Are the 2 items , 1 receiver and 1 sender?
I need to replace two garage door sensors. Is this the sending or receiving sensor? Is this one pair of both receiving and sending sensor? Thanks.
How do you differentiate between the sending unit and the receiving unit?
Will these work with a Liftmaster 1046 that came with no sensors? I saw indication the "Model 70" sensor might work.

Excellent Seller and Product

The hurricanes took out our garage door sensors and even if we could have gotten on the garage door installers calendar, they wanted $300.00 to replace the sensors that had gotten wet in the flood. We easily replaced the damaged ones for less than a hundred dollars and they work great. So appreciative the seller made sure we got this order even when mail was a mess.

Great product

This is a repeat purchase because I have 2 doors. OEM quality replacement and an easy install.

Safety Sensors Work As Advertised.

Perfect replacement for my 27 year old originals. If available, would have replaced the rusty old mounting hardware as well.

Works as Expected

Fortunately, I was able to locate this replacement part on the seller`s site. Our +17 year old sensor stopped working as soon as the temperature dropped below 0 Celsius (32 Fahrenheit). The receiving eye`s green LED would go blank and attempts to close the garage door would cause it to pop open. As an interim solution we had to open the door, drive out, and then run back into the garage to close the garage door by pressing and holding down the main door button.Recommended extra tools:Small wire cutter/stripperPliersInstructions were relatively simple, but you need to remember BOTH sensors must be replaced otherwise the system will not work. Look on the tail end of the sensors to see the identifying label.Below is what I encountered:I am not sure why Chamberlain/Liftmaster changed the product, but the original sensors used easily detachable plugs where the sensors had the receiving female end and the wall wire had the male plug. These newer replacement sensors only use wires. The wires coming from the wall have plugs that must be cut off and then spliced onto the new sensors' wire (Note: Follow the package's instructions and unplug the garage motor first). You don't want to strip down the wires too deeply in order to avoid having exposed copper wire remaining outside of the connector. When you put the wire into the connector take a look at the top of the connector to see how deep the copper wiring has gone.Troubleshooting experiences:I changed the Receiving Eye sensor only, but the system still did not work. This is when I discovered that you need to change both the Sending and Receiving sensor.My clumsiness or numbness from the cold may have cut too deeply into the copper wiring. After successfully installing and testing the garage door I tried to tape down the wiring. This caused the LED lights to lose connection, but after fiddling with the wires I realized that my I may have cut too deeply into the wires. I did a temporary fix by jiggling the wires until it worked again, then used electrical tape to keep squeezing the wires together in that position.Maybe when the weather warms up (or if my wires loosen again) I will re-do the wiring, but I ran out of those Wire connectors.Otherwise - this replacement part works as expected.Thanks

Works great!

My Chamberlain garage door opener is over 25 years old and when my original sensor lights just wouldn't work I thought I was going to have to buy a completely new garage door opener. No need to do that since these replacement sensors worked great and were compatible with my 25+ year old Chamberlain garage door opener.
