800T-N6104KF4B产品详情
限位开关就是用以限定机械设备的运动****限位置的电气开关。限位开关有接触式的和非接触式的。接触式的比较直观,机械设备的运动部件上,安装上行程开关,与其相对运动的固*上安装****限位置的挡块,或者是相反安装位置。当行程开关的机械触头碰上挡块时,切断了(或改变了)控制电路,机械就停止运行或改变运行。由于机械的惯性运动,这种行程开关有一定的“超行程”以保护开关不受损坏。非接触式的形式很多,常见的有干簧管、光电式、感应式等,这几种形式在电梯中都能够见到。当然还有更多的****形式。限位开关是一种常用的小电流主令电器。利用生产机械运动部件的碰撞使其触头动作来实现接通或分断控制电路,达到一定的控制目的。通常,这类开关被用来限制机械运动的位置或行程,使运动机械按一*置或行程自动停止、反向运动、变速运动或自动往返运动等。在电气控制系统中,限位开关的作用是实现顺序控制、*控制和位置状态的检测。用于控制机械设备的行程及限位保护。构造:由操作头、触点系统和外壳组成。

Limit switch working limit switch and limit switch, limit switch is used to give the work mechani* of action in place signal. Limit switch is to prevent the agency beyond the scope of design and accident. Work limit switches are installed in the *ition of the mechani* to change the conditi*witch, signal is given, for other related acti*. Limit switch installed in the mos*stal moveme*f mechani*, to protect the mechani* of action is too large there is damaged.
The main part of the switch is com*ed of the following materials
Mark of part*aterials
Contact Au corrosion resistance is superior, for *all load. Because of its soft texture (Vivtorinox hardness HV25 ~ 65), it is easy to adhesion (contact adhesive), and in the contact force under the condition of large contact easy to sag.
Alloy of gold, silver, 10% silver gold alloy AuAg 90% corrosion resistance is very good, hardness is HV30 ~ 90, higher than the gold, so it is widely used in *all load switch.
Platinum, gold, silver, 69% gold, 25% silver alloy PGS, 6% platinum alloy, corrosion resistance is very good, hardness is also the same with gold and silver alloy, widely used in *all load switch. Known as the "No. 1 alloy".
Silver palladium alloy AgPd, good corrosion resistance, but it is easy to adsorb organic gas generation polymer. 50% silver, 50% case of palladium, hardness is HV100 ~ 200.
Silver Ag electrical conductivity, thermal conductivity is one of the largest in the metal. Although the exhibit lower contact resistance, but the drawback*easy to generate sulfide film in sulfide gases in the environment, in the *all load area is easy to produce bad. Hardness is HV25 ~ 45. For more general load switch.
Silver, nickel alloy AgNi 90% silver, 10% silver, nickel and silver nickel alloy electric conductivity in close, arc resistance, excelle*esistance to melting. Hardness is HV65 ~ 115.
Silver, indium, tin alloy AgInSn hardness, high melting point, excellent arc resistance, not easy to melt or transfer.
The movable spring, the movable plate spring with phosphor bronze C5210 rolling resistance, fatigue resistance and corrosion resistance. H*e carried out annealing treatment. If the spring critical value (Kb0.075) of C5210-H i*ore than 40kgf/mm2, C5210-EH i*ore than 47kgf/mm2, the lower, are widely used in the *all micro switch.

凡*人之所以起者,以上之不贵义,不敬义也。夫义者,所以限禁人之为恶与 *者也。今上不贵义,不敬义,如是,则天下之人百姓,皆有弃义之志,而有趋* 之心矣,此*人之所以起也。且上者下之师也,夫下之和上,譬之犹响之应声,影 之像形也。故为人上者,不可不顺也。夫义者,内节于人,而外节于万物者也;上 安于主,而下调于民者也;内外上下节者,义之情也。然则凡为天下之要,义为本, 而信次之。古者禹汤本义务信而天下治,桀纣弃义倍信而天下乱。故为人上者,必 将慎礼义,务忠信,然后可。此君人者之大本也。堂上不粪,则郊草不瞻旷芸*扞乎胸,则目不见流矢;拔戟加乎首,则十指不辞断;非不以此为务也,疾养缓 急之有相先者也。
