Infared transceiver: HS21A011 IR transceiver

[RepairingDave]

This is more curiosity than anything.
I have brought a job lot which included 2 packs of 'HS21A011 IR transceivers'.

I can't find anything online about them, so was wondering if anyone knew what they would be used for and if they have any use/value.

The only thing is says on both is 'OMRON'.

Photos below (hopefully).

Ignoring the part number, they appear to be a standard IR LED emitter/receiver pair.
There are plenty available (along with application notes and datasheets), from the hobby suppliers, i.e.

IR Break Beam Sensor with Premium Wire Header Ends - 5mm LEDs

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way ...

I presume it is similar to these devices in the following links.

Used for one way communication, eg remote controls. Or as a break beam detector sensor for garage door.
The two wire device being the transmitter and the other three wire being the receiver.

Thanks for the information RandomGrinch and SFK.

I assume the ones I have are a simple on-off switch and not capable of transmitting or receiving any data.

Looking at it again, I think Random was correct in that it is a simple break beam sensor. And not my suggestion of remote control.
It could be used for data, but one way and slow data.
