德國(guó)*SCHMERSAL光電式接近開(kāi)關(guān)利用光電效應(yīng)做成的開(kāi)關(guān)叫光電開(kāi)關(guān)。將發(fā)光器件與光電器件按一定方向裝在同一個(gè)檢測(cè)頭內(nèi)。當(dāng)有反光面(被檢測(cè)物體)接近時(shí),光電器件接收到反射光后便在信號(hào)輸出,由此便可“感知”有物體接近。 在SCHMERSAL接近開(kāi)關(guān)內(nèi)設(shè)有振蕩器諧振電路,它是利用一個(gè)開(kāi)放式的線(xiàn)圈產(chǎn)生定向高頻電磁( RF )場(chǎng),穿透?jìng)鞲衅鞴ぷ鞫嗣鎮(zhèn)鞒鰜?lái)。如果一個(gè)金屬目標(biāo)進(jìn)入這一區(qū)域,開(kāi)關(guān)感應(yīng)產(chǎn)生的渦電流因此降低。感應(yīng)渦電流從 LC電路中吸收能量(L:線(xiàn)圈 C :電容器) 。振蕩電路中的負(fù)載在振幅上產(chǎn)生一個(gè)衰減值,振蕩減弱。 上海維特銳直接從德國(guó)SCHMERSAL原廠(chǎng)家拿貨,直接供應(yīng)各種SCHMERSAL感應(yīng)傳感器,施邁賽磁性開(kāi)關(guān),施邁賽安全開(kāi)關(guān) IFL 10-180L-11P IFL 10-180L-11STP IFL 10-200-01 IFL 10-200-10 IFL 10-200L-11P IFL 10-200L-11STP IFL 10-30-01T IFL 10-30-01T-1310 IFL 10-30-10/01 IFL 10-30-10T IFL 10-30-10T-1310 IFL 10-30L-10/01N IFL 10-30L-10/01P IFL 10-30L-10TN IFL 10-30L-10TP IFL 10-30L-11STP-1766 IFL 10-30L-11TN IFL 10-30L-11TP IFL 10-30L-11TP-1766 IFL 10-30M-10N IFL 10-30M-10P IFL 10-30M-10ST1P IFL 15-30-01T IFL 15-30-01T-1310 IFL 15-30-10/01 IFL 15-30-10T IFL 15-30-10T-1310 IFL 15-300-01T IFL 15-300-10/01 IFL 15-300-10/01D IFL 15-300-10T IFL 15-300L-01TP IFL 15-300L-10/01N IFL 15-300L-10/01P IFL 15-300L-01TN IFL 15-300L-01TP IFL 15-300L-11TN IFL 15-300L-11TP IFL 15-300M-10N IFL 15-300M-10P IFL 15-30L-10/01N IFL 15-30L-10/01P IFL 15-30L-10TN IFL 15-30L-10TP IFL 15-30L-10TP-2130 IFL 15-30L-11STP-1766 IFL 15-30L-11TN IFL 15-30L-10TP IFL 15-30L-10TP-1766 IFL 15-30M-10P IFL 15-30M-10ST1P IFL 15-333-10/01 IFL 15-333-10/01A IFL 15-333-11YNG IFL 15-333-11YPG IFL 15-333E-01 IFL 15-333E-10 IFL 15-333E-11N IFL 15-333E-11ZPG IFL 2-12-01 IFL 2-12-01N IFL 2-12-01P IFL 2-12-01STN IFL 2-12-01ST IFL 2-12-01T IFL 2-12-10 IFL 2-12-10N IFL 2-12-10P IFL 2-12-10STN IFL 2-12-10STP IFL 2-12-10STP-2033 IFL 2-12L-01N IFL 2-12L-01P IFL 2-12L-01STN IFL 2-12L-01STP IFL 2-12L-10N IFL 2-12L-10P IFL 2-12L-10STN IFL 2-12L-10STP IFL 2-12M-01N IFL 2-12M-01P IFL 2-12M-01STN IFL 2-12M-01STP IFL 2-12M-10N IFL 2-12M-10P IFL 2-12M-10STN IFL 2-12M-10STP IFL 2-250-01 IFL 2-250-10 IFL 2-250-10N IFL 2-250-10N-1716 IFL 2-250-10P
