二、工作原理
本產(chǎn)品基于電磁感應(yīng)原理工作，當(dāng)金屬目標(biāo)物進(jìn)入預(yù)設(shè)感應(yīng)范圍時，內(nèi)部振蕩電路會產(chǎn)生磁場變化，通過信號處理單元轉(zhuǎn)換為開關(guān)量輸出。設(shè)備內(nèi)置過載保護(hù)模塊，可有效抑制電壓波動和電磁干擾，確保在-25℃至+70℃環(huán)境溫度下保持穩(wěn)定檢測精度。
三、應(yīng)用領(lǐng)域
適用于機床設(shè)備、包裝機械、輸送系統(tǒng)等工業(yè)場景的位置檢測，可實現(xiàn)對氣缸活塞定位、傳送帶物料檢測、設(shè)備安全防護(hù)等功能。典型應(yīng)用包括：自動化生產(chǎn)線工件到位檢測、電梯平層控制、立體倉儲設(shè)備定位等需要非接觸式檢測的場合。
四、技術(shù)參數(shù)
檢測距離：10mm±10%（鐵質(zhì)材料）
工作電壓：DC 10-30V
輸出類型：NPN常開型
響應(yīng)頻率：100Hz
防護(hù)等級：IP67
導(dǎo)線長度：標(biāo)準(zhǔn)2米（可定制）
五、產(chǎn)品特點
- 三線制接線設(shè)計，支持電源極性反接保護(hù)
- LED狀態(tài)指示燈便于現(xiàn)場調(diào)試
- 全封閉結(jié)構(gòu)防塵防油污
- 抗焊接火花干擾設(shè)計
