style="text-indent:25px">永磁限位開關工作原理：永磁限位開關由靜件磁性開關和動件控制磁鋼組成，采用磁感應原理，直接吸合干簧管接點，以實現(xiàn)對外接電路的通斷控制。性能可靠，安裝方便，動作靈敏，使用壽命長，本產品有礦用一般型《MA》標志.由于本開關實質上是一種干簧管為主體的無接觸感應式磁控開關，無需附加電源，完全克服了國內普遍使用的機械碰撞開關存在的接觸不良、不可靠、易損壞等特點。該產品具有性能穩(wěn)定、可靠性高、抗震動性強、裝置方便、使用壽命長等優(yōu)點，其性能達到了國外同類產品水平，是煤礦行程控制的換代產品，也是引進設備的理想代用產品。永磁限位開關安裝條件：1.進線嘴安裝時不要向上，其它方式不受限制。2.使用時應避免非激勵磁場的影響。</p><p style="text-indent:25px">限位開關的結構：極限限位開關是防止機構動作超出設計范圍而發(fā)生事故的。限位開關分工作限位開關和極限限位開關，工作限位開關是用來給出機構動作到位信號的。工作限位開關安裝在機構需要改變工況的位置，開關動作后，給出信號，進行別的相關動作。極限限位開關安裝在機構動作的遠端，用來保護機構動作過大出現(xiàn)機構損壞。限位開關（也叫行程開關）是有觸點開關，適合單方向位置檢測，由于有觸點，相對壽命要短但是，隨著科技的發(fā)展，限位開關觸點材料的不斷更新，其可通斷次數(shù)也非常高，就不用擔心其壽命因素了。限位開關是3D打印機確定位置的重要傳感器。</p><div

style="text-indent:25px">限位開關的構成：接點金Au抗腐蝕性非常優(yōu)越，用于微小負載。因為其質地較柔軟(維氏硬度HV25～65)，因此較易黏著(接點黏著)，并且在接點接觸力較大的情況下接點容易凹陷。金、銀合金AuAg90％金、10％銀的合金抗腐蝕性非常優(yōu)越，硬度為HV30～90，比金高，因此廣fan用于微小負載用開關。白金、金、銀合金PGS69％金、25％銀、6％白金的合金抗腐蝕性非常優(yōu)越，硬度也與金銀合金相同，廣fan用于微小負載用開關。稱為作“1號合金”。銀、鈀合金AgPd抗腐蝕性較好，但較易吸附有機氣體生成聚合物。50％銀、50％鈀的情況下，硬度為HV100～200。銀Ag導電率、熱傳導率在金屬中是大的。雖然表現(xiàn)出較低的接觸電阻，但其缺點是，在硫化氣體的環(huán)境中較易生成硫化膜，在微小負載區(qū)域較易產生接觸不良。硬度為HV25～45。多用于一般負載用開關。銀、鎳合金AgNi90％銀、10％鎳的銀、鎳合金導電率與銀接近，在抗電弧、抗熔化方面表現(xiàn)優(yōu)良。硬度為HV65～115。銀、銦、錫合金AgInSn硬度、熔點較高，抗電弧性優(yōu)越，不易熔化或轉移。陜西防爆限位開關APL</p><p
