Need a Transmitter-Receiver circuit
(OP)
I need to transmit a 500 hz square wave without interference upto a distance of 50~60 meters that has to be picked up by the receiver at the other end. For this I need to have a transmitter-receiver circuit. Could someone plz help with a schematic! Thanks in advance!

Or is 500Hz the resultant signal you want at the receiver?
What do you mean by "without interference"?
Is this inside a building or out in space?

This approach gives you some immunity from interferring signals.
You might want to try a 9MHz carrier that is shifted to 10.7MHz during pulse detection. 10.7MHz filters are easy to find.
Just one possible solution.

has a 40Khz modulated IR receiver which is able to
work for that distance even without additional optics.
