Is it possible to splice this garage door safety sensor wire with some other wire

garage-door-openerwire

I currently have these sensors:

An accident occurred a few days ago and the cable to the receiver was snapped apart. I am going to replace the opener in a few years anyway and don't feel like buying and installing two new sensors (would have to run the wires, align the sensors, bleh).

If I could buy some wire and splice it to this one then that would be awesome. However, I don't know what kind of wire to buy. Someone please let me know if I can do this.

Garage door sensors and buttons are low voltage (usually 24vdc), and low enough current that for the short runs typical in a garage you don't need very large cables.

18awg "thermostat wire" will work, but you can go even cheaper with 22awg wire, usually sold as "security system" or "central vac" wiring (2 conductor), or telephone station wire (4 conductor - though you only hook up two).

Also, a little bit of heat shrink tubing goes a long way to making a neat and professional looking splice.
