In automation, detecting part presence is pretty important, and this is most commonly done with proximity sensors.

Even within this part category, there are some important distinctions you should know about.

Firstly, because they use invisible light beams and they're sweet, let's talk about infrared sensors.

I've got two different types here.

This all-in-one style is a diffuse-style sensor, which emits the infrared light and looks for it bouncing back all in the same little tube.

Super easy to use and mount.

Downside is it can be less accurate in outdoor environments or with shiny and dark parts.

The other form of infrared sensor is a through beam sensor, and these are usually two pieces, with the emitter on one side of your conveyor or detection zone, and a receiver on the other.

They're a little more complicated to set up than the single unit, but much more reliable too.

These little fellas are inductive sensors, meaning they can only see metal or things that have inductive current.

You can run cardboard or plastic by these without detecting anything, because they're only useful for detecting metal.

Lastly, the capacitive style sensors can see a lot more and even be used to detect powders or liquids, with the trade-off being they can actually be too sensitive

and often need their sensitivity dialed back down a bit with a potentiometer to reduce noise.

One more pro gamer tip, pretty much all of these sensors can be found in PNP or NPN arrangement.

You can either source 24 volts to your PLC with a PNP sensor

or sync back to 0 volts with an NPN sensor.

Most digital input cards on a PLC can only handle one or the other.

Make sure you buy a sensor to match your card.

So which one of these sensors do you think is the right call for detecting components on our conveyor system?

需要注意的發音

說話人用了 4 次縮略和弱讀形式，例如 they're, I've。請按聽到的簡短形式來說。

“sh” 和 “zh” 音: distinction /dɪˈstɪŋkʃən/, detection /dɪˈtɛk.ʃən/, automation /ˌɔ.təˈmeɪ.ʃən/, potentiometer /pəˌtɛn(t)ʃiˈɑmɪtəɹ/
長單詞——注意重音位置: complicated /ˈkɑm.plɪˌkeɪ.tɪd/, invisible /ɪnˈvɪzəb(ə)l/, sensitivity /ˌsɛn.səˈtɪv.ə.ti/, proximity /pɹɒkˈsɪm.ɪ.ti/, automation /ˌɔ.təˈmeɪ.ʃən/

如何用這段影片練習

先完整聽一遍影片，不要開口，記下不認識的單詞。
先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
錄下自己的聲音並與原聲對比，特別注意 sensor, detect, infrared 這類單詞。

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
