MR330-11Y-1366限位开关又称行程限位开关，用于控制机械设备的行程及限位保护。在实际中，将行程限位开关安装在预先安排的位置，当装于机械运动部件上的模块撞击行程开关时，行程限位开关的触点动作，实现电路的切换。因此，限位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。限位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，还利用行程限位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。

工作原理：

当胶带运输机现场紧急事故时,在沿线任意位置牵动系在挂耳上的钢丝绳,迫使机内凸轮转动而驱动元件开关动作,发出停机信号,达到停机效果,防止事故的扩大。

通用的安装设计使拉线开关既可安装在输送机的纵梁顶部也可安装在其两侧。 ●坚固的铸铝外壳,特殊环境可选择特殊的表面处理。 ●整体式盖板使的接线及开关调整方便简单,而不用拆卸开关。 拉线开关钢丝绳一端固定在一个固定的拉线螺栓上,另一端固定在开关臂上,钢丝绳应每3m用一个有孔螺栓支撑,开关到固定点的距离应不超过24m,两开关的距离不超过48m。当外力促使开关臂杆转动到报警位置时,触动微动开关并锁定,直到人工复位。

限位开关MR330-11Y-1366结构

限位开关，指为保护内置微动开关免受外力、水、油、气体和尘埃等的损害，而组装在外壳内的开关，尤其适用于对机械强度和环境适应性有特殊要求的地方。形状大致分为横向型、竖向型和复合型。

限位开关是一种常用的小电流主令电器。利用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，限位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。

在实际中，将限位开关安装在预先安排的位置，当装于机械运动部件上的模块撞击行程开关时，限位开关的触点动作，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。

限位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。
