)(shi)產品分為CT-01墻式(shi)(shi)(shi)、CT-02地式(shi)(shi)(shi)、CT-03鏈式(shi)(shi)(shi)三大類，墻式(shi)(shi)(shi)電磁門吸(xi)根據結(jie)構不同(tong)又分為標準(zhun)型(xing)(xing)、增高(gao)型(xing)(xing)、加長(chang)型(xing)(xing)、盒裝型(xing)(xing)、暗(an)裝型(xing)(xing)、長(chang)臂型(xing)(xing)等；地式(shi)電(dian)(dian)磁門吸由CT-01墻式(shi)電(dian)(dian)磁門吸和直角地面(mian)安裝支架組成；鏈(lian)式(shi)電(dian)(dian)磁門吸由CT-01墻式電(dian)磁(ci)(ci)門吸和鏈條扣件組(zu)成；由于CT-01墻式、CT-02地式、CT-03鏈式電(dian)磁(ci)(ci)門吸主體互相通(tong)用，方便用戶根據(ju)使用現(xian)場安裝(zhuang)條件來選用。
