详细介绍

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，频率响应快，应用寿命长，抗干扰能力强等、并具有防水、防震 等特点。产品有电感式、电容式、霍尔式、交、直流型。

接近开关又称无触点接近开关，是理想的电子开关量传感器。当金属检测体接近开关的感应区域，开关就能无接触，无压力、无火花、迅速发出电气指令，准确反应出运动机构的位置和行程，即使用于一般的行程控制，其定位精度、操作频率、使用寿命、安装调整的方便性和对恶劣环境的适用能力，是一般机械式行程开关所不能相比的。它 地应用于机床、冶金、化工、轻纺和印刷等行业。在自动控制系统中可作为限位、计数、定位控制和自动保护环节等。

Detailed introduction

Proximity switch is a position switch that can be operated without mechanical direct contact with moving parts. When the object is close to the sensing surface of the switch to the operating distance, no mechanical contact and pressure can be applied to make the switch operate, thereby driving the DC electrical appliance or providing control instructions to the computer (plc) device.

Proximity switch is a switch type sensor (that is, contactless switch), which has the characteristics of stroke switch and micro-switch, and has sensing performance, and reliable action, fast frequency response, long application life, strong anti-interference ability, and waterproof, shockproof and other characteristics. Products are inductive, capacitive, Hall, AC, DC type.

Proximity switch, also known as contactless proximity switch, is an ideal electronic switching sensor. When the metal detector is close to the sensing area of the switch, the switch can be non-contact, no pressure, no spark, quickly issue electrical instructions, accurately reflect the position and stroke of the moving mechanism, even for general stroke control, its positioning accuracy, operating frequency, service life, convenience of installation and adjustment and the ability to apply to harsh environments. Is the general mechanical travel switch can not be compared. It is used in machine tools, metallurgy, chemical industry, textile and printing industries. In the automatic control system can be used as limit, counting, positioning control and automatic protection link.
