REXROTH繼電器天津總經(jīng)銷                                                                                                   REXROTH繼電器一般由鐵芯、線圈、銜鐵、觸點(diǎn)hunag片等組成的。只要在線圈兩端加上一定的電壓，線圈中就會(huì)流過一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會(huì)在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)（常開觸點(diǎn)）吸合。當(dāng)線圈斷電后，電磁的吸力也隨之消失，銜鐵就會(huì)在彈簧的反作用力返回原來的位置，使動(dòng)觸點(diǎn)與原來的靜觸點(diǎn)（常閉觸點(diǎn)）吸合。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。對(duì)于繼電器的"常開、常閉"觸點(diǎn)，可以這樣來區(qū)分：繼電器線圈未通電時(shí)處于斷開狀態(tài)的靜觸點(diǎn)，稱為"常開觸點(diǎn)"；處于接通狀態(tài)的靜觸點(diǎn)稱為"常閉觸點(diǎn)"。                                                                                                                    R901107086  HED8OH-2X/50K14AS
