Help identifying a barrier sensor (or a suitable replacement)

[ogl]

Hello!

So I have a barrier sensor that I have extracted from a cycling trainer - particularly the Elite Direto - which I intend to use in a project. However, my Direto has two of these sensors and I need a couple more, so I would like to know where I can buy some more. The thing is, I have not been able to locate any reference number on the part in order to Google it, so I'd greatly appreciate any suggestions.

Before you tell me to just go buy any barrier sensor, I will say that I am interested in the barrier sensor from a cycling trainer because I am looking for a sensor capable of moving signals of up to 5-10 MHz, and I know that because of how this trainer measures power, it must have very accurate measurements by the barrier sensors (For the curious out there, if you want to see how it works, check this out: https://www.elite-it.com/en/innovations/optical-torque-sensor-power-meter-integrated. Pretty cool!!)

Attached to the post are three pictures of said sensor, two of the upper side and one of the lower side, in which you can see some numbers but they seem to be for internal reference within Elite, as googling them does not give any useful information.

I could also do with the product name/reference of a barrier sensor that moves signals of 5-10 MHz, it doesn't necessarily have to be this one.

Thank you all for your help!!

This so-called "Barrier Sensor" looks just like an ordinary infrared diode --infrared transistor detector.  It easily detects any type of infrared opaque material(i.e. a piece of metal,  paper, plastic, etc.) that is placed in the slot between the IR transmitter and detector square modules.

You can salvage them for free from any old PC printer or buy them for a few cents on ebay.

That link didn't work.
However, the photosensor in an "optical interrupter" (aka photo interrupter) is not usually rated for 5 MHz operation.
This Omron part  https://www.mouser.com/datasheet/2/307/Omron_EE_SX1330_2_Datasheet_English-3315007.pdf  is considered to be "high speed", but the rise and fall times of the electrical output are roughly 10 us each at 100 ohms load, increasing with higher load resistance.
Also note the datasheet graph for the (slow speed) output as a function of blocker position (figs. 8 and 9).
