發(fā)射型光電開(kāi)關(guān),GKF-2
產(chǎn)品概述
發(fā)射型光電開(kāi)關(guān)GKF-2是一種高性能的非接觸式檢測(cè)設(shè)備,廣泛應(yīng)用于工業(yè)自動(dòng)化控制領(lǐng)域。它通過(guò)發(fā)射紅外光或可見(jiàn)光束,利用物體對(duì)光束的遮擋或反射來(lái)檢測(cè)目標(biāo)物體的有無(wú)或位置變化。該產(chǎn)品采用集成電路技術(shù)和表面安裝工藝,具備穩(wěn)定性高、響應(yīng)速度快、抗干擾能力強(qiáng)等特點(diǎn),可適配多種復(fù)雜環(huán)境下的檢測(cè)需求。所有能反射光線的物體(包括金屬和非金屬)均可被檢測(cè),適用于生產(chǎn)線計(jì)數(shù)、安全防護(hù)、液位控制等場(chǎng)景。115
產(chǎn)品特點(diǎn)
GKF-2設(shè)計(jì)緊湊,功能多樣,支持漫反射式、反射板式和對(duì)射式三種檢測(cè)模式。其智能化的延時(shí)、展寬和外同步功能可有效避免誤操作,同時(shí)自診斷系統(tǒng)能實(shí)時(shí)監(jiān)控工作狀態(tài)。產(chǎn)品采用電隔離設(shè)計(jì),輸入與輸出回路完全絕緣,確保使用安全。此外,它的檢測(cè)距離靈活可調(diào),能適應(yīng)不同尺寸物體的識(shí)別需求,例如在自動(dòng)門控制或包裝機(jī)械中實(shí)現(xiàn)精準(zhǔn)定位。冷光源技術(shù)(如紅外光、紅色光)的運(yùn)用使其對(duì)檢測(cè)物無(wú)損傷,且壽命顯著優(yōu)于傳統(tǒng)機(jī)械開(kāi)關(guān)。121
技術(shù)原理
GKF-2的核心原理是通過(guò)發(fā)射器將輸入電流轉(zhuǎn)換為光信號(hào),接收器根據(jù)光線強(qiáng)弱變化觸發(fā)開(kāi)關(guān)動(dòng)作。當(dāng)被測(cè)物體進(jìn)入檢測(cè)區(qū)域時(shí),光束被阻斷或反射,接收器同步輸出電信號(hào)至控制系統(tǒng)。產(chǎn)品內(nèi)置光學(xué)元件(如透鏡和光圈)以優(yōu)化光路聚焦,并采用脈沖調(diào)制技術(shù)降低環(huán)境光干擾。其回差特性可避免因物體微小晃動(dòng)導(dǎo)致的信號(hào)抖動(dòng),確保輸出穩(wěn)定。典型應(yīng)用包括沖床安全防護(hù)、流水線產(chǎn)品分揀及倉(cāng)儲(chǔ)物流的物料識(shí)別等。11521
應(yīng)用場(chǎng)景
GKF-2的泛用性使其在多個(gè)行業(yè)表現(xiàn)卓越。在制造業(yè)中,它用于機(jī)械臂運(yùn)動(dòng)計(jì)數(shù)或傳送帶物料檢測(cè);在安防領(lǐng)域,可作為煙霧報(bào)警器的觸發(fā)元件;在輕工業(yè)中,則用于透明瓶體灌裝液位的監(jiān)控。其非接觸式特性特別適合高速運(yùn)動(dòng)物體或易損材料的檢測(cè),例如紙張、薄膜或玻璃制品。產(chǎn)品還可集成于自動(dòng)門系統(tǒng),通過(guò)人體感應(yīng)實(shí)現(xiàn)無(wú)接觸通行。1615
英文介紹 (Introduction)
The GKF-2 emission-type photoelectric switch is a versatile sensing device designed for non-contact object detection in industrial automation. It emits modulated infrared or visible light beams to identify targets by analyzing interruptions or reflections, suitable for diverse materials including metals, plastics, and liquids. With compact structure and SMT technology, it offers features like high-speed response (millisecond-level), adjustable detection range, and anti-interference capabilities. The built-in self-diagnosis function enhances operational reliability.
Key advantages include three operating modes (diffuse-reflective, retro-reflective, and thru-beam), enabling flexible integration into production lines for tasks such as positioning, sorting, or safety guarding. The electrical isolation between input/output circuits ensures compatibility with complex control systems. Typical applications span packaging machinery, automated doors, and conveyor belt monitoring, where its maintenance-free design and long service life significantly reduce downtime.
The product’s optoelectronic system converts light intensity variations into stable switching signals via synchronized circuitry. Advanced pulse modulation minimizes ambient light effects, while the hysteresis function prevents false triggering. Ideal for harsh environments, it supports applications from precision assembly to bulk material handling, demonstrating consistent performance across temperature fluctuations and dust-prone areas. 12125
