[Electrical] Test AW020145-PHOTOENTERRUPTOR.

[renato1301]

Good morning everyone, somebody knows of voltage and current of operation of AW020145-PHOTOENTERRUPTOR.
I want to test the disassembled part of the machine.

Re: Test AW020145-PHOTOENTERRUPTOR.

verify the connections with point to point but I am pretty sure almost all photointerruptors are 5V. Should be a 5V, a GND, and a signal that will also be 5V but change with status of blocked or not. Why not use the input check mode of the copier and check in the machine?

This sensor is around $2 (CAN). Why are you wasting your time wanting to test it? What is your actual problem that has you going down this "rabbit" hole?

Re: Test AW020145-PHOTOENTERRUPTOR.

I stand corrected. The sensor is $1.30 (CAN) on myricoh.

Dear Coptech, thanks for your answer, I checked the machine and did not get a response from the sensor, so I would like to test if it is just this sensor or have other problems.

Dear Gary Bowen, here in my country (Brazil) things are not so easy to find and only a sensor of this cost R$ 79.00 (BRL), it is very difficult to find.

Re: Test AW020145-PHOTOENTERRUPTOR.

$1.30 CAN is approx $2 US. How much is $79 BRL in US dollars? Again, what is your original error/ jam code? You are probably headed in the right direction - sensors do fail but the more info you provide, the better the Copytech brain trust can help you.

Re: Test AW020145-PHOTOENTERRUPTOR.

Look at the parts catalog to see where else in the machine the same sensor might be located. Swap the sensors to see if you fix your problem but create another one in the location where you borrowed the sensor. Quick and easy way to determine if it is indeed the sensor or not.

It gives approximately 20 $ American dollars, or else buy in Aliexpress 90 days of waiting to deliver. :-(

Ouch!

Re: Test AW020145-PHOTOENTERRUPTOR.

This works on every photointerrupter:

Leave it plugged into the copier and powered ON. Use you're meter on 5vdc range. Meter each pin to frame ground. There are (3) pins:

ground: 0.0vdc
supply voltage: 5.0vdc
output: 0.2 to 5.0vdc, depending if the sensor is blocked or unblocked

Simple! =^..^=

Be aware, a photo sensor may appear to function correctly in a static test, removed from machine, and still be defective. Many fail dynamically due to hysteresis caused by age. It only takes a couple of milliseconds delay to generate a jam detect.

Re: Test AW020145-PHOTOENTERRUPTOR.

I was able to test and the problem was even the sensor, I used a part of his idea and I got another sensor, but I mounted a small electrical scheme, to identify even when it is the infrared emitter that are burned, looking at the camera of the cell phone or when the problem is in the phototransistor, through a resistive divider that generates pulses when a barrier is present. Many thanks to all for the help.
