Hi I have read that in nuclear industries, optical isolators should be used for acheiving independence i. This little component has 6 legs each of them having a different usage.

Originally submitted by fabio on This is the circuit: We then have leg 4, datasheey, 6 respecly emitter, collector and base. It can be easealy understood while looking at the following picture from the 4N35 datasheet which shows us the inside schematics of the 4N So, it basically do the same of the transistor example above but this time we are using an optocoupler.

For example one circuit could be the one powered by Arduino: Blondel not verified on Mon, So, we have leg 1 and 2 near the printed dot on the chip that’s visible on it if we look carefully that acts respectly as anode and cathode.

Vishay – 4N35, 4N36, 4N37 – Optocoupler, Phototransistor Output, with Base Connection

To get the code refer to the Hello World blog post. The transitor base will be datasneet to an Arduino output pin. We already know these terms from the transistor introduction above. This is good when you don’t want a component further along in the system to affect previous components.

A diode is a two terminals electronic component that conducts electric current only in one direction. They are two indipendent circuit.

IC 4N35 Optocoupler

Submitted by Pierre-Alain Dorange not verified on Tue, Optocouplers An optocoupleralso called opto-isolatoroptical isolatoroptical coupling devicephotocoupleror photoMOSis an electronic device that usually contains both an infrared light-emitting diode LED and a photodetector and opgocoupler them to transfer an electronic signal between element of circuits maintaining them electrically isolated. I studied electronics before going to IT embedded systems and I wanted to get back to electronic as a hobby.

Search Search this datawheet I’ll briefly describe them and we’ll see some simple examples of circuits built upon an Arduino Duemilanove board which make use of them.

When a voltage is applied to the LED, the LED lights and illuminate the photodetector which produces an output current on the photodetector: The fixed circuit in this section, by using a pull-down resistor doesn’t show this effect and works reliably.

This is the result: The simple circuits I built will be used as base for more complex stuff. A similar result could optoocoupler been achieved using the MOS Irf transistor. Thanks for Submitted by fabio on Sun, This behaviour make the transistor the perfect component for interface two different circuits operating at different voltages.

Good article Submitted by AN not verified on Sun, The section about the 4n35 says: Transistors A transistor is a semiconductor device which can be used to amplify or switch electronic signals.

Thanks for noticing and posting a comment.

Could you please explain to me why? I have fixed the image and also added an improved circuit which should be better. You can see a demo in the video below. As you can see each time the output on pin 2 is HIGH our transistor will get a voltage on its base connector resulting in the collector and the emittor getting connected. Hi I have read that in 3 years 29 weeks ago wonderful! An optical isolator on the other hand datasneet similar datwsheet a diode in that it only lets unidirectional transmission.
