欧姆龙omron  HL-5030接近开关 限位开关 行程开关 微动开关防水防油

接近开关是一种无需与运动部件进行机械直接接触而可以操作的位置开关，当物体接近开关的感应面到动作距离时，不需要机械接触及施加任何压力即可使开关动作，从而驱动直流电器或给计算机（plc)装置提供控制指令。接近开关是种开关型传感器（即无触点开关），它既有行程开关、微动开关的特性，同时具有传感性能，且动作可靠，性能稳定，频率响应快，应用寿命长，抗干扰能力强等、并具有防水、防震、耐腐蚀等特点。产品有电感式、电容式、霍尔式、交、直流型。

Omron HL-5030 proximity switch limit switch travel switch microswitch waterproof and oil proof

A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the operating distance, it can be actuated without mechanical contact and applying any pressure, thereby driving DC appliances or providing control commands to computer (PLC) devices. The proximity switch is a switch type sensor (i.e., a contactless switch) that combines the characteristics of a travel switch and a microswitch with sensing performance, reliable action, stable performance, fast frequency response, long application life, strong anti-interference ability, and features water resistance, shock resistance, and corrosion resistance. Products include inductive, capacitive, Hall, AC, and DC types.
