- PCB dimensions – Transmitter : 43 mm x 56 mm & Receiver : 80 mm x 73 mm
Where do you get these circuit boards that are 4 Channel Infra Remote Controller Using 4 Relay, HT12A HT12D
Hi,
MOQ for these board is 25.
WHere can i get this pcb printed ?
Hi,
R from india?
Thanks,

I came across this 4 Channel Infra Remote Controller Using 4 Relay, HT12A HT12D while searching. I have the following questions.
Could the little push buttons on the transmitter be substituted and activated with micro switches (limit switches) that would be positioned remote of the unit?
What is the transmission distance?
Could two of these systems be utilized for use on the one machine. That is 8 remote switches activating 8No 10mm solenoids?
My system is powered by 12volt battery.
Hi,
The remote works with the distance of 10-15 feet, the tactile switch can be replaced with microswitch.
HT12A and HR12D ICs not recommended for a new design, it would be good if you can use Arduino based remote link is bellow,

Hi! I like ur design. I have proximity sensor w/c is working from 10-30vdc what i need is 6 prox. Sensors inputs with 100m distance and with 2 sets of trans/receiver. Do the design capable of?
Hi this is possible, can you share more details about sensor you are using?
