*德國SICK施克傳感器光幕發射器安全光幕也就是光電安全保護裝置（也稱安全保護器、沖床保護器、紅外線安全保護裝置等）. 在現代化工廠里，人與機器協同工作，在一些具有潛在危險的機械設備上，如沖壓機械、剪切設備、金屬切削設備、自動化裝配線、自動化焊接線、機械傳送搬運設備、危險區域（有毒、高壓、高溫等），容易造成作業人員的人身傷害。安全光幕由投光器和受光器兩部分組成。投光器發射出調制的紅外光，由受光器接收，形成了一個保護網，當是有物體進入保護網，當從中有光線被物體擋住，通過內部控制線路，受光器電路馬上作出反應，即在輸出部分輸出一個信號用于機床如沖床，壓力機等緊急剎車。光幕有著非常廣泛的應用，比如在需要不斷送取料的沖壓設備上，如果安裝接觸式安全防護門，則需要操作人員頻繁地開關防護門，這樣不但增加了操作人員的工作量，而且降低了生產效率。在這種情況下，采用光柵和光幕就是*的選擇。

傳感器的特點包括：微型化、數字化、智能化、多功能化、系統化、網絡化，它不僅促進了傳統產業的改造和更新換代，而且還可能建立新型工業，從而成為21世紀新的經濟增長點。微型化是建立在微電子機械系統（MEMS）技術基礎上的，目前已成功應用在硅器件上做成硅壓力傳感器。
