产品介绍
行程开关又称限位开关,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,使运动机械按一定位置或行程自动停止、反向运动、变速运动或自动往返运动等。 

    在电气控制系统中,位置开关的作用是实现顺序控制、定位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。

    在实际生产中,将行程开关安装在预先安排的位置,当装于生产机械运动部件上的模块撞击行程开关时,行程开关的触点动作,实现电路的切换。因此,行程开关是一种根据运动部件的行程位置而切换电路的电器,它的作用原理与按钮类似。

    行程开关广泛用于各类机床和起重机械,用以控制其行程、进行终端限位保护。在电梯的控制电路中,还利用行程开关来控制开关轿门的速度、自动开关门的限位,轿厢的上、下限位保护。

    行程开关可以安装在相对静止的物体(如固定架、门框等,简称静物)上或者运动的物体(如行车、门等,简称动物)上。当动物接近静物时,开关的连杆驱动开关的接点引起闭合的接点分断或者断开的接点闭合。由开关接点开、合状态的改变去控制电路和机构的动作。适用于交流50Hz。电压至380V电流至3A的控制电路中,作控制机床工作行程之用。
