Liftmaster LMWETXU Monitored Wireless Edge Transmitter NEMA 4X rated Bluetooth
The LiftMaster LMWETXU is the monitored wireless edge transmitter used with the LiftMaster LMWEKITU wireless edge receiver system. It connects to monitored resistive safety edges mounted on the moving gate and sends the edge status wirelessly to the receiver. This helps avoid running a hardwired edge cable across moving gate sections while still supporting monitored entrapment protection.
Each LMWETXU transmitter accepts up to two wired resistive edges and communicates using low-energy Bluetooth up to 130 ft under favorable conditions. It is NEMA 4X rated for outdoor gate installations and is commonly used when adding more monitored edge zones to an LMWEKITU system or replacing a damaged transmitter. It must be paired with the correct receiver and compatible monitored resistive edge sensors.

Technician Note
When adding a transmitter, label the edge zone and test open/close edge function after programming. The transmitter location and nearby metal can affect range.
Before Ordering
- Confirm an LMWEKITU receiver is already installed or being installed
- Confirm the edge sensor is a monitored resistive edge
- Confirm the operator supports monitored safety edge input
- Check transmitter range and mounting location
- Use the required AA lithium battery type listed for the system
Important Ordering Warnings
- This transmitter is not a standalone safety system without the receiver
- Do not use with contact-closure edges
- Do not bypass or ignore monitored safety faults
Professional Advisory
For any motor, harness, or monitored safety device replacement involving live voltage, unsafe gate movement, or uncertain wiring, use a qualified gate or garage door technician. Do not bypass safety devices to keep an operator in service.
Product Questions & Answers
Is LMWETXU a complete wireless edge kit?
No. LMWETXU is the transmitter. A compatible LMWEKITU receiver system is required.
How many edges can one LMWETXU transmitter accept?
One transmitter can accept up to two wired monitored resistive edges.
What edge types work with LMWETXU?
It is intended for compatible monitored resistive edges such as LiftMaster L50 and S50 edge systems when approved for the operator application.
What is the listed wireless range?
The listed range is up to 130 ft, but line of sight, metal obstructions, and site conditions can reduce actual range.
Can this be used to bypass a failed safety edge?
No. Safety devices should not be bypassed. Replace or repair failed monitored safety components and test the system before use.
