INTERAPP ES2.PFF31接近開關(guān)是一種無需與運(yùn)動(dòng)部件進(jìn)行機(jī)械直接接觸而可以操作的位置開關(guān)，當(dāng)物體接近開關(guān)的感應(yīng)面到動(dòng)作距離時(shí)，不需要機(jī)械接觸及施加任何壓力即可使開關(guān)動(dòng)作，從而驅(qū)動(dòng)直流電器或給計(jì)算機(jī)（plc)裝置提供控制指令。接近開關(guān)是種開關(guān)型傳感器（即無觸點(diǎn)開關(guān)），它既有行程開關(guān)、微動(dòng)開關(guān)的特性，同時(shí)具有傳感性能，且動(dòng)作可靠，性能穩(wěn)定，頻率響應(yīng)快，應(yīng)用壽命長(zhǎng)，抗干擾能力強(qiáng)等、并具有防水、防震、耐腐蝕等特點(diǎn)。

INTERAPP The ES2.PFF31 proximity switch is a position switch that can be operated without direct mechanical contact with the moving parts. When the object is close to the sensing surface of the switch to the operating distance, no mechanical contact is required and any pressure is applied So that the switch action, which drive the DC electrical appliances or to the computer (plc) device to provide control instructions. The proximity switch is a kind of switch type sensor (that is, no contact switch), it has both trip switch, micro switch characteristics, but also has sensor performance, and reliable, stable performance, fast frequency response, long life, anti-interference Strong ability, and has a waterproof, shock, corrosion and other characteristics.
